An alibi is a form of evidence used to defend against a criminal charge by demonstrating that the accused was somewhere other than the scene of the crime when the crime was committed.
In Washington State, as in other jurisdictions, an alibi is a defense strategy used in criminal proceedings where the defendant aims to prove that they were in a different location at the time the alleged crime was committed, and therefore could not have been involved in the crime. The alibi defense is supported by evidence such as witness testimony, receipts, videos, electronic records, or any other documentation that can substantiate the defendant's claim of being elsewhere. Washington State courts require that the defendant notify the prosecution of their intent to use an alibi defense, along with the specific details of the alibi, including the place where the defendant claims to have been and the names of any witnesses who will corroborate the alibi. This is to ensure that the prosecution has a fair opportunity to investigate the alibi and prepare a response. The rules governing the use of alibi defenses in Washington are consistent with the constitutional right to a fair trial and the requirement that the prosecution prove the defendant's guilt beyond a reasonable doubt.
