Authorities believe they have determined a suspect in the 1974 murder of Alice Police Officer Matthew Murphy.
Police now suspect 70-year-old Roberto Lopez in the killing. Alice Police Chief Rex Ramon served Lopez with an arrest warrant Wednesday night.
According to the arrest affidavit, Lopez reportedly bragged while in prison about shooting and killing a "narc" named Murphy with a .22-caliber pistol.
Jail officials in Alabama said Lopez is a prisoner there serving a life sentence without parole.
