BALTIMORE -- Baltimore County police said an Internet date ended in homicide, and they have a suspect in custody.

The body of Josie Phyllis Brown was found off an Interstate 95 exit ramp in Arbutus Tuesday night, and by the next day, her alleged date remained in police custody.

WBAL-TV 11 News reporter Tara Mergener reported Brown disappeared last December. Brown, of Baltimore's Hampden neighborhood, was reported missing from Baltimore City.

Police said John Christopher Gaumer, 22, told them that he killed the 27-year-old victim while he and Brown were on a date on Dec. 28, 2005.

"They got into an argument. They pulled over on the side of the road, on the ramp, and the argument became physical," Baltimore County police spokesman Bill Toohey said.

According to police, Gaumer admitted to leaving Brown near the highway ramp before he returned and allegedly beat her with a blunt object and threw her down an embankment.

Police said Gaumer led officers to Brown's body Tuesday night.

Authorities said Brown met Gaumer on the Internet Web site MySpace.com. While details of the relationship are unknown, police said Gaumer was a student at the University of Maryland-Baltimore County, where he lived on campus. Police said he has no criminal history.

"We had no problem with John, we had no reference to him on our file as to someone who made a complaint or someone had made a complaint about him," UMBC Police Chief John Cook said.

Campus police told 11 News Gaumer withdrew as a student from the university on Wednesday. He remains held in police custody without bail.
