Causation Evidence in a Texas Manslaughter Case
Learn why a Texas manslaughter case requires a connection between the accused conduct and death, including competing causes and expert evidence.
In short: Texas manslaughter requires proof that the reckless conduct caused death. Penal Code 6.04 addresses causation, including concurrent causes. Another contributing event does not automatically eliminate liability, and temporal proximity does not by itself prove that the accused conduct caused the result.

Can more than one event contribute to a death?
Yes. Section 6.04 addresses conduct operating alone or with another cause and a specific limitation involving an independently sufficient concurrent cause and clearly insufficient accused conduct. That legal test requires more than identifying a second contributing factor.
What should an expert review address?
The appropriately qualified expert should evaluate records, the proposed mechanism and the limits of available data. Medical findings, reconstruction evidence and timelines answer different questions. An opinion should explain its reasoning rather than merely repeat a police conclusion.
How can a family help counsel?
Provide a chronological list of known events and the location of original records. Identify missing intervals without inventing explanations. Ask which causal link is disputed and what information could test it; do not contact treating professionals to pressure them into changing conclusions.
A practical example and questions for counsel
Hypothetical example: Suppose the prosecution identifies one act as causing death while the defense points to another contributing event. A useful review asks whether the proposed alternative is supported by records, how it operated and whether the statutory concurrent-cause limitation is actually implicated. Merely naming another possibility is not the same as testing it. An expert should be able to identify which records support the causal opinion and what information would change it. Counsel then connects that technical analysis to section 6.04 rather than treating the expert’s label as the legal conclusion.
How this fits Texas law
Penal Code 19.04 addresses recklessly causing another person’s death. Recklessness means conscious disregard of a substantial, unjustifiable risk, with the statutory gross-deviation requirement. Manslaughter is generally second degree; section 19.04(c) specifies a first-degree circumstance involving section 28.09. Both the mental state and causation deserve independent review.
