Inculpatory evidence

'Inculpatory evidence is evidence that shows, or tends to show, a person's involvement in an act, or evidence that can establish guilt.

According to the 1963 Supreme Court decision in Brady v. Maryland, the prosecution has a duty to provide all evidence to the defense, whether it favors the prosecution's case or the defendant's case. Evidence that tends to show a person's innocence is considered exculpatory evidence.

For example, if a man is poisoned to death by an overdose of arsenic, and a bottle of arsenic is found in the purse of his wife, that bottle could be considered inculpatory evidence against his wife.
