KTLA-TV, Los Angeles, reported the development in the case Monday.
Chasen, 64, was gunned down Nov. 16 as she drove home after a party celebrating the Cher-Christina Aguilera movie "Burlesque." Smith shot himself Dec, 1 as police attempted to serve a search warrant in the lobby of an apartment building.
Law Enforcement officials said last week 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 Los Angeles Times, police publicly stated he was only a person of interest wanted for questioning.
