Prince George's police are searching for a 22-year-old honors student who disappeared from her damaged automobile on a rural Brandywine road early Saturday morning.

Stephanie Ann Roper, of 15321 Rolling Meadows Road in Croom, was last seen leaving the Clinton home of Lisa Thomas, her childhood friend and roommate at Frostburg State College, about 3:15 a.m. Saturday. The roommates were home for the weekend and had just returned from a night out in Georgetown.

Although she often spent nights at her friend's home, "for some reason my daughter decided that it would be better to come home," said her mother, Roberta Roper. "She didn't get much further than a mile."

Her daughter's car was found on a shoulder of Floral Park Road with three flat tires. The underside of the car was damaged, the rear axle broken and the doors locked. According to police, the car apparently ran off the road while going east and was moved to the opposite side of the road and parked.

A search of the woods surrounding the car was made by police dogs and by helicopter, police spokesman Robert Law said.

The Roper family is offering a $10,000 reward for information leading to the safe return of their daughter. Prince George's police are asking informants to call 868-7340.
