The search for Bonney Lake teenager Lileana “Lily” Christopherson continues, but one suspect has been arrested.

According to the Bonney Lake Police Department, Christopher Fitzpatrick, 39, was arrested by U.S. Marshals on May 26 following an anonymous tip.

Fitzpatrick, a non-compliant registered sex offender who was convicted of third degree assault with sexual motivation in 2004, was taken into custody at a home in Lakewood at the cross section of Becker and Monterose Avenue SW.

He had warrants from the Washington Department of Corrections for violating his probation and failing to register as a sex offender, according to a U.S. Marshall Service press release.

The nature of the relationship between Fitzpatrick and Christopherson, 15, is unclear.

According to the BLPD, Christopherson took a bus to Federal Way on May 9 to meet up with Fitzpatrick.

Police believed they were traveling between Tacoma and Tumwater since Christopherson went missing. It is unknown to what extent Christopherson was willingly with Fitzpatrick.

At the time of the arrest, Christopherson was not with Fitzpatrick.

Christopherson is Caucasian female with long brown hair and hazel eyes. She is 5’2”, 120 pounds and has a small scar next to her left eye.

She was recently seen in Tacoma and may be accompanied by “a female with a dark complexion,” a BLPD release reads.

If you see Christopherson or have any information on her location, please call 9-1-1 and reference case number 1812901486.
