Most people assume a lab report is the end of the story in a criminal case… but is it?

If a sexual assault kit says “no male DNA detected” or a blood test says your alcohol level was over the limit, it can feel like the science already decided your future. Juries are told that forensic scientists are neutral, objective, and careful.

The “Missy Woods scandal” involving former Colorado Bureau of Investigation (CBI) forensic scientist Yvonne “Missy” Woods shows how fragile that trust can be. It also shows why you need a defense lawyer who understands the science well enough to check the state’s work instead of blindly accepting it.

Attorney Joe Maher, a Colorado Springs DUI and criminal defense lawyer, is one of a small number of attorneys in the country to earn the ACS CHAL Forensic Lawyer Scientist designation through the American Chemical Society. His practice is built around a simple idea. A lab report is not the final answer. It is evidence that can be tested and challenged.

This article walks through what is publicly known about the Woods investigation, why it matters even in cases that do not involve DNA, and how Joe’s scientific training helps protect clients when the lab gets it wrong.

Who Is Yvonne “Missy” Woods and What Is She Accused Of?

Yvonne “Missy” Woods worked as a forensic DNA analyst for CBI for nearly 30 years. She joined the bureau in 1994 and spent most of her career in the Jefferson County lab. In 2023, a CBI intern reviewing one of her cases noticed missing DNA data. That one question triggered an internal affairs investigation and outside review of her work.

According to publicly available CBI summaries and public reporting, investigators say Woods may have done the following in some cases.

• Manipulated DNA testing data by deleting or omitting values in the lab’s computer system
• Reran DNA batches without proper documentation
• Deviated from written testing protocols that are meant to protect the integrity of the evidence
• In some sexual assault cases, removed low level male DNA values and then reported “no male DNA detected”

CBI’s quality management team began by reviewing her work between 2008 and 2023. They first found hundreds of cases with potential problems. As the review widened, CBI reported 1,003 impacted cases statewide by December 2024 and later updated that number to 1,045 as of August 2025.

On January 22, 2025, the First Judicial District Attorney charged Woods with 102 felony counts, including cybercrime, first degree perjury, attempt to influence a public servant, and forgery. All of the charges are tied to her DNA work at CBI between 2008 and 2023. She was booked into the Jefferson County Jail on a fifty thousand dollar bond and is now awaiting trial.

Woods is presumed innocent unless and until proven guilty. Even so, the allegations have already shaken public confidence in Colorado’s forensic system.

How the Woods Scandal Is Impacting Real Cases

When a state scientist is accused of manipulating data in more than one thousand cases, it is not an abstract problem. It lands on real people.

CBI has committed to retesting hundreds of DNA samples and reviewing thousands of pages of casework. State leaders set aside about seven and a half million dollars to cover retesting and case reviews. That work has added to existing backlogs in sexual assault kit testing across Colorado.

Prosecutors around the state are reevaluating past convictions that relied on Woods’s DNA work. In 2025, for example, a Boulder County murder conviction was vacated after defense lawyers raised questions about her role in the DNA evidence. The district attorney is now deciding whether to retry the case with a new evidentiary record.

Civil rights groups have also questioned how long it took for the scope of the problem to become public and have raised concerns about victims and defendants stuck in limbo while the review drags on.

The fallout is still evolving. In February 2026, a Boulder County judge ordered CBI to provide access to thousands of DNA case files in the Michael Clark retrial after the defense argued Woods’ conduct may reflect a broader pattern, not an isolated mistake. That ruling matters because it shows courts are still wrestling with how far this scandal reaches and whether deeper institutional problems may have affected other cases as well.

If you are facing charges today, the message is simple. If alleged misconduct of this scale can happen in a high profile DNA unit, you should not treat any forensic report as unquestionable.

What Does a DNA Scandal Have to Do with DUI charges?

You might be thinking your case is a DUI, not a DNA case, so this has nothing to do with you. It does.

DNA and toxicology are different specialties, but they operate inside the same CBIFS system. The 2025 CBIFS audit describes high caseload pressure and a strong emphasis on productivity metrics, and notes that this pressure can compress training timelines and reduce thoroughness if not carefully managed.

Colorado has already seen serious problems in other lab units. In 2012, the state Department of Public Health had to retest about 1,700 DUI blood samples after a lab employee failed to follow required procedures. That mistake opened the door for defense lawyers to challenge blood test evidence in drunk driving cases across the state.

The point is not that every lab result is wrong. The point is that every lab result deserves scrutiny. Especially in a state where large groups of cases have already needed retesting.

How Joe Maher’s Forensic Lawyer Scientist Training Helps Check the Lab’s Work

This is where Joe Maher’s scientific background becomes important for your case.

To earn the ACS CHAL Forensic Lawyer Scientist designation, Joe completed intensive, hands on coursework in forensic chromatography, blood alcohol and blood drug analysis, and the science behind driving under the influence of drugs. He then passed a proficiency exam created by the American Chemical Society’s Chemistry and the Law Division.

In practice, that training helps him do things many lawyers are not equipped to do.

• Read and interpret raw instrument data, including chromatograms and calibration curves, instead of stopping at the final reported number
• Evaluate how sample collection, storage, and preparation may have changed blood alcohol or blood drug levels in a specific case
• Spot problems in chain of custody and quality control records that can undermine the reliability of a test
• Cross examine state lab analysts using their own methods, policies, and validation studies

In the shadow of the Woods scandal, this kind of questioning is not just helpful. It is necessary. When a lab analyst tells a jury, “I followed all of our protocols and this result is reliable,” Joe has the training to compare that statement to the actual data and the written procedures. That is the kind of careful review that might have exposed problems in the DNA unit earlier.

What To Do If You Think Your Case Might Be Affected

If you have received a letter saying your case may be impacted by the CBI investigation, or you simply do not trust the science in your case, do not ignore that feeling.

For older criminal cases that involved CBI DNA testing, a qualified defense lawyer can help you:

• Confirm whether Woods or the impacted DNA unit handled your evidence
• Obtain the complete lab file, not just a one-page summary
• Decide whether new testing, independent expert review, or a post-conviction motion makes sense in your situation

For current DUI or drug cases, your evidence may not involve DNA at all, but the same principles still apply. A Forensic Lawyer Scientist like Joe can:

• Request full discovery for your blood or breath test, including calibration records, instrument logs, and quality control data
• Review the chain of custody, storage conditions, and any reanalysis of your sample
• Work with independent experts when needed to retest or reinterpret the evidence
• Use scientific weaknesses in negotiations, pretrial motions, or trial to push for a better outcome

No lawyer can promise a specific result. Not every case will be dismissed because of lab problems. But you do not have to accept a government lab report as the final word in your future.

More to Come…

The Woods investigation is painful on many levels. Survivors of violent crime worry about whether their cases were handled correctly. People convicted on the basis of DNA evidence wonder if their trials were fair. The public is asked to trust a system that is now openly wrestling with questions about its own quality controls.

The answer is not to give up on forensic science. The answer is to demand better science and to insist that courts treat lab results like any other evidence. Something that must be tested, not automatically believed.

That is the approach Joe Maher and Maher and Maher Law bring to every DUI, drug, and criminal case they handle. By combining advanced scientific training with years of trial experience, they work case by case to hold government labs accountable and protect their clients’ freedom.

If you or someone you love is facing a DUI, drug, or other criminal charge in Colorado Springs or Southern Colorado, or if you believe your case may be affected by the CBI DNA scandal, contact Maher and Maher Law as soon as possible. Early involvement gives Joe a chance to preserve evidence, obtain the full lab file, and start the careful scientific review your case deserves.

Frequently Asked Questions

What is the CBI “Missy Woods” scandal?

The CBI “Missy Woods” scandal refers to allegations that former Colorado Bureau of Investigation DNA analyst Yvonne “Missy” Woods manipulated DNA test data, omitted results, and deviated from protocol in more than one thousand criminal cases between 2008 and 2023. She has been charged with 102 felony counts and is awaiting trial.

How could this scandal affect my Colorado criminal case?

If CBI performed DNA testing in your case, the results may need to be reviewed or retested. In some situations, courts are reconsidering convictions or sentences that relied heavily on Woods’s work because judges and prosecutors can no longer assume that the original lab results were accurate.

Does the Woods investigation change anything for DUI blood or drug tests?

The Woods investigation focuses on DNA, but it highlights bigger quality control issues in state labs. Colorado has already retested 1,700 DUI blood samples in a separate lab problem. That history is one reason defense lawyers now examine blood and drug testing procedures closely in every DUI case.

What can a Forensic Lawyer Scientist do that other attorneys might not?

A Forensic Lawyer Scientist has advanced training in the scientific methods used by crime labs. In Joe Maher’s case, that includes hands on coursework in forensic chromatography and blood testing plus a proficiency exam run by the American Chemical Society. That training helps him interpret raw data, question lab analysts effectively, and find scientific weaknesses that someone without that background might miss.

What should I bring to a consultation if I am worried about my lab results?

Bring any letters you received from CBI or the district attorney, copies of lab reports, charging documents, and any court paperwork you have. The more information your attorney has about which lab handled your testing and when, the easier it is to see whether your case might be affected and what steps to take next.
