PASSAGE THREE OF THE DAY: "In Massachusetts, prosecutors are fighting a court’s ruling that tossed out James “Jimmy” Carter’s convictions for a deadly fire that killed 15 people, according to journalist Andrew Quemere, who has reported extensively on the case. After his appellate attorneys presented evidence that the State’s arson expert proffered testimony that has since been debunked, a Massachusetts judge vacated Carter’s convictions. Last year, he was released from prison after serving more than 36 years for a crime that may not have even occurred. Quemere reported that if the prosecutors win their appeal, Carter may have to return to prison, despite overwhelming evidence of his innocence."

SUB-HEADING: "Maria Montalvo was convicted of murder in 1996 after her children’s deaths in a fire, based on testimony from arson experts. In a petition for a new trial, her attorneys argue that the conviction rests on ‘outdated beliefs and junk science.’"
GIST: "Attorneys with the New Jersey public defender’s office are seeking a new trial for Maria Montalvo, a former nurse who was convicted of burning her children to death more than two decades ago. Montalvo’s attorneys argue that advances in forensic science have undermined the expert testimony that prosecutors relied on to secure her conviction.
Prosecutors accused Montalvo of intentionally setting a fire that killed 16-month-old Zoraida and 28-month-old Rafael. To support their case, the State proffered expert testimony that espoused the prevailing views of the day, but that her attorneys say has since been discredited.
In February, a New Jersey judge denied Montalvo’s petition, ruling that changes in fire science over the past 30 years did not constitute new evidence in the case. Montalvo’s attorneys are appealing the decision, which they say highlights the difficulty people face when challenging convictions based on junk science.
“There is a general belief that wrongful convictions are the problems of other prosecutors, other judges, other jurisdictions,” Deputy Public Defenders Tamar Lerer and Josh Hood said in a statement to The Appeal. “That belief is wrong. Wrongful convictions happen here because junk science happens here. Until we confront that reality, we will never be free of the harmful human cost that comes with relying on it.”
On the morning of February 22, 1994, Montalvo drove to see her estranged partner, Raul Aponte. Their two children were in the back seat. Aponte had moved out of their home and had been staying at his mother’s house in Long Branch, New Jersey.
Montalvo parked the car in front of the home and brought a bag of the children’s things —some clothes and a couple of bottles of milk—into the house and then returned to the car. At trial, Montalvo’s counsel told the jury that it was too icy to carry the children from the sidewalk to the home, so she drove around the block and pulled into the driveway.
Montalvo told police that she went to light a cigarette even though she smelled gas, and the car immediately burst into flames. When she struck the match, it ignited vapors that were escaping from a can of gas she had bought that morning and was by the front passenger seat, according to her lawyers. A neighbor said he saw Aponte pull Montalvo from the burning car.
Neighbors, emergency personnel, and Aponte tried to rescue Zoraida and Rafael, but, despite their efforts, both children died in the fire.
Prosecutors alleged that Montalvo, who had no history of child abuse, had doused the car with gasoline when she had purportedly driven away to move her car into the driveway. They say that when she returned, she stepped out and threw a match into the car, with her babies locked inside.
The day after the fire, on February 23, 1994, Montalvo appeared in court. Bandages covered her face, head, and one hand, according to photos published in the Asbury Park Press at the time.
Her trial began in November 1996. During the medical examiner’s testimony, the judge admonished her for sobbing and warned her not to have any more “outbreaks.”
There were conflicting eyewitness reports about where Montalvo was when the fire started—either in the car, as she said, or outside it, as the State alleged. Raul’s mother testified that immediately before the fire began, Montalvo exited the car and threw “something” onto the floor by the front passenger seat.
On cross-examination, the defense elicited testimony that she and Montalvo had an acrimonious relationship, attempting to cast her as a biased witness. The defense called a neighbor to the stand, who said that he saw Aponte “swing the car door out of the way and grab the woman.” He said that she “must have been in the car because he reached down and I saw him grab her.”
With the imprimatur of scientific objectivity, the State’s experts told the jury that, in effect, Montalvo’s version of events was implausible. Their testimony fit squarely with the State’s theory that Montalvo had leaned into the car and tossed what the prosecutor described as “something flaming” into the car.
They concluded that the fire began by the driver’s seat and, one expert said, no one in the car could have survived. (Their testimony conflicts with Raul’s mother’s claim that she saw Montalvo throw “something” on the floor by the passenger seat.)
V-type burn patterns “point down to where the fire originated,” testified Lt. Frederick Louis Dispensiere, an arson investigator with the Monmouth County Prosecutor’s office. “Some of these V patterns are not exactly the sharpest, straightest things, but to a trained investigator they are rather easy to discern,” he told the jury while referencing a photo of Montalvo’s car.
Despite the gravity of his testimony, Dispensiere’s description of their investigation seemed more akin to a late-night study session than a scientific inquiry.
“All of us got together in one corner of the garage,” he said. “We sat around and ate some pizza. Looked at the car, and we just discussed it. We just went around the group as a round table discussion, for lack of a better phrase, and everybody just voices their opinion as to what they thought actually happened. Where did the fire start? How did the fire start?”
A second expert, David Campbell, an arson investigator with the North Carolina Bureau of Investigation, testified that he, too, determined that the fire began around the driver’s seat based on V-type burn patterns, as well as Montalvo and Aponte’s mother’s statements. Campbell was adamant that anyone in the car would have died.
“There is not a chance that somebody could survive that,” he told the jury. “The person who lit the cigarette would perish where they are sitting.”
However, there have been numerous reports of people surviving fires in similar circumstances, and Montalvo’s appellate attorneys pointed out that Campbell had no medical training.
The experts’ testimony figured prominently in the State’s case.
“We know for a fact that no human being can outrun a gasoline fire,” the prosecutor told the jury during closing arguments. “We know for a fact that she wasn’t sitting in that car.”
The jury found Montalvo guilty on all counts. During the sentencing phase, Montalvo begged the jury to spare her life. The judge sentenced her to 100 years in prison after the jurors couldn’t unanimously agree to sentence her to death.
Twenty-five people have been exonerated of arson charges, according to the National Registry of Exonerations. Almost 70 percent of those exonerations occurred after Montalvo’s conviction.
The field of arson science has undergone a “revolution” since Montalvo’s conviction and the “evidence used to convict her has completely eroded,” her attorneys wrote in their petition for a new trial.
Fire investigators often misidentify the origin of a fire. A 2007 study found that fire investigators were more likely to incorrectly identify the origin of a fire, the longer it burned. In that study, investigators correctly identified the origin of a fire that burned 30 seconds past full room involvement, 84 percent of the time. But when examining rooms that burned 180 seconds past full room involvement, they correctly identified the origin just 25 percent of the time.
In 2021, a subcommittee of the Organization of Scientific Area Committees, established by the federal government’s National Institute of Standards and Technology, published a groundbreaking report declaring that “problematic myths” were persistent and widespread in the field of fire investigation. The experts in Montalvo’s trial appear to have based their findings on several of those myths.
Dispensiere, of the Monmouth County Prosecutor’s office, concluded that the fire originated in the area of the driver’s seat, in part, because that was the area that sustained the most damage. However, the government report says that the “origin will not necessarily be located where observable damage is most severe.”
“In a fully involved enclosure fire, the most intense burning occurs where fuel vapors encounter oxygen entering the fire enclosure, and that may not be where the fire originated,” the report said.
In Montalvo’s case, the fire encountered oxygen when the driver’s side door was opened, which may have led to the driver’s seat sustaining the most severe burns.
The State’s experts based their conclusions, in large part, on V-shaped burn patterns, but studies have revealed the fallibility of this method. A fire investigator’s ability to determine the origin of a fully-involved fire based exclusively on burn patterns “may be no better than random chance,” according to the government’s report.
In the 2024 edition of the National Fire Protection Association’s Guide of Fire and Explosion Investigations, the association cautions investigators “that a V shape is not necessarily associated with the origin of the fire” and can be created by, among other things, “combustion due to ventilation flow paths.” The 1995 edition, however, says that V-shaped patterns “can often be traced back from the higher to the lower levels, towards a point of origin,” according to Montalvo’s petition.
Despite these developments, in February, a Monmouth County Superior Court judge denied Montalvo’s petition for a new trial. She ruled that a jury could have found Montalvo guilty beyond a reasonable doubt even if they had not heard the expert testimony. To suggest that the fire was accidental is a “dishonor to the memory of those two children,” the judge wrote. Montalvo’s attorneys are appealing the decision.
The court’s denial illustrates the Sisyphean struggles people face when challenging convictions based on outdated science.
In Massachusetts, prosecutors are fighting a court’s ruling that tossed out James “Jimmy” Carter’s convictions for a deadly fire that killed 15 people, according to journalist Andrew Quemere, who has reported extensively on the case.
After his appellate attorneys presented evidence that the State’s arson expert proffered testimony that has since been debunked, a Massachusetts judge vacated Carter’s convictions. Last year, he was released from prison after serving more than 36 years for a crime that may not have even occurred. Quemere reported that if the prosecutors win their appeal, Carter may have to return to prison, despite overwhelming evidence of his innocence.
False or misleading forensic evidence has contributed to more than 1,100 known wrongful convictions, or more than a quarter of all exonerations, according to the National Registry of Exonerations.
“Though junk science is indisputably a leading cause of wrongful convictions, the system often ignores this reality when confronted with it in individual cases,” Montalvo’s attorneys told The Appeal in a statement.
In January, on his last day in office, Governor Phil Murphy granted Montalvo’s clemency petition, which made her immediately eligible for parole. The petition was filed on her behalf by the American Civil Liberties Union (ACLU) of New Jersey.
Earlier this month, a two-person panel of the parole board denied her application and barred her from reapplying for 18 to 36 months, according to the Asbury Park Press.
Aponte and the prosecutor’s office welcomed the parole board’s decision.
Aponte’s attorney, Meghan J. Doyle, told The Appeal that it was a “hollow victory” because “every 18 months he will have to relive it.” Doyle said she was a former prosecutor in the Monmouth County Prosecutor’s office. Although she was not with the office at the time of Montalvo’s trial, she said the prosecutor who tried the case was her boss when she worked in the office.
Doyle pushed back on the defense claims that the conviction was based on junk science.
“The pattern burning, if you just have that, you can’t really make a conclusion,” she said. “However, if you have an eyewitness saying, ‘This is what I saw, and this is what I watched,’ and the pattern burning matches that, they both corroborate each other. So to say it is just junk science, they are either making a misrepresentation or taking the studies so far out of context simply to get what they want.”
Monmouth County Prosecutor Raymond Santiago said in a statement that he was “elated” she was denied parole. Alluding to her innocence claim, he said, “releasing Maria Montalvo is incompatible with justice, especially for someone who refuses to fully accept their actions.”
Despite the recent setbacks, Montalvo’s attorneys remain undeterred in their fight to clear her name.
“Maria Montalvo has the right to a fair trial, grounded in reliable scientific evidence,” Lerer and Hood told The Appeal in a statement. “We reject the notion that a conviction based on bad science is justice and look forward to appealing the Court’s ruling.”

FINAL WORD: (Applicable to all of our wrongful conviction cases): "Whenever there is a wrongful conviction, it exposes errors in our criminal legal system, and we hope that this case — and lessons from it — can prevent future injustices."Lawyer Radha Natarajan: Executive Director: New England Innocence Project;
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."
