There is no way to tell how many of the more than 1,450 people executed since 1976 may also have been innocent. Courts do not generally entertain claims of innocence when the defendant is dead. Defense attorneys move on to other cases where clients' lives can still be saved. Some cases with strong evidence of innocence include:
Carlos DeLuna: Texas — Conviction: 1983, Executed: 1989
