Reports of the police using deception during interrogations are not uncommon. These include lying about possessing nonexistent evidence linking the suspect to the crime; claiming an accomplice/co-defendant has already confessed and implicated the suspect; claiming they have an eyewitness who saw the suspect commit the crime, and so forth.
Officers do this to overcome resistance and secure confessions. But is it legal? Can the police use deception during an interrogation in Texas?
They are generally allowed to do so
The landmark U.S. Supreme Court case Frazier v. Cupp (1969) established the federal standard permitting police deception during interrogations. In this case, the interrogating officer told Frazier that his cousin, who was a co-defendant, had already confessed to the crime and implicated him in the crime as well. Believing the lie, Frazier began talking and provided incriminating statements and a written confession, which led to a conviction.
The U.S. Supreme Court ruled on appeal that while the police officer’s deception was a relevant factor, it was not enough by itself to make an otherwise voluntary confession inadmissible.
Texas courts follow this standard. Police generally may use verbal lies or misrepresentations about evidence to prompt a response, provided the deception did not make the confession legally coercive or violate other criminal laws.
However, Texas courts prohibit fabricating physical evidence, such as fake physical documents or fabricated lab reports. In the Wilson v. State case, the San Antonio Court of Appeals suppressed the confession and reversed the conviction because a detective created a false crime lab report. The Texas Court of Criminal Appeals affirmed the appellate ruling because the officer tampered with evidence.
