The Father's Day Bank Massacre was a bank robbery and shooting that took place on Sunday, June 16, 1991, at the United Bank Tower (now the Wells Fargo Center) in Denver, Colorado. The perpetrator killed four unarmed bank guards and held up six tellers in the bank's cash vault. An estimated $200,000 was stolen from the bank. Nearly three weeks later, on July 4, 1991, authorities arrested retired police officer James W. King for the crime. The subsequent trial was broadcast nationally on Court TV. After days of deliberation, the jury acquitted King. None of the stolen money was ever found. The crime remains unsolved and is considered a cold case.
