Defenses for Intoxication Manslaughter in Texas

There are several potential defenses for an allegation of intoxication manslaughter in Texas.


Under the Texas Penal Code, a defendant may only be convicted for intoxication manslaughter if there is a causal connection between their behavior and the death of another person. This means that before they can be convicted, the prosecution must prove beyond a reasonable doubt that it was their actions—and not any other intervening cause—that directly caused the death of another individual.

In some cases, the services of a crash reconstruction expert can help show that there was a lack of causation. Such experts are typically hired to assess the scene of an accident, analyze evidence such as skid marks and other physical damage, and use their experience to build a case for or against causation.

Crash reconstruction experts may also offer testimony in court regarding the circumstances surrounding the incident. This can be helpful if there is any doubt about whether the defendant’s actions caused the death of another person. Ultimately, their expertise can be invaluable in determining whether intoxication manslaughter charges should stand.

Blood Testing

When a death has occured and intoxication is suspected on part of one of the drivers, law enforcement always make sure they get evidence of that drives level of intoxication. The most common way to do this is by testing a sample of a person’s blood for its BAC level; rarely will law enforcement seek a breath test when a death is involved.

However, there are a number of ways in which an experienced defense attorney can challenge a BAC test result. These include: questioning whether samples were taken and stored according to protocol; how long was the delay between the crash and the time the blood was drawn; challenging how accurately the test results were reported by the laboratory; raising concerns about whether the equipment used was properly calibrated; and examining records related to the chain of custody of any samples taken.
