WASHINGTON  — The accused East Coast Rapist says he doesn’t know why he couldn’t stop attacking women for nearly two decades.

“They were objects,” Aaron Thomas said in a series of telephone interviews from his jail cell in Virginia’s Prince William County. “Whoever came down the street, an object. … It’s awful. It’s scary. … I don’t know why I couldn’t just stop.”

Thomas said that he doesn’t think he is crazy, but that he knows something is wrong with him.

“I did so much, I can’t remember,” he said, adding that it all blends together.

Thomas, 40, is expected to plead guilty this month for the Halloween abduction of three women in 2009 in Prince William County and a Loudoun county rape in 2001. He faces the possibility of several life terms in prison.

Thomas is the son of a Washington police officer who later committed suicide. Family members described a troubled childhood that included a two-week stay at a psychiatric facility in Georgetown after setting a girl’s hair on fire. He later spent the first three years of high school in an Upper Marlboro treatment center.
