Child stars who grow up and acquire drug problems are a dime a dozen in Hollywood, and it seems the stigma may have claimed its latest victim: Nick Stahl. The "Terminator 3" actor, who got his big break opposite Mel Gibson in 1993's "The Man Without a Face" when he was just 13, was reported missing by his estranged wife Rose on Monday, five days after she last saw him. A source tells TMZ that Stahl, who has a 2-year-old daughter, had lately been frequenting the drug-infested Skid Row area of downtown Los Angeles and that "he may have gotten himself involved in some bad stuff." As of Wednesday, a spokesperson with the LAPD announced that Stahl, 32, is still missing. This is just the latest in a string of concerning stories about Stahl, who until recently had a fairly clean record, at least publicly. In March, he was charged with "defrauding a taxi operator" after he stiffed a cabbie on an early morning $84 ride to Hollywood, for which he was arrested and spent one day in jail. Before that in February, Stahl's estranged wife asked a judge to limit his visitation with their daughter, Marlo, to eight monitored hours a week — and only after he could prove he hadn't done any drugs in the past 24 hours. In court papers, Rose revealed that she had moved out of the family home in January. Stahl, who also starred in the HBO series "Carnivale," "Sin City," and "In the Bedroom" with Sissy Spacek, is set to soon begin filming "The Unknown Son" with Val Kilmer, Gina Gershon, and Eric Roberts.read more
