She drew a picture of him for police. Not surprisingly, his face is etched in her mind's eye forever.

He is her rapist.

Prince William County police say the woman was walking her bicycle along Mountain Road toward Route 15 about 8:30 a.m. on July 26 when a reddish sports car passed her.

When the car came back, the man who got out of the vehicle told her he was running out of gas and asked for directions. Then he hit her in the face, dragged her into a nearby wooded area and raped her, the woman said.

"I was traumatized by him hitting me," said the woman, a 26-year-old Manassas resident. "I was hurt. I was bleeding. He threatened to hit me again so I didn't want to antagonize him."

That rape, county police said, is one of 29 rapes reported in the first six months of this year, up from 25 last year. There were 48 reported rapes in 1989.

Prince William police spokeswoman Kim D. Chinn said the man suspected in the July 26 rape, who is not known by the victim, may be from a neighboring county. The attack occurred on Bull Run Mountain, which is frequented by residents from other areas, police said.

Investigators are looking for a man in his early to mid-twenties, with sandy brown or blond hair. The suspect has an overlapping front tooth and small hands. He is 5 feet 8 to 5 feet 10 inches tall and weighs about 150 pounds, police said.

The woman said he was wearing faded blue jeans and a white T-shirt when he attacked her.

The woman said "he talked country, with a southern accent." His medium-length hair was dirty and unkempt and his teeth were crooked, she said.
