Police Working To Catch A Killer

Tulsa Police on Wednesday released a surveillance video in hopes of catching a killer.

The video shows a man in a white shirt.  Detectives say he may be responsible for Bayron Lopez's murder.

Lopez was followed after a fight at an east Tulsa bar Saturday.  He had driven a mile and a half from the bar when another car pulled up and he was shot in the chest near 36^th and Garnett.

Police believe Lopez was fighting with two men at the bar.  Alexander Lara is already in custody in connection with the murder.
