A partially decomposed body found Thursday in a wooded area off Governor Bridge Road near Bowie was positively identified yesterday as that of 28-year-old Jacqueline Rose Roberson, a first-grade teacher at Ardmore Elementary School, according to police.

The state medical examiner's office in Baltimore used dental records to determine the woman's identity, said Prince George's County police spokesman Robert Law. The cause of her death has been preliminarily ruled as stab wounds in the torso, pending a full autopsy report, which is expected in the next few days, Law said.

Police had no suspects yesterday, Law said.

The mystery surrounding Roberson's death began after she called her mother on Monday morning to say she was going to Allen's Pond to wax her car, police said.

On Tuesday, the car was found, half-waxed, on a shoulder of Governor Bridge Road near Bowie, five miles from the pond. The keys were on the front seat and there were no signs of struggle inside the car, Law said.

"The pond is a fishing spot so it's not unusual to find a car parked on the shoulder of the road," said Cpl. Bruce Gentile, a police spokesman.

She was reported missing Wednesday evening by relatives and her fully clothed body was found by police under a pile of leaves and twigs on Thursday afternoon, Gentile said.

"We are examining the possibility that she may have been killed there," he said.

Gentile said it had not been determined whether Roberson was sexually assaulted.

Roberson, a newlywed who lived in Bowie, recently began volunteer work for Bowie City Hall's Youth Services, a counseling and crisis intervention service.
