Nick Stahl Missing Again After Leaving Rehab

'Terminator' star checked himself out of rehab a week ago and is now MIA.

For the second time this year, troubled "Terminator: Rise of the Machines" star Nick Stahl has gone missing
. The 32-year-old actor entered a rehabilitation facility in late May and was expected to spend 30 days inside.

But, according to E! Online friends and family are once again concerned for his safety after he checked out of the facility against doctors' advice a week ago and is reported missing. His estranged wife, Rose Murphy Stahl, said he's been MIA for four days, but refused to comment any further on his situation.

The site reported that Stahl went to stay with a friend after leaving rehab and was then seen around downtown Los Angeles before going back to a friend's house. He has not been seen since he left that house on Thursday.

An unnamed source told E!, "Now he's disappeared. We can't find him anywhere," they said of the so-far futile search efforts. "He has not made contact with anyone. We are all just desperately looking for him ... Everyone just wants him to come home. It's a terrible situation. We are searching, but we have no solid leads."

Stahl made his big-screen debut back in 1993 opposite Mel Gibson in "The Man Without a Face." Since then, he's appeared in several major studio films, including "The Thin Red Line," "Disturbing Behavior" and "Sin City." His most recent role is in the 2011 VOD-released "388 Arletta Avenue" opposite Devon Sawa.

As his big-screen career has stalled, those close to him fear Stahl has fallen into a spiral of addiction. This latest incident was not the first time that those close to Stahl have expressed concern over his well-being.

Rose, who married the actor in 2009, filed papers with the LA County Superior Court back in February asking a judge to limit her husband's access to their 2-year-old daughter, Marlo, due to his alleged drug and alcohol abuse. She also claimed that she and Stahl were no longer living together.
