On an early morning in March 1997, Angie Nihoff stops by to check on her grandma, Olga Parlante, known to all her friends as The Bingo Queen. Angie is horrified to find that Olga has been brutally beaten and isn’t moving. On a call to 911, a frantic Angie can't stop screaming, but some closest to Angie wonder if it is all an act. By the time detectives arrive on the scene, Olga has been pronounced dead. As detectives untangle a web of clues, they never find any concrete evidence tying Angie to the murder. Fifteen years later, detectives feed unidentified palm prints from the crime scene into a new advanced computer database. The prints match Bennie Hall, a burglar who is already in prison. Using this new evidence, Hall is convicted of Olga Parlante's murder and is sentenced to life in prison two decades after Olga’s death. But to this day some detectives still believe there may be a second murderer, who has never been caught.
