A 13-YEAR-OLD Radnor girl who went missing on Monday was found safe late Tuesday night at a bus station in Washington, D.C., with a 20-year-old man who police say the girl met via social media.

Savanna Marie MacMullett was reported missing Tuesday. She had been last seen by her parents at 4 p.m. Monday, when she left their home after telling them that she was attending an after-school activity, said Radnor Lt. Chris Flanagan.

The girl, Flanagan said, was found in Washington with Ashley Ryan Hareford, 20, with whom police and her parents she might be. Flanagan said that an anonymous tip led authorities to the bus station, where MacMullett and Hareford were found.

Hareford was arrested there without incident and was facing a charge of corruption of minors.

MacMullett was being evaluated for "any medical or mental issues," Flanagan said. Radnor detectives were headed to Washington to interview Hareford and to bring the girl home.

On his Facebook page, Hareford, who lists himself as "married" and as a student of "The Juggalo University of Murder," dedicated several of his posts on Monday to MacMullett. One post reads: "I have 3 sides: 1.) The quiet, sweet side. 2. The fun and crazy side. 3. The side you never want to see."

On Sunday, police stopped Hareford near the girl's house for being suspicious, but released him. Officers later spoke with MacMullett's father, who was able to determine that his daughter knew Hareford.

Hareford has used social media to try to meet girls before. On DateHookup.com, Hareford said he's a guy looking for a "bi emo girl or sexy straight country girl."According to his social-media pages, Hareford is into drugs, raves and the Insane Clown Posse, a band whose fans refer to themselves as "Juggalos."
