from www.abcnews.go.com – Neighbors of a Los Angeles man wanted for questioning in connection with the slaying of Ronni Chasen told ABC News today that he had bragged about killing the powerhouse Hollywood publicist.

“He was like, you know that publicist, I killed her,” said Terry Gilpin, 46, who lived in the same Beverly Hills apartment building as the man known to neighbors as “Harold.”

The suspect fatally shot himself Wednesday night at the Harvey Apartments on Santa Monica Boulevard in Hollywood as police closed in, authorities said. He was pronounced dead at the scene.

“While conducting that follow up, the person they were looking for showed up. They attempted to talk to the suspect. When they did, the suspect produced a hand gun and there was a self-inflicted wound at that point,” Los Angeles police captain Kevin McClure said.

Authorities have not confirmed the man’s identity and won’t say how the man might have been connected to Chasen’s death other than that he was a “person of interest.”

Gilpin, and her husband, Brandon Harrison, 27, described an altercation with Harold two or three weeks ago during which he made threatening statements and cited his purported role in the killing of Chasen.

Chasen, 64, who represented A-list movie stars and promoted some of Hollywood’s top films, was driving home Nov. 16 after attending the premiere party for the movie “Burlesque” when she was gunned down.

Police sources told ABC News that they plan to do a ballistics test to see if the gun used in the suicide is the gun used to kill Chasen.

Harrison told the Los Angeles Times that Harold described himself to a neighbor as “an ex-convict who served two stints in state prison, the most recent for firearms and drug convictions” and “vowed he would never go to prison.” He told the neighbor that he would be receiving $10,000, either for a job he had done or from a lawsuit.

Investigators have struggled to identify a motive or suspects in Chasen’s slaying. There were no witnesses. But an initial coroner’s report revealed that the shooter appears to be an expert marksman.

According to the coroner, “there were three apparent gunshot wounds to the right side breast/chest area. There were two apparent gunshot wounds to the right shoulder. There was an apparent gunshot wound to the right upper back and the left upper back.”

“One bullet was recovered from her back while at the hospital and is possibly a 9mm hollow point,” the report said.

Detectives suspect the gunfire came from a SUV or truck pulling alongside Chasen’s Mercedes Benz E530. Chasen was stopped at a red light Sunset Boulevard and Whittier Drive when the shooting occurred.

“After being struck by gunfire…she then made a left turn and drove for approximately a quarter mile before she crashed her car into a pole,” the report said.

Detectives say it appears the shooter was an expert marksman.

“Normally they turn the gun sideways and this is something that was done with some skill,” said Gill Carillo, who worked as a homicide detective in Los Angeles for more than 20 years. “I carried a gun for 38 years and had to fire it quarterly. I don’t think that I could shoot and hit that mass like that.”

No shell casings were recovered and only the car’s right side passenger seats and windows were damaged.

Investigators told ABC News that the security cameras that used to monitor traffic at the intersection where Chasen was shot were removed several years ago to save money.

However, Beverly Hills police are seeking for any surveillance video that may provide more clues in solving Chasen’s murder.

On Nov. 18, The Hollywood Reporter, cited an unnamed Beverly Hills official who said police believed the attack “was planned in advance and not the result of road rage or a carjacking gone awry.”

The Reporter’s website also said there was “relevant footage” from at least one security camera near the site of the shooting.

The trade paper reported the video came from the home of Sherry Hackett, widow of the late comedian and actor Buddy Hackett, who lived down the block.
