Dallas police have suspended their investigation of former Cowboys' receiver Michael Irvin's report that a man flashed a gun at him at a stoplight.
Investigators said Wednesday they have hit a dead end because Irvin never returned their telephone calls.
Irvin has said he was stopped at a red light Jan. 12 when two men in a truck pulled up next to him and one of them flashed a gun.
