Detectives investigating the murder of Hollywood publicist Ronni Chasen say she was probably shot from another vehicle, possibly an SUV, the Los Angeles Times reported.

Mayor of Beverly Hills Jimmy Delshad told the paper that police have no motive or suspect in the case and many questions remain unanswered. But officials believe Chasen's attacker fired shots into her passenger-side window from another vehicle and not from the street or a sidewalk.

"Indications are [the shots] could have come from another car, higher up, maybe an SUV," he said.

Police searched Chasen's Los Angeles condo and her West Hollywood office but had little immediate insight into who might have wanted to harm her.

Beverly Hills police Lt. Tony Lee said nothing had been ruled out, including a carjacking, a random attack or even a targeted hit.

Chasen, 64, was shot multiple times in the chest as she drove through Beverly Hills around 12:30 a.m. Tuesday.

Neighbors reported hearing gunfire and found Chasen's car crashed into a light pole on Whittier Drive, a street of multimillion-dollar homes just south of Sunset Boulevard, and a well-used shortcut to get to her home on the Westside of Los Angeles.

On Wednesday, at least one bus company that takes tourists past famous Hollywood sights was stopping to let customers gawk at the scene of the killing.

Her friends and colleagues wondered how the life of a woman who had spent her career rushing from red carpet to red carpet to charm the connected for her star clientele could have ended in such a violent way.

They said it was mind-boggling that anyone would want to see her dead.

"I mean, a publicist doesn't make that type of enemies," said Chasen's longtime friend, Oscar-nominated singer-songwriter Carol Connors, who co-wrote the theme to the film "Rocky."

Even in the sometimes cutthroat world of fighting for celebrity clients, Chasen stood out for her kindness and willingness to share credit, New York-based publicist Kathie Berlin said.

Berlin recalled a time years ago when the two were promoting the film "Thelma & Louise" and Chasen made sure Berlin shared credit for landing the film's stars, Geena Davis and Susan Sarandon, on the cover of Time magazine.

"We both worked on it, but truth is she made the call that got the cover," Berlin said.

Unless Chasen was leading some sort of secret life no one knew about, several people said, she'd be the last person they would suspect would be targeted.

She had little time for a secret life, they said, balancing her work with dining out at the trendiest restaurants just about every night and day of the week. She would always be in the company of friends and clients, who were often both.

Though by no means a household name, Chasen was a celebrity in her own right to those who work to promote Hollywood movies and their stars. The murder of one of their own has united the competitive community of behind-the-scenes Hollywood publicists, and prompted them to contribute big bucks for reward money to find the killer.
