Faulty DNA tests: From our 'Here we go again?' department: A disturbing story from NPR - host Ari Shapiro - which I have not heard elsewhere in the media. HL) : "Faulty DNA tests being used in criminal cases in Texas could impact more than 1,000 cases as under some circumstances, these tests were incorrectly coming back as insufficient DNA to test."…"The Houston Forensic Science Center is reviewing hundreds of cases after it detected problems with Qiagen EZ1&2 Investigator DNA test kits. Center CEO Peter Stout says tests were coming back reading no DNA present when there was or that it was just one person's when sometimes it was from multiple people. PETER STOUT: It introduces a question mark that then the rest of the system has to try and figure out, OK, is this a case that was affected, and if so, what are we going to do about it? Do we need to retest it? FLAHIVE: The Texas Department of Public Safety is reviewing around 700 cases at just one lab. Qiagen is one of the big three manufacturers in the world of DNA tests. A Qiagen company spokesman told NPR they received less than 10 complaints in the U.S. about the tests. But the company declined to say the total number of potentially affected tests, so measuring the true impact of the issue has been difficult to determine. Experts say it's a national problem."


BULLETINS: TEXAS FORENSIC SCIENCE COMMISSION: 

Forensic Science Commission QIAGEN Issue Bulletin

In 2024, the vendor QIAGEN received feedback from a small number of customers regarding unexpectedly low DNA yields when using certain lots of their manufactured Cat. No. 952034 EZ1&2 DNA Investigator Kits (the “Kit”).  In March 2025, the Commission received a self-disclosure reporting the issue identified by a Texas laboratory. 

At the Commission's April 11, 2025 quarterly meeting, commissioner Erika Ziemak (Center for Human Identification) and the Texas Association of Crime Laboratory Directors President, Peter Stout (Houston Forensic Science Center), addressed the Commission to describe manufacturing issues identified by forensic DNA laboratories in Texas and nationally regarding QIAGEN's EZ1 and EZ2 investigator kits.

Following are the slides from the presentation:

QUOTE ONE OF THE DAY: "MICHAEL KESSLER: Texas is a death penalty state, many others are. Justice is a matter of life and death."

———————————----

QUOTE TWO OF THE DAY:  "FLAHIVE: Leaving many court cases in limbo as potential retesting is addressed. In a statement, Lisa M. Wayne, executive director of the National Association of Criminal Defense Lawyers, asked, how many lives have been upended? How many souls languish in prison because of compromised science?"

PASSAGE OF THE DAY: "STOUT: It's a big deal because this is a product that almost everybody uses all across the U.S., really, all across the world." FLAHIVE: Dan Krane is a professor at Wright University and runs the company Forensic Bioinformatics. He says retesting is necessary if there's enough to retest. DAN KRANE: A lot of these evidence samples are going to be, you know, swabs of gun cartridges, for instance, and they had one crack at it, and, you know, you just can't go back. FLAHIVE: The problem raises serious implications for the justice system. Michael Kessler of Kessler Forensic Solutions, which consults on court cases, says labs could lose evidence that proves the guilt or exonerates a criminal defendant."

POST: "Faulty DNA tests lead to more than 1, 000 criminal cases across Texas being reviewed," by Investigative Reporter (Texas Public Radio)  Paul Flahive.

GIST: "Faulty DNA tests being used in criminal cases in Texas could impact more than 1,000 cases. Under some circumstances, these tests were incorrectly coming back as insufficient DNA to test.

ARI SHAPIRO, HOST: 

More than 1,000 criminal cases across Texas may now have a question mark over them. The culprit? Faulty DNA tests. As Texas Public Radio's Paul Flahive reports, the tests were made by one of the biggest manufacturers in the world.

PAUL FLAHIVE, BYLINE: The Houston Forensic Science Center is reviewing hundreds of cases after it detected problems with Qiagen EZ1&2 Investigator DNA test kits. Center CEO Peter Stout says tests were coming back reading no DNA present when there was or that it was just one person's when sometimes it was from multiple people.

PETER STOUT: It introduces a question mark that then the rest of the system has to try and figure out, OK, is this a case that was affected, and if so, what are we going to do about it? Do we need to retest it?

FLAHIVE: The Texas Department of Public Safety is reviewing around 700 cases at just one lab. Qiagen is one of the big three manufacturers in the world of DNA tests. A Qiagen company spokesman told NPR they received less than 10 complaints in the U.S. about the tests. But the company declined to say the total number of potentially affected tests, so measuring the true impact of the issue has been difficult to determine. Experts say it's a national problem.

STOUT: It's a big deal because this is a product that almost everybody uses all across the U.S., really, all across the world.

FLAHIVE: Dan Krane is a professor at Wright University and runs the company Forensic Bioinformatics. He says retesting is necessary if there's enough to retest.

DAN KRANE: A lot of these evidence samples are going to be, you know, swabs of gun cartridges, for instance, and they had one crack at it, and, you know, you just can't go back.

FLAHIVE: The problem raises serious implications for the justice system. Michael Kessler of Kessler Forensic Solutions, which consults on court cases, says labs could lose evidence that proves the guilt or exonerates a criminal defendant.

MICHAEL KESSLER: Texas is a death penalty state, many others are. Justice is a matter of life and death.

FLAHIVE: The culprit for the faulty readings was tentatively identified as the pH balance of one of the chemicals used, the MTL buffer. Qiagen told clients it changed the manufacturing process to fix the issue, adjusting the amount and makeup of the chemical in the cartridge. But private lab Signature Science in Austin, that does testing in criminal cases, said in a letter obtained by NPR that Qiagen may not have identified all the affected kits, saying its testing was impacted into this year. For defense attorneys like Elizabeth Daniel Vasquez, there's a lot of unanswered questions on what happens now.

ELIZABETH DANIEL VASQUEZ: We're going to see a ton of cases where the impact of this is going to be directly clear. I think more likely what we'll see is a whole lot of lack of evidence that nobody realizes was lost in the process.

FLAHIVE: The work has just begun for labs across the country, says Peter Stout.

STOUT: It's going to fall on the labs to do the retesting. And no forensic laboratory in the country has the resources to keep up with just the work coming in the door, much less the rework potential and the audit that's going to come out of this.

FLAHIVE: Leaving many court cases in limbo as potential retesting is addressed. In a statement, Lisa M. Wayne, executive director of the National Association of Criminal Defense Lawyers, asked, how many lives have been upended? How many souls languish in prison because of compromised science?

(SOUNDBITE OF APHEX TWIN'S "ALBERTO BALSALM") many court cases in limbo as potential retesting is addressed. In a statement, Lisa M. Wayne, executive director of the National Association of Criminal Defense Lawyers, asked, how many lives have been upended? How many souls languish in prison because of compromised science?

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." So true!
