Ashley Brown

Ashley Brown had been missing since April 24. Harris County Sheriff's investigators have always suspected that she ran off to meet a 33-year-old man she met online.

The 15-year-old continued to use her MySpace as recently as July 8. That allowed investigators to track her down via the Internet Protocol address that was registered to a computer network in Lawrence, Kansas, said Harris County Sheriff's investigators.

But it wasn't until Tuesday that police found Brown, who may have also been using the alias Arianna Maria Sanchez.

The unidentified man who Brown was with is expected to be charged with aggravated sexual assault of a child.
