Houston DWI Lawyer - What the Harris County Toxicologist Firing Means for Houston DWI Cases

A surprising story broke recently in Harris County: a toxicologist named Cassandra Cavazos-Johnson was fired in January 2025 for being untruthful, according to a Click2Houston report. Her job involved testing evidence for over 1,200 court cases, including many DWI charges in Houston. This news has big implications for people facing these charges, and it’s something a Houston DWI lawyer can use to ensure a fair trial. Let’s explore how this situation might affect jury selection and questioning experts in court, all with the goal of finding the truth—whether that leads to a guilty or not guilty verdict.

The Story: What Happened?

Cassandra Cavazos-Johnson worked at the Harris County Institute of Forensic Sciences, analyzing evidence like blood tests for DWI cases and drug screenings. She was let go after reportedly altering a document related to her license renewal, raising questions about her honesty. Now, the Harris County DA’s Office is reviewing cases she worked on from 2019 to early 2025 to see if her involvement affects their outcomes. For anyone charged with a DWI in Houston, this could mean a second look at their case—and a Houston DWI lawyer can help make sure justice is served.

Jury Selection: Finding Fairness

When someone’s charged with a DWI, their trial starts with picking a jury. This process, called voir dire, is all about finding people who can weigh the evidence fairly. The toxicologist’s firing gives a Houston DWI lawyer a chance to talk to potential jurors about how they view scientific evidence, which is often a big part of DWI cases. Here’s how it might go:

• Understanding Evidence: A lawyer might ask, “How do you feel about relying on lab results in a trial? What if there’s a chance they’re not perfect?” This helps find jurors who are open to looking at all sides of the story.

• Real-Life Mistakes: Another question could be, “Do you think people in important jobs can make mistakes? How would you handle that in a trial?” It’s a way to see if jurors can think critically about evidence without assuming it’s always right.

• Keeping an Open Mind: A lawyer might also ask, “If you heard someone made an honest mistake—or even lied—would you still listen to all the evidence fairly?” This ensures the jury won’t just side with the prosecution because of a badge or a lab coat.

The point isn’t to trick anyone—it’s to build a jury that’s ready to dig into the facts and decide what’s true, which might mean a not guilty verdict if the evidence doesn’t hold up.

Questioning Experts: Getting to the Truth

In DWI trials, the prosecution often brings in experts—like other toxicologists—to explain test results, such as blood alcohol levels. With Cavazos-Johnson’s firing, a Houston DWI lawyer can ask questions to make sure those results are solid. Here’s how they might approach it:

• Checking the Process: A lawyer could ask, “Can you explain how evidence is handled in your lab? Are there safeguards to prevent mistakes?” This ensures the jury knows whether the system is trustworthy.

• Learning from the Past: They might also say, “How was your team trained to avoid errors like what happened with Ms. Cavazos-Johnson?” It’s a fair question to see if the lab has cleaned up its act.

• Making Sure It’s Reliable: If the expert’s work connects to Cavazos-Johnson’s, a lawyer might ask, “Did her results ever affect yours? How do we know yours are accurate?” This isn’t about accusing anyone—it’s about confirming the evidence stands on its own.

  
  

These questions help the jury see the full picture. If the answers hold up, the prosecution’s case might stand. If not, it could lead to a not guilty verdict—exactly what a fair trial is supposed to figure out.

Why This Matters for Houston DWI Defendants

DWI cases in Houston often come down to science—breath tests or blood samples that seem like slam dunks. But when someone like Cavazos-Johnson, who handled that science, gets fired for dishonesty, it’s a reminder that evidence isn’t always perfect. For defendants, this could mean a chance to challenge their charges, especially if her work was part of their case. A Houston DWI lawyer can use this to push for fairness, whether that’s getting a case re-examined or fighting for a not guilty verdict in court.

Wrapping Up: A Chance for Justice

The firing of a Harris County toxicologist isn’t just drama—it’s a wake-up call about how important it is to get things right in DWI cases. A good Houston DWI lawyer can use this in jury selection to find fair-minded people and in court to double-check the evidence. The goal? A just verdict, whatever that may be. If you’re facing a DWI charge in Houston, this could be your shot at making sure your side of the story gets heard. Talk to a lawyer who knows how to navigate this—it might make all the difference.
