Little information is known about the murder of Hollywood publicist Ronni Chasen. She was gunned down on Sunset Boulevard early November 16th, just minutes after she left a star-studded party to celebrate the premiere of the movie "Burlesque," police said.
After a person of interest killed himself, the gun used in the suicide is not a match to the gun used to murder Chasen. William Bratton, former L.A. police chief and former NYC police commissioner spoke to American Morning about the mysteries of the case Monday.
