news reports that U.S. Marshals arrested a registered sex offender in Washington state under suspicion of abducting a 15-year-old missing girl. Christopher Fitzpatrick, 39, allegedly failed to register as a sex offender and violated his probation. Because the investigation into the girl’s disappearance is ongoing, additional charges may follow.

Police believe Fitzpatrick may have been with a teenage girl who has been missing since May 9. She has still not been found, but Fitzpatrick was arrested in Lakewood.

The girl allegedly snuck out of her parents’ house to board a bus headed to Federal Way to meet up with Fitzpatrick. According to one police statement, the girl had been spotted in Tacoma within the last few days.

Investigators aren’t revealing how the missing girl met or knew Fitzpatrick. He is currently being held without bond.

Fitzpatrick was convicted of assault and felony harassment in 2003 after repeatedly raping his wife at the time.

No pleas have been entered in court and there is no attorney on record for Fitzpatrick.

The missing girl was last seen wearing a black cut-off shirt and tan Capri pants, is 5’2” and 120 lbs.
