PUYALLUP, Wash. – A Pierce County mother took the law into her own hands and beat up a sex offender who just moved into her neighborhood.

Residents at the River Road RV park said 24-year-old William Allen Baldwin has been living there for at least a year.

"He's a good guy," said his neighbor, Justin Williamson.

But then police came and handed out a flyer, notifying residents that Baldwin was a Level 3 sex offender who in his teenage years had molested numerous children.

Janet Hauff and Scott Pierce say their friend Tammy Lee Gibson saw the flyer and decided to hunt him down.

"She had no clue until she seen the papers and seen his face, and she flipped. She said, I know this guy, and she left," recalled Hauff.

Baldwin is 7-foot-3 and weighs 245 pounds, but police say that didn't stop Gibson from coming to his RV and beating him repeatedly with an aluminum baseball bat.

"I kept swinging and swinging and swinging," she later told police.

Gibson told friends that Baldwin had assaulted her child, but police say the accusation is unfounded.

Neighbors are now split. Some say he was trying to start a new life, others fear he was looking for a new crime to commit.

Tammy Gibson now faces charges of felony assault and harassment.

William Baldwin is now back in jail for failing to register as a sex offender.
