Russell Maze: Tennessee: Robert Roberson: Texas: Shaken Baby Syndrome: Medical examiner Dr. Bruce Levy backtracks on the shaken baby autopsy that sent Russell Maze to prison for life - and now says he made a mistake, NBC News (Reporters Dan Slepian and Erik Ortiz) report, noting that Dr. Levy's finding that Alex Maze died of shaken baby syndrome was critical in the murder conviction of his father, Russell Maze - and that decades later, Levy says he believes Maze is innocent."…"Levy remains hopeful the legal system can find a way to free Maze. He winced as he thought of his role in the case, how a couple has been separated through decades and how he believes an innocent man remains in prison. “I would like Russell to come home,” Levy said. “I think he has paid a horrible price for mistakes that I and others have made.”


QUOTE OF THE DAY: "This month, in his first public comments on the case, Levy told NBC News that after having received information he never knew about Alex’s medical history, he came to a startling conclusion: He was wrong about Alex’s being abused, and he believes Maze is innocent. “I have to remember that I’m not perfect and I can make mistakes,” Levy said. “And the best that I can do, is when I come to realize that, is to admit that I have made a mistake and try to do what I can to rectify that.”

——————————————

SECOND QUOTE OF THE DAY: "Kaye, 62, said that while she fights for her husband’s freedom, her anger also gives way to gentler moments, loving memories of Maze sweetly rocking Alex to sleep when the world revolved around her family of three. “The bad thing is we are in our 60s now,” Kaye said. “We were in our 30s when this happened. So now we are closer to the end of our road. How much time we have left together, nobody knows.”

——————————————

PASSAGE OF THE DAY: "Thousands of caregivers have been arrested based on the long-held medical belief that three symptoms — brain swelling, bleeding in the brain and bleeding behind the eyes — indicate that a young child was deliberately shaken. But in the decades since Maze was convicted, there has been a growing acknowledgment among experts that the symptoms once believed to be proof of shaken baby syndrome, also known as abusive head trauma, can appear in children for other reasons, like complex medical conditions. And with that shift in understanding, a movement has been growing to re-examine — and potentially reverse — some shaken baby convictions, particularly when the evidence of abuse now appears questionable."

———————————————————

PASSAGE TWO OF THE DAY: "In October, NBC News’ “The Last Appeal” podcast investigated the high-profile case of Robert Roberson, a condemned man on Texas’ death row who was convicted of fatally shaking and abusing his 2-year-old daughter, Nikki, in 2002. On Oct. 9, Texas’ highest criminal court halted the latest attempt to execute Roberson, sending his case back to a lower court for another review. “We are confident that an objective review of the science and medical evidence will show there was no crime,” Gretchen Sween, Roberson’s attorney, said at the time. Maze is still waiting for a similar breakthrough."

———————————————--

PASSAGE THREE OF THE DAY: "Brian Holmgren, the prosecutor who took Maze to trial, was previously on the advisory board of the National Center on Shaken Baby Syndrome, an organization dedicated to educating people about the diagnosis. He says that he and the jury got it right and that Maze should remain in prison. Anyone who disagrees “clearly did not understand what the heck they were talking about,” he told NBC News. But in 2023, nearly two decades after Maze’s conviction, Sunny Eaton decided that his case deserved a second look. Eaton, a former public defender, leads the conviction review unit in the Nashville district attorney’s office, reopening cases in which people were found guilty but may actually be innocent. The “shaken baby” diagnosis gave her pause. “I am a firm believer that whenever you have scientific testimony that has put someone in prison, we have to evaluate that scientific evidence and make sure that it still stands today,” she told NBC News. “The scientific evidence in this case was 25 years old.”

STORY: "Medical examiner backtracks on shaken baby autopsy that sent Russell Maze to prison for life," by Reporters Dan Slepian and Erik  Ortiz, published by NBC News, on December 16, 2025.  (Dan Slepian is an award-winning investigative producer and a veteran of "Dateline: NBC." Erik Ortiz is a senior reporter for NBC News Digital focusing on racial injustice and social inequality.)

SUB-HEADING: "A medical examiner's testimony put a father behind bars for life. Now he says he 'made a mistake.'"

SUB-HEADING: Dr. Bruce Levy's finding that Alex Maze died of shaken baby syndrome was critical in the murder conviction of his father, Russell Maze. Decades later, Levy says he believes Maze is innocent."



GIST:" In the summer of 2024, Dr. Bruce Levy, the former chief medical examiner of Tennessee, got a call asking whether he remembered the death of a baby boy, Alex Maze.

The name, from nearly 25 years earlier, faintly stirred Levy’s memory. Levy had conducted an autopsy on the 19-month-old boy, and he had concluded that Alex’s death was a homicide, the result of being violently shaken.

Levy’s testimony was critical in helping Nashville prosecutors secure a murder conviction against Alex’s father, Russell Maze, who was sentenced to life in prison.


For decades, Maze has denied abusing his son. He had been home alone with Alex in May 1999 when the baby suddenly stopped breathing. At the hospital, a pediatrician who specialized in identifying child abuse found what she said were clear signs that Alex was the victim of shaken baby syndrome. Levy later agreed.

Now, decades later, Levy was being asked to re-examine Alex’s death amid an initiative in Nashville investigating potential wrongful convictions. Intrigued, Levy said yes.

This month, in his first public comments on the case, Levy told NBC News that after having received information he never knew about Alex’s medical history, he came to a startling conclusion: He was wrong about Alex’s being abused, and he believes Maze is innocent.

“I have to remember that I’m not perfect and I can make mistakes,” Levy said. “And the best that I can do, is when I come to realize that, is to admit that I have made a mistake and try to do what I can to rectify that.”

Thousands of caregivers have been arrested based on the long-held medical belief that three symptoms — brain swelling, bleeding in the brain and bleeding behind the eyes — indicate that a young child was deliberately shaken.

But in the decades since Maze was convicted, there has been a growing acknowledgment among experts that the symptoms once believed to be proof of shaken baby syndrome, also known as abusive head trauma, can appear in children for other reasons, like complex medical conditions. And with that shift in understanding, a movement has been growing to re-examine — and potentially reverse — some shaken baby convictions, particularly when the evidence of abuse now appears questionable.

In October, NBC News’ “The Last Appeal” podcast investigated the high-profile case of Robert Roberson, a condemned man on Texas’ death row who was convicted of fatally shaking and abusing his 2-year-old daughter, Nikki, in 2002. On Oct. 9, Texas’ highest criminal court halted the latest attempt to execute Roberson, sending his case back to a lower court for another review. “We are confident that an objective review of the science and medical evidence will show there was no crime,” Gretchen Sween, Roberson’s attorney, said at the time.

Maze is still waiting for a similar breakthrough.

After he reviewed Maze’s case, Levy wrote an affidavit in September 2024 recanting his homicide finding and determining that Alex had succumbed to a “natural” death. He joined an ongoing effort by the Nashville district attorney’s office, which has been working to free Maze.

Levy reclassified Alex's cause of death as "undetermined" and manner of death as "natural" in 2024. Alex's legal name was Bryan.


Yet despite supporters in law enforcement and forensics fighting for his release, Maze remains behind bars. Since last year, both the trial court and the Tennessee Court of Criminal Appeals have declined to vacate his conviction. Maze’s struggle is emblematic of the uphill climb parents face when they try to combat charges of shaking their babies.

The latest decisions were yet another disappointment for Maze’s wife, Kaye, who has never wavered in her belief in her husband’s innocence. She was not home when Alex stopped breathing in 1999, but like her husband, she was also charged. She accepted what is called an Alford plea, allowing her to maintain her innocence and stay out of prison while pleading to reckless aggravated assault. She remains a convicted felon.

Her home in East Tennessee, where she moved to be closer to her husband’s prison, is filled with framed pictures of Russell and Alex, their buoyant expressions frozen in time.

“We had a whole life planned out,” Kaye told NBC News in her first interview about the ordeal. “You know, you have a baby with so much hope, so much promise. And to have it all just ripped away from you is just — it’s sorrow and anger. And anger is pretty high up there.”

The Tennessee Department of Correction declined to make Russell Maze available to comment in person or by phone.

The Mazes’ experience as parents was fraught from the very beginning.

Alex was born prematurely in March 1999, weighing just 3 pounds, 12 ounces. He spent his first days in a neonatal intensive care unit for ailments including jaundice, anemia and a racing heart rate.

The Mazes, in their 30s, were vigilant first-time parents. Russell worked for a trucking company, and Kaye picked up a couple shifts as a vendor at a music festival. Alex was sent home from the hospital wearing a heart monitor. The Mazes took him to doctors seven times over the next three weeks, Kaye said.

In May 1999, when Alex was 5 weeks old, Kaye stepped out to buy formula. She returned home less than 30 minutes later and saw an ambulance. Russell said he had dialed 911 after Alex, who had been fussy and vomiting, stopped breathing. He said he attempted CPR until the paramedics arrived and resuscitated the baby.


At Nashville’s Children’s Hospital at Vanderbilt, one of the first doctors to see Alex mistakenly described him as a “full term baby” with “no significant past medical history.” They examined his tiny body and noted head and abdominal bruising, bleeding in the eyes, a fractured clavicle and irreparable brain damage, court records show. Dr. Suzanne Starling, then the director of Vanderbilt’s child abuse and neglect program, wrote that “this constellation of injuries is seen in abusive head trauma.”

Police were called to the hospital. Russell was interrogated for hours and insisted he would never harm his son. He told investigators that he may have “jostled” Alex when he tried to revive him.

After extensive treatment, Alex was discharged from the hospital. He was separated from his parents and a judge placed him into special-needs foster care. Kaye said she was told she could see her son only once every two weeks for an hour.

"I carried him in my womb for all those 34 weeks," Kaye Maze recalled of her son, Alex, who was born prematurely.


“It feels like I have lost a part of my soul,” she recalled of that time. “He’s no longer there. I carried him in my womb for all those 34 weeks. For me to have to give him up almost immediately was just unbelievable.”

That June, the Mazes were placed in handcuffs. A grand jury had indicted Russell on a charge of aggravated child abuse and Kaye on a charge of aggravated assault after prosecutors alleged that she knew about the bruises but failed to protect her son.

Kaye was placed on probation after she accepted the plea deal. She said she was told that would help her get her son back, but he remained in foster care. The family never reunited: Alex’s health declined rapidly in October 2000, and he was removed from life support over the Mazes’ objections.

Alex Maze's health deteriorated in October 2000 and he was taken off life support. He died at 19 months old.


Maze was taken from prison to the hospital room, but he remained shackled and could not touch his son or kiss him goodbye, Kaye recalled.

She insisted on a white casket for the funeral. Alex was dressed in overalls and tennis shoes, his fragile frame hugged by his favorite stuffed animals. A family friend played the bagpipes at his gravesite. Russell was not allowed to attend.

“He’s alone and without his mother. Without his father,” said Kaye, who felt as if she were abandoning her son as she walked away from his grave.

Upon the boy’s death, prosecutors sought a new charge against Russell Maze: first-degree felony murder.

In 2004, a jury found him guilty. The evidence at his trial included the autopsy conducted by Levy, who as the prosecution’s lead forensic witness testified that Alex’s death was a homicide, a direct result of the “shaken baby” diagnosis from 1999.

Brian Holmgren, the prosecutor who took Maze to trial, was previously on the advisory board of the National Center on Shaken Baby Syndrome, an organization dedicated to educating people about the diagnosis. He says that he and the jury got it right and that Maze should remain in prison. Anyone who disagrees “clearly did not understand what the heck they were talking about,” he told NBC News.

Brian Holmgren, a former Nashville prosecutor, took Russell Maze to trial and stands by the first-degree felony murder charge.


But in 2023, nearly two decades after Maze’s conviction, Sunny Eaton decided that his case deserved a second look. Eaton, a former public defender, leads the conviction review unit in the Nashville district attorney’s office, reopening cases in which people were found guilty but may actually be innocent. The “shaken baby” diagnosis gave her pause.

“I am a firm believer that whenever you have scientific testimony that has put someone in prison, we have to evaluate that scientific evidence and make sure that it still stands today,” she told NBC News. “The scientific evidence in this case was 25 years old.”

A New York Times Magazine/ProPublica profile last year highlighted how Eaton reinvestigated Maze’s conviction, bringing national attention to his case.

Over the course of nearly two years, Eaton said, her unit consulted more than a half-dozen experts to review the original findings. All of them said Alex’s death was most likely from natural causes, not abuse.

"This was not a healthy baby," Sunny Eaton, who leads the Nashville district attorney’s office's conviction review unit, said of Alex Maze.


Eaton said Starling, the child abuse pediatrician whose shaken baby diagnosis helped build the case, did not review Kaye’s pregnancy records and made her determination before many tests were conducted on Alex.

“This was not a healthy baby,” Eaton said, “and he was not a healthy baby even before he was born.”

Starling did not respond to requests for comment.

In March 2024, Eaton took her findings to court. The case landed before Davidson County Criminal Court Judge Steve Dozier, who had presided over Maze’s past trials and unsuccessful appeals. Eaton and Nashville District Attorney Glenn Funk asked for the Mazes’ convictions to be overturned. Several medical experts, including pediatric neurologists and radiologists “using current science,” concluded that Alex suffered from an undiagnosed medical condition, Funk said.

When one of the prosecution’s experts, a medical examiner, suggested that Levy, the original medical examiner on the case, would now agree that Alex died from natural causes, Dozier was skeptical.

“You are going to be able to say that ‘I can bring in the doctor who testified and did the autopsy and he’s going to admit he was wrong’?” Dozier asked.

The judge denied the Mazes’ attempt to dismiss their convictions.

Kaye was devastated.

“What is he losing by letting Russell go?” Kaye asked. “It’s not like he has not served 26 years already.”

Dozier declined to comment on the Mazes’ case but referred NBC News to his orders; in his ruling last year, he wrote that he was “unconvinced” by testimony from additional medical experts, which he categorized as merely “new ammunition in a ‘battle of the experts.’”

Not long after Dozier’s decision, Levy got a call from the medical examiner who had testified in the recent hearing, asking whether he would review his autopsy findings from decades earlier.

He was living in Pennsylvania, where he had moved to work for a hospital system. Since Alex’s death, he had learned more about shaken baby syndrome. He attended an abusive head trauma conference where he heard about brain injuries in the military and professional sports, widening his view of other possible causes of symptoms.

“I started realizing that some of the mechanisms that had been proposed early on with shaken baby syndrome, maybe we were a little bit too certain about them than we first thought, that maybe there are alternatives,” Levy said.

Levy said he revisited Alex’s case with an open mind. He reread the records and re-examined the slides of the boy’s brain. He also absorbed information he had not previously seen about Alex’s premature birth and racing heart. “That history should have been there” during his initial autopsy, he said.

He produced a sworn affidavit for Nashville prosecutors recanting his homicide finding and determining that Alex had succumbed to a “natural” death.

He ultimately could not say for sure what killed Alex, but he no longer thought the evidence pointed to abuse. He believed the Mazes were innocent.

But in October, the Tennessee Court of Criminal Appeals upheld Russell Maze’s conviction in a 2-1 ruling. The majority opinion brushed off Levy’s affidavit, finding it presented only a “bare allegation of a possibility” of a natural cause of Alex’s death.

“Dr. Levy’s changed opinion as expressed in his affidavit is merely a matter of witness recantation, rather than providing new scientific evidence of actual innocence,” they wrote.

Appeals court Judge Tom Greenholtz disagreed. He was swayed by Levy’s reversal, writing in a dissenting opinion that “the medical examiner’s recanting of his testimony establishing the cause and manner of death, separate from the reasons for the recantation, is itself the new scientific evidence warranting reconsideration.”

Maze, 60, has few options left. He could petition the Tennessee Supreme Court, although it is not guaranteed his case will be heard. He could also seek a pardon from Tennessee’s governor, who did not respond to requests for comment.

Kaye, 62, said that while she fights for her husband’s freedom, her anger also gives way to gentler moments, loving memories of Maze sweetly rocking Alex to sleep when the world revolved around her family of three.

“The bad thing is we are in our 60s now,” Kaye said. “We were in our 30s when this happened. So now we are closer to the end of our road. How much time we have left together, nobody knows.”

Levy remains hopeful the legal system can find a way to free Maze. He winced as he thought of his role in the case, how a couple has been separated through decades and how he believes an innocent man remains in prison.

“I would like Russell to come home,” Levy said. “I think he has paid a horrible price for mistakes that I and others have made.”

FINAL, FINAL WORD: "Since its inception, the Innocence Project has pushed the criminal legal system to confront and correct the laws and policies that cause and contribute to wrongful convictions.   They never shied away from the hard cases — the ones involving eyewitness identifications, confessions, and bite marks. Instead, in the course of presenting scientific evidence of innocence, they've exposed the unreliability of evidence that was, for centuries, deemed untouchable." So true!

Scott Watson: New Zealand: Flawed Forensics? Mike White, a consumate investigative reporter on New Zealand's criminal justice system, reveals a second forensic blunder' in the controversial case of Scott Watson, who has always denied murdering Marlborough friends Ben Smart and Olivia Hope, noting that: PHF Science, formerly ESR, has acknowledged that not only did a staff member’s eyelash end up among hairs taken from Watson’s yacht during testing in 2024, but tubes containing vital samples were handled in a non-laboratory environment, and touched by at least one staff member not wearing gloves. Watson was convicted of murdering friends Hope, 17, and Smart, 21, after a New Year’s party at Furneaux Lodge in the Marlborough Sounds in January 1998. Their bodies have never been found, and the case relied heavily on circumstantial evidence."


-------------------------------------------------------


BACKGROUND: From a previous post of this Blog: "The young friends had planned to sleep on the chartered yacht Tamarack but arrived to find the berths full. A man travelling alone on Guy Wallace's water taxi offered them a place to sleep on his yacht instead, and Wallace dropped the trio off about 4am. Wallace, who died in 2021, initially described the yacht as a wooden ketch with two masts - totally different to Watson's steel-hulled sloop, Blade. He also gave evidence  that Watson was the mystery man on his water taxi, but later recanted that testimony. At the 1999 trial, Wallace told the jury he had picked Watson out of a montage of photos  from police because he recognised his "hooded" eyes.  The "blink photo", as it became known, showed Watson with his eyes half-closed. Wallace later said police pressured him, and also admitted he may have been confused over the location of the yacht. Bar manager Ros McNeilly also identified Watson from a photo montage - but changed her mind after she saw a photograph of Watson on the night of the party. An inquiry by the Independent Police Conduct Authority in 2010 found the use of the photo montage was "problematic" and fell short of best practice. Two prison informants gave evidence at the trial that Watson had confessed to them. However, one later said he had lied under pressure, and it was revealed the other man had never shared a cell with Watson."


----------------------------------------------------------------



QUOTE OF THE DAY: Scott Watson’s father, Chris Watson, said it was ironic that, given ESR’s forensic testing of hairs from the tiger blanket had always been central to concerns about the case, further testing of the hairs had seen two mistakes exposed. “It’s starting to look like they’re pretty slap-dash in their dealings with exhibits.” Given the controversy around the original tiger-blanket hair testing, Chris Watson said it might have been expected ESR would do everything it could this time to avoid any criticism. “But they’re producing more concerns. The eyelash produced concerns - now this is even more.” Instead of validating the original testing, the latest tests had simply raised further questions, both in the contamination events, and the fact no DNA from Hope and Smart was found, Chris Watson said."


------------------------------------------


PASSAGE OF THE DAY: "The most crucial evidence against Watson was two hairs police said were found on a tiger-patterned blanket on Watson’s yacht, which analysis showed came from Hope. However, the testing of these hairs in 1998 was riddled with questions and controversy that hasn’t gone away, despite Watson’s conviction. Watson has always maintained his innocence, but remains in prison after more than 27 years. In the lead up to his latest appeal in 2024, police decided to try and bolster the forensic link between Watson, and Hope and Smart, and eventually spent more than $55,000 testing 30 other hairs from the “tiger blanket”. None showed any connection with Hope or Smart. But in July, the Sunday Star-Times revealed that during the recent DNA testing, a hair from an ESR scientist became mixed with the tiger blanket hairs and was analysed. It was an eyelash from the scientist that transferred to the sample when she took off her glasses to look through a high-power microscope. ESR notified police and the Crown of the error. However, the Sunday Star-Times can now reveal there was another forensic bungle during the testing process, which ESR had not previously acknowledged."


————————————————


PASSAGE TWO OF THE DAY: "When the hair samples that had been in storage were being sent from an ESR facility in Wellington, to Auckland for testing, the tubes they were contained in were emptied out of a self-sealing plastic bag in a non-laboratory environment. The tubes selected for testing were then taken to an office in preparation for sending to Auckland, but were then handled by at least one staff member not wearing gloves. While the tubes themselves had not been opened, concerns were raised that other DNA could be mistakenly transferred on the tubes, and once the errors were discovered, staff were forced to clean the tubes before testing commenced."

STORY: "Second forensic blunder revealed in Scott Watson case," by  Investigative Reporter Mike White, published by The Post, on December 13, 2025. (Mike White is a senior writer and columnist specialising in feature writing including criminal justice investigations.)


PHOTO CAPTION: "Scott Watson, who has always denied murdering Marlborough friends Ben Smart and Olivia Hope.."


GIST: "Further mistakes have been revealed in the testing of forensic samples at the heart of Scott Watson’s conviction for murdering Olivia Hope and Ben Smart.

PHF Science, formerly ESR, has acknowledged that not only did a staff member’s eyelash end up among hairs taken from Watson’s yacht during testing in 2024, but tubes containing vital samples were handled in a non-laboratory environment, and touched by at least one staff member not wearing gloves.

Watson was convicted of murdering friends Hope, 17, and Smart, 21, after a New Year’s party at Furneaux Lodge in the Marlborough Sounds in January 1998.

Their bodies have never been found, and the case relied heavily on circumstantial evidence.

The most crucial evidence against Watson was two hairs police said were found on a tiger-patterned blanket on Watson’s yacht, which analysis showed came from Hope.

However, the testing of these hairs in 1998 was riddled with questions and controversy that hasn’t gone away, despite Watson’s conviction.

Watson has always maintained his innocence, but remains in prison after more than 27 years.

In the lead up to his latest appeal in 2024, police decided to try and bolster the forensic link between Watson, and Hope and Smart, and eventually spent more than $55,000 testing 30 other hairs from the “tiger blanket”.

None showed any connection with Hope or Smart.

But in July, the Sunday Star-Times revealed that during the recent DNA testing, a hair from an ESR scientist became mixed with the tiger blanket hairs and was analysed.

It was an eyelash from the scientist that transferred to the sample when she took off her glasses to look through a high-power microscope.

ESR notified police and the Crown of the error.

However, the Sunday Star-Times can now reveal there was another forensic bungle during the testing process, which ESR had not previously acknowledged.

When the hair samples that had been in storage were being sent from an ESR facility in Wellington, to Auckland for testing, the tubes they were contained in were emptied out of a self-sealing plastic bag in a non-laboratory environment.

The tubes selected for testing were then taken to an office in preparation for sending to Auckland, but were then handled by at least one staff member not wearing gloves.

While the tubes themselves had not been opened, concerns were raised that other DNA could be mistakenly transferred on the tubes, and once the errors were discovered, staff were forced to clean the tubes before testing commenced.

Tanja van Peer, acting general manager of PHF Science’s Forensic Business Group, said the organisation took its responsibility to provide forensic services for New Zealand very seriously “and stands by the integrity of its processes and the professionalism of its staff”.

She stressed the two incidents were identified by staff, and didn’t affect the outcome of the testing.

The fact they were picked up was “a sign that our quality systems are working”, van Peer said.

When asked whether the mistakes should have happened in the first place, van Peer said in any highly technical scientific environment, avoiding contamination was a primary consideration, and they tried to minimise this through stringent anti-contamination protocols.

She stressed PHF Science was accredited to international standards, and underwent regular reviews and audits. However, it does not appear that PHF Science has reported the recent incidents to its accrediting body.

Scott Watson’s convictions for murder are among the most controversial in New Zealand history.

In the case of handling the sample tubes outside a laboratory and without gloves, documents obtained by the Star-Times under the Official Information Act show the cause was described as “Personnel/Inattention” by PHF Science.

“In retrospect, I should have searched for the required samples in the lab with full PPE (personal protective equipment),” one of the staff members involved stated.

“If I ever have to send samples like this again, I will be sure they are packaged in the laboratory first.”

In the documents, van Peer said staff involved with examining the hairs prior to the eyelash incident “took exceptional measures to mitigate risk, including tape-lifting themselves before proceeding on this work.

“It was simply an unfortunate incident.”

But prominent forensic scientist Anna Sandiford said describing the contamination event as an unfortunate incident was “inappropriate in a forensic setting”, and appeared to minimise the significance of the issue.

“Laboratory contamination is a defined quality-control failure, and its description should be factual and precise to accurately reflect its potential impact on the reliability of the results.”

However, she accepted the eyelash falling out during examination of the tiger blanket hairs could not reasonably have been anticipated, and the laboratory’s systems worked as they should in detecting that the DNA came from a staff member.

But Sandiford said handling sample tubes without gloves was a clear system failure.

It created the potential for contamination not only from staff DNA, but also from any biological material present on their hands or on surfaces contacted by the tubes. Any subsequent analyst handling the tubes could then have transferred this DNA further.

Given the sensitivity of current DNA testing, which could detect very small amounts of cellular material, Sandiford said contamination was expected occasionally, so strict adherence to handling procedures was essential.

And while the incident was dealt with appropriately by ESR, “it shouldn’t have happened in the first place,” Sandiford said.

Scott Watson’s father, Chris Watson, said it was ironic that, given ESR’s forensic testing of hairs from the tiger blanket had always been central to concerns about the case, further testing of the hairs had seen two mistakes exposed.

“It’s starting to look like they’re pretty slap-dash in their dealings with exhibits.”

Given the controversy around the original tiger-blanket hair testing, Chris Watson said it might have been expected ESR would do everything it could this time to avoid any criticism.

“But they’re producing more concerns. The eyelash produced concerns - now this is even more.”

Instead of validating the original testing, the latest tests had simply raised further questions, both in the contamination events, and the fact no DNA from Hope and Smart was found, Chris Watson said."

Watson has been in prison since 1998, and been rejected for parole four times.

His latest appeal was rejected by the Court of Appeal in September, with the three judges saying “the Crown presented a compelling circumstantial case to prove that only Mr Watson could have been the lone man who murdered Olivia and Ben.

“The evidence was carefully presented, challenged, and subjected to submission and analysis. It was a fair trial.”

In reaching its decision, the judges dismissed suggestions of mistakes by ESR in handling the hair samples in 1998, and that there could have been contamination of the two crucial hairs during DNA testing, saying this was “extremely unlikely”.

Following the Court of Appeal’s decision, Watson applied to the Supreme Court for leave to appeal there, and is currently waiting to see if this is granted.

Watson is due to have his next parole board hearing early in 2026."

FINAL, FINAL WORD: "Since its inception, the Innocence Project has pushed the criminal legal system to confront and correct the laws and policies that cause and contribute to wrongful convictions.   They never shied away from the hard cases — the ones involving eyewitness identifications, confessions, and bite marks. Instead, in the course of presenting scientific evidence of innocence, they've exposed the unreliability of evidence that was, for centuries, deemed untouchable." So true!
