Ronni Chasen Update: Gun Used by Suspect Not Likely Connected to Publicist's Death

LOS ANGELES (CBS/AP) The man dubbed a "person of interest" in the baffling murder of Hollywood publicist Ronni Chasen killed himself as police attempted to speak with him, but the gun he used in the suicide doesn't match the bullets used to kill Chasen after her death, according to a law enforcement official.

An initial coroner's report stated , obtained by local station KTTV, said one 9mm bullet was pulled from Chasen's back in the hospital, and the 64-year-old had been shot multiple times.

But according to a source close to the investigation, who spoke on the condition of anonymity, the gun Smith used to kill himself was a revolver and while they did not say what caliber the gun was, they did say it was not a 9mm.

Harold Martin Smith died Wednesday as Beverly Hills police investigating Chasen's death, working off of an anonymous tip, went to speak with him at a rundown apartment building. He shot himself with a handgun as police approached him in the lobby.

Investigators last week called Smith a "person of interest" but stressed that it was not known if he was connected to the slaying.

Chasen's final autopsy report has not been released, and Beverly Hills police have said little about the investigation. Police spokesman Lt. Tony Lee said his department would not be releasing any ballistics information for now.

At least one resident of the apartment building where Smith shot himself told reporters that Smith had bragged about the killing, though others thought he had mental issues and could not have carried out the homicide.

Chasen, 64, was gunned down in the early morning hours of November 16 as she waited to turn left from Sunset Boulevard onto Whittier Drive, apparently heading home after attending a premiere celebration of the new Cher film "Burlesque".
