A Cleveland-area teen who police say ran away with a Missouri man only to be held against her will for weeks has been reunited with her family.

The 15-year-old returned home to suburban Cleveland Thursday night, two days after authorities found her in a home about 40 miles east of St. Louis.

Investigators said Friday that they were able to discover the missing teen's location by tracking Facebook messages.

Prosecutors say one message said: "I haven't hurt her, I don't plan on it, but she keeps crying."

Christopher Schroeder of Marthasville, Missouri, has been charged with transporting a minor to engage in criminal sexual activity. Court records show he told authorities he thought the girl was 18.

A message seeking comment was left with his public defender Friday.
