Various Clients & Their Cases


State of Texas v. M. Chavez


Client stopped for speeding. Cop smells alcohol, and client admits drinking. Cop says Client failed field sobriety tests, and Client is arrested. Cop offers Client a breath test, and the breath machine detects an “interferent” and will not provide a breath score. Cop has Client’s blood drawn. Client’s BAC is supposedly 0.17%, and a prosecution expert predicted Client’s peak alcohol concentration would have been 0.20%–almost two-and-a-half times the legal limit in Texas! The jury found my client NOT GUILTY after only 20 minutes of deliberation.

Case Overview

The key to this case was the cop's treatment of the blood sample after my client was arrested. He filed paperwork claiming that he had immediately submitted the blood sample to a lab. However, I obtained additional video from the cop's in-car camera showing the cop making another DWI arrest right outside the jail after booking my client in. The truth was the cop turned my client's blood in at the end of his shift several hours later. The prosecution brought in 2 experts who testified that refrigeration was not necessary for a properly-sealed blood vial. It was not enough to overcome the video of my client performing the field sobriety tests almost perfectly. The jurors said after the trial that there was just no way someone could have such a high BAC and look that sober, and they didn't trust the accuracy of the blood sample given the way it was handled.

Outcome: Not Guilty
