Authorities in Texas have several common methods of trying to determine whether or not you have been driving drunk. You may already be aware of some of them, such as the breathalyzer test or the field sobriety test. However, the evidence that law enforcement can gather and use against you is not limited to these assessments. At Oliva, Saks, Garcia & Curiel, we are aware that law enforcement can collect more evidence at the scene and send it to the crime lab at the Department of Public Safety for analysis. Due to advanced scientific techniques, the results from the crime lab can provide compelling evidence against you in court.
You may not be in any condition to perform field sobriety tests due to injury sustained in an accident. If that is the case, authorities can collect a blood sample using special tubes that they carry with them for this express purpose. According to ABC 7 Eyewitness News, forensic scientists then test the blood sample using a specialized machine to determine blood alcohol concentration.
Not only can scientists determine your blood alcohol level in this way, they may also be able to refute any statements that you have made about the number of drinks that you had. One of the scientists claims to be able to calculate the number of drinks you had based on your blood alcohol concentration. If it is higher than what you told authorities, it may cause you trouble in court.
If there is a question as to who was driving at the time of a DWI accident, forensic scientists may be able to make a determination by collecting DNA samples from inside the car and analyzing DNA found on the airbag or the steering wheel. Again, if what the DNA evidence shows is different than what you told authorities, that could ultimately hurt your case.
Nevertheless, even in the face of compelling evidence, conviction is never a foregone conclusion in a DWI case. More information is available on our website.
