L.A. Heat (1999) : 1x9

Arriving at the scene of a murder, Chase and August find that the victim is Bobby Roman, a favorite target of controversial shock-jock Jerry Maxwell. Roman has been shot in the head, just as Maxwell always advocated. When Chase and August confront Maxwell about the murder, the beligerent radio host denies involvement in the crime. But then a call comes into the station, and Maxwell is shocked to hear a devoted listener, Ward Valasco, claim that he killed Roman, and that he intends to kill all of Maxwell's enemies.
