Police say evidence shows an ex-con acted alone in gunning down Hollywood publicist Ronni Chasen.

Beverly Hills Police Chief David Snowden tells The Associated Press that Harold Martin Smith, a 43-year-old career criminal, was the person who shot Chasen last November as she attempted to make a turn at an intersection.

He adds there was no conspiracy to kill her.

Snowden said late Wednesday the case will be wrapped up in the next couple of weeks.

Police had looked at the possibility that Chasen was targeted by a hit man, but a tip to the show "America's Most Wanted" led detectives to Smith.

Smith killed himself when police tried to question him.
