Nick Stahl, best known for his role as John Connor in Terminator 3: Rise of the Machines, is MIA. According to a police report filed by his wife Rose, nobody has seen hide nor hair of the 32-year-old actor since early May. Although Stahl has a noteworthy career with more than 30 films under his belt, along with the hit HBO show Carnivale, he has a documented history of substance abuse. This could likely have something to do with his disappearance. This past February, Stahl's wife attempted to get court-ordered drug tests and supervised visits implemented to protect the couple's two-year-old daughter. She was also digging for child support because she isn't gainfully employed. According to Rose, her significant other made a whopping $500,000 last year. That kind of green can go a long way on Skid Row, which is where Stahl's supposedly been hanging out. Insiders tell TMZ that those close to the troubled actor believe he may have gotten in over his head. Stahl's wife is worried that drugs could be why he's missing. So far, Stahl's rep is remaining tight-lipped. Stahl isn't the only John Connor star to battle his drug demons. Terminator 2: Judgment Day star Edward Furlong also has a lonnnnnnnnng history of drug and legal problems. In addition to suffering from a heroin overdose, he's been arrested for driving under the influence. He has admitted to being addicted to cocaine and heroin. Furlong has also done his fair share of time in rehab.
