Friends and family of Nick Stahl are worried about the Terminator 3: Rise of the Machines star, who has gone missing less than one week after leaving rehab against doctors' advice, reports E! News.
"He's been missing for four days," says his wife, Rose Murphy Stahl. "But I don't want to comment any further."
It's the second disappearing act that Stahl has pulled this year. In May, the 32-year-old actor went missing and his wife filed a report with police. Five days later, Stahl sent an e-mail to friends assuring them that he was OK and apologizing for "worrying everyone." He wrote that he was checking himself into rehab.
