What’s Under Review at the Crime Labs

Issue No. 1 | July 31, 2026 Meeting | Q3 Docket

The Texas Forensic Science Commission Dispatch is our quarterly read on what Texas crime labs disclosed, what complaints were filed, and what rules changed, translated into what it means for a Dallas-Fort Worth defense. The Commission meets four times a year. Each issue covers the newest docket and, starting with the next one, closes the loop on the issue before it.

This first issue covers the docket from the Commission’s July 31, 2026, meeting. Four times a year the Commission publishes a docket of the crime-lab problems Texas labs are legally required to report, along with every outside complaint. The July agenda included a new DNA self-disclosure from the Dallas County crime lab (SWIFS), a firearms complaint against the Tarrant County Medical Examiner, a blood-alcohol complaint against a Houston lab, and a proposed rule that would let the Commission punish labs that skip the state’s new records portal.

What the Forensic Science Commission Actually Does

The Texas Legislature created the Commission in 2005, and its authority sits in Article 38.01 of the Code of Criminal Procedure. Nine members appointed by the Governor run it, seven scientists and two attorneys, one prosecutor and one defense lawyer. The Commission accredits Texas crime labs, licenses forensic analysts (a requirement since January 1, 2019), and investigates allegations that a lab committed professional negligence or professional misconduct serious enough to affect the integrity of a result.

Two features make its work useful to the defense. First, Texas law requires labs to self-disclose their own significant problems, so many entries on the docket are confessions the lab had to file. Second, the Commission publishes final investigative reports, which become public records a defense lawyer can cite. And accreditation is not cosmetic. Under Article 38.35, forensic analysis and the expert testimony tied to it are not admissible in a criminal case if the lab was not accredited at the time of the analysis.

What Was on the July 31 Docket in DFW

A note on timing first. The items below were on the Commission’s July 31 agenda. Its formal votes will appear in the minutes adopted at the next quarterly meeting on October 23, and final reports publish only after they are adopted. Treat these as what the Commission took up, with the official outcomes to follow in the next Dispatch.

A New DNA Self-Disclosure from the Southwestern Institute of Forensic Science (SWIFS)

The docket lists a new forensic biology and DNA self-disclosure from the Southwestern Institute of Forensic Sciences, the Dallas County crime lab, numbered 26.19. The agenda does not describe its contents. What gives it weight is the backdrop. At the Commission’s January 2026 meeting, the same lab disclosed that one of its analysts had manipulated an electropherogram printout, the visual output of a DNA test, to conceal a contamination event. The analyst admitted it and was terminated in October 2025, and the lab reanalyzed cases where that was necessary. Now the same lab is filing another DNA disclosure. Two data points at one lab is a pattern worth asking about, and the lab has older history as well, including a 2021 final report on one of its firearms examiners.

A Firearms Complaint Against the Tarrant County Medical Examiner

Complaint 26.49 targets the firearms and toolmarks unit of the Tarrant County Medical Examiner’s Office. Firearms identification, the practice of declaring that a particular gun fired a particular bullet or casing, is one of the least validated forensic disciplines, a point the National Academy of Sciences and the President’s Council of Advisors on Science and Technology have both made. We walk through why in our post on ballistics matching. A pending Commission complaint against the very unit that may have handled your case is exactly the kind of fact a defense lawyer wants in hand.

A Blood-Alcohol Complaint, Which Matters in DWI

Complaint 26.22 is against the Houston Forensic Science Center’s toxicology unit, specifically blood alcohol. Blood-alcohol testing lands on this docket too. The Commission’s jurisdiction covers toxicology and blood alcohol the same way it covers DNA and firearms, so the same disclosure-and-complaint machinery is available when a DWI blood result is in doubt.

A Houston Firearms Report Up for Adoption

The Commission was also set to adopt the final investigative report in complaint 25.77, brought by the Federal Public Defender’s Office against the Houston Police Department and Houston Forensic Science Center firearms unit. As of this writing that report has not been posted, so its findings are not yet public. When it is published it becomes a citable document on the reliability of that unit’s work, and reports like it often travel well beyond the single case that produced them.

A Garland Lab Names an Isomer It Cannot Measure

The quarterly docket is not the only place these problems surface. In early July 2026, a quality incident at the Texas Department of Public Safety’s Garland Crime Laboratory put the same reliability issue in sharp relief. A forensic scientist there received an unsatisfactory proficiency test result after reporting a finding the data could not support. The analyst identified a compound and then designated its optical isomer as dextromethorphan. The problem is that the Garland lab does not have the instrumentation to determine a compound’s optical isomer at all. Per the lab’s own incident report, the result should have been reported as no controlled substance, or as methorphan with a note explaining that limitation. The reference is DPS Garland Lab Quality Incident Report QI-GAR-2026-0703-SD.

Why does one word matter that much? Because methorphan comes in two optical isomers that are chemically almost identical and legally worlds apart. Dextromethorphan is the over-the-counter cough suppressant, and Texas excludes it by name: Health and Safety Code Section 481.002(30) removes the dextrorotatory isomer of 3-methoxy-n-methylmorphinan and its salts from the definition of an opiate, which is the definition Penalty Group 1 runs on. Levomethorphan is Penalty Group 1 under Section 481.102(4), and Schedule II federally, and the racemic mixture of the two is treated the same way in both. A lab that cannot tell the isomers apart cannot tell a cough-medicine ingredient from a Penalty Group 1 controlled substance. Designating either one, when the instrument cannot see the difference, is a result unsupported by the data, which is why the proficiency test was marked unsatisfactory.

It is worth being straight about which direction this particular error ran. The isomer designated was dextromethorphan, the lawful one, so the mistake pointed toward no controlled substance rather than toward a charge, and the laboratory’s own quality system caught it and wrote it down. That does not make the problem smaller. An instrument that cannot resolve an optical isomer cannot resolve it in either direction, and the next report out of the same workflow is under no obligation to err in the defendant’s favor. The flaw is not which isomer was named. It is that an isomer was named at all.

This is the same problem we cover for stimulants in our post on l-methamphetamine versus d-methamphetamine. The lesson holds across drug classes. When the State’s lab reports a specific optical isomer, the first question is whether the instrument in that lab could actually determine it.

Why a Lab Disclosure Can Open a Discovery Door

A self-disclosure or a complaint is not just news. It is leverage. When a lab admits a problem, or the Commission opens an investigation, that fact can trigger obligations and unlock records in your own case.

It can be Brady material. The prosecution has a constitutional duty to disclose evidence favorable to the defense, and that includes impeachment. A documented problem affecting the analyst who worked your case, or the method used on it, is impeachment evidence. It also drives discovery. The Michael Morton Act, Article 39.14 of the Code of Criminal Procedure, lets the defense demand far more than the one-page report: the analyst’s bench notes, the validation records for the method, corrective-action files, and the self-disclosure itself. And it can reach a closed case. Article 11.073, the junk-science writ, provides a post-conviction path when the science has changed or a method is shown to be unreliable.

The theme underneath all of this is that accreditation is not oversight. A lab can be fully accredited and still employ an analyst who is falsifying data, because accreditation checks systems, not every individual result. We cover how that plays out in our post on how forensic misconduct unravels a conviction.

CLR Connect and the New Enforcement Teeth

Until recently, getting those lab records depended heavily on where your case was filed. A discovery request for a DWI blood test analyzed at a state lab but prosecuted in one county could run through a different process than the same request in another county. CLR Connect is meant to end that.

CLR Connect is a statewide crime-lab records portal created by Senate Bill 991 in 2023 and codified at Government Code Sections 411.161 through 411.164. The Department of Public Safety operates it, the operational rules sit in Title 37, Chapter 28, Subchapter N of the Administrative Code, and the rollout was set for August 2026. Every crime lab that performs forensic analysis for a Texas criminal case, as defined by Article 38.35, is required to participate, and participation is tied to the Commission’s accreditation framework. We explain the mechanics in detail in our CLR Connect post.

What was new on the July docket is the enforcement piece. The Commission took up its own disciplinary rule, a proposed new Subchapter G, that would authorize it to sanction a lab that fails to participate in CLR Connect, under the authority of Government Code 411.163(b). A portal only helps the defense if labs actually use it. Discipline for skipping it is what gives the mandate teeth, and it matters most in the highest-volume categories, DWI blood and DNA.

Two More Rule Changes Worth Watching

The same agenda carried two rule changes that point in opposite directions. The Commission considered lowering the required work experience for firearms and toolmarks examiners from five years to three, in order to qualify for a waiver of certain coursework or education requirements. In a discipline already criticized for weak scientific foundations, loosening the experience requirement is a development the defense bar should track. On the other side of the ledger, the Commission also moved to clarify that a licensed analyst must communicate honestly and fully with every party, including the Commission itself, a rule that reads like a direct response to the concealment problem that surfaced in Dallas.

What This Means If You Have a DFW Case

• If your case involves DNA from the Dallas County lab or firearms work from the Tarrant County Medical Examiner, ask whether a disclosure or complaint touches your analyst, method, or time period.
• Do not settle for the one-page lab report. Use the Michael Morton Act to demand bench notes, validation records, corrective-action files, and any self-disclosure.
• Treat accreditation as a floor, not a guarantee. A lab can be accredited and still have produced a bad result.
• On a DWI blood or DNA case, CLR Connect is about to make these records easier to obtain. Ask for them early.

The Commission’s docket is one of the few places where crime labs have to show their problems in public. Reading it is not idle curiosity. It is where a real forensic defense begins.

Next in the Dispatch: The Commission’s next quarterly meeting is October 23, 2026. Issue No. 2 will cover that docket and report what became of the items above, including whether the CLR Connect enforcement rule was adopted, what the Houston firearms report found, and whether the Dallas and Tarrant County matters went to investigation.
