A Colorado teen who disappeared last month with a sex offender has been found safe, FOX News has learned.

A media tip led police to Amber Nicole Westbrook, 16, in Conifer, Colo., west of Denver, as well as Matthew Preston Caulk, a 40-year-old sex offender.

The U.S. Marshals Service and Lakewood police have been searching for the teen since Sept. 26, when she disappeared with Caulk.

Caulk is wanted in Yellowstone County, Mont., for failing to register as a sex offender, Deputy U.S. Marshal Robert Rodriguez said.

He was convicted of sexual misconduct with a child in Pierce County, Wash., in 2002.

Police have taken Caulk into custody. Westbrook is being reunited with her family.
