Chasen, 64, was gunned down last month as she drove home after a party celebrating the Cher-Christina Aguilera movie "Burlesque." Smith shot himself Wednesday as police attempted to serve a search warrant in the lobby of an apartment building.
Police officials told the Los Angeles Times they received several tips in the Chasen case, including one from the TV show "America's Most Wanted" that involved Smith.
Although some law enforcement sources categorized the man as a suspect to the newspaper, police publicly stated he was only a person of interest wanted for questioning.
"At this time, it is unknown if this individual was involved in the Chasen homicide," the Beverly Hills Police Department said in a statement issued to the Times.
