Not mafia but LA has some gang members that were also serial killers. Timothy McGhee of Toonerville was one. Walked up behind a high school student sketching a picture at the LA riverbed and shot him in the head, then shot a homeless person who witnessed it. He killed several people he suspected of talking to police. He also shot at Kurupt and the Dogg Pound when they were recording near Toonerville's hood, killing a bodyguard. Everyone thought it was DMX's crew but it turned out it was this sick fuck.
He found his way onto the tv show America's Most Wanted. Eventually apprehended in '03. Today he sits on death row at San Quentin.
"...the successful annihilation of organized crime's subculture in America would rock the 'legitimate' world's foundation, which would ultimately force fundamental social changes and redistributions of wealth and power in this country. Meyer Lansky's dream was to bond the two worlds together so that one could not survive without the other." - Dan E. Moldea
