William Hendrickson: 'Friday the 13th' fugitive is sex offender who terrorized 79 year old woman

WANTED BY DOC IN KING COUNTY -- It's Friday the 13th weekend, and while this guy isn't a maniac in a hockey mask like Jason Voorhees – he is a missing high-risk sex offender who terrorized a 79-year old woman. William Hendrickson is a level three sex offender -- the worst of the worst -- who worked at the apartments where she lived. He was drunk and harassing her one night, saying she was pretty and wanting a hug. After a while she said goodnight and headed to her apartment -- but minutes later -- Hendrickson ambushed her in the hallway. “He grabbed the victim and dragged her into the elevator,” says Department of Corrections Ofc. Emily Isaacs. “He began attacking her, trying to rip her clothes off. He was able to get her shirt ripped. He was probably going to do a lot more, however, the elevator door opened. He proceeded to drag her back out of the elevator onto a new floor, dragged her out by her hair. Fortunately another resident heard her screaming and came to her aid."

William Hendrickson is 44 years old, and goes by "Will", and the fake name "Vaughn Wilson". Along with his sex crime, he's been busted for burglary, drugs, lying to police -- and now he's wanted by the DOC for Failing to Register as a Sex Offender in King County.
