Texas tampering with or fabricating physical evidence
Texas tampering with or fabricating physical evidence is a criminal offense under Penal Code § 37.09. Base conduct is classified as a third-degree felony; enhancements and aggravators can move the punishment range higher. Below: the controlling statute text, the full punishment range, common defense theories, and what to do if you have been charged in Collin, Dallas, Denton, or Tarrant County.
Classification: Third-degree felony (second-degree if human corpse)
Punishment range: Third-degree felony (2–10 years + $10,000) baseline; second-degree felony (2–20 + $10,000) when the evidence is a human corpse under § 37.09(c)
The controlling statute
Texas Penal Code § 37.09 punishes anyone who alters, destroys, or conceals any record, document, or physical evidence with knowledge that an investigation or official proceeding is pending or in progress. The statute is the workhorse of obstruction prosecutions — covering everything from deleting text messages during a DWI investigation to disposing of weapons after a shooting. When the evidence in question is a human corpse, § 37.09(c) elevates the offense to a second-degree felony, creating significant exposure for anyone who moves or conceals a body following any death.

Elements the State must prove
To convict on a Texas § 37.09 charge, the State must prove every element beyond a reasonable doubt:
- Defendant altered, destroyed, or concealed any record, document, or thing
- With knowledge that an investigation or official proceeding was pending or in progress
- With intent to impair its verity, legibility, or availability as evidence
- (For corpse enhancement) The physical evidence was a human corpse
Defense strategies
L and L Law Group, PLLC develops the following defense strategies on every Tampering with or Fabricating Physical Evidence case:
- Lack of knowledge that an investigation was pending or in progress at time of the act
- No intent to impair availability — routine document destruction or cleaning
- Constitutional challenges — destruction of one's own property may implicate Fifth Amendment self-incrimination protections
- Mistake of fact about the evidentiary nature of the item under § 8.02
- Suppression of evidence obtained during warrantless search that revealed tampering
- Timing — destruction before an investigation existed lacks the statutory mens rea
Enhancements & collateral consequences
Second-degree felony when the physical evidence is a human corpse under § 37.09(c) — a separate offense classification regardless of whether the underlying death was natural, accidental, or criminal. Parallel federal exposure under 18 U.S.C. § 1519 (Obstruction of Federal Investigation) is common when federal agents are involved. Multiple acts of tampering can be charged as separate counts.
Key Legal Terms
- Physical Evidence (§ 37.09(a))
- Any record, document, or thing — broadly includes digital data, photographs, weapons, biological samples, and any tangible item with evidentiary value.
- Corpse Tampering (§ 37.09(c))
- Second-degree felony for altering, destroying, or concealing a human corpse with knowledge of pending investigation; separate offense from underlying death.
- Knowledge of Investigation
- Subjective awareness that investigation is pending or in progress; preservation letters, subpoenas, or officer contact establish knowledge.
