Attorneys for a white Oklahoma police officer who killed an unarmed black man are asking in court records for investigators to keep as evidence a handgun that an anonymous tipster claims the man fired a day before the fatal shooting.

Tulsa police officer Betty Jo Shelby is charged with first-degree manslaughter in the Sept. 16 shooting of Terence Crutcher. Shelby shot Crutcher after arriving on a street to find Crutcher's SUV stopped in the middle of the road.

Defense lawyer Shannon McMurray says a man called claiming Crutcher was seen Sept. 15 walking down a different street and firing a gun, and that police recovered a gun left in the road.

Police declined comment Tuesday. They have said Crutcher had no gun on him or in his SUV when he was shot.
