MANASSAS, Va. (AP) — The man accused by prosecutors as the East Coast Rapist confessed to police that he raped two teenage trick-or-treaters in Virginia in 2009, according to court testimony.

Authorities believe 40-year-old Aaron Thomas is responsible for rapes and other attacks on 17 women from Virginia to Connecticut over the span of a decade.

Thomas was in court Thursday in Manassas for a preliminary hearing. The three girls he allegedly abducted — two of whom were raped — testified in graphic detail about what occurred.

A police sergeant also testified that Thomas confessed to the Halloween rapes after he his arrest, but only after complaining that a police sketch failed to depict him properly.

The judge found Thomas competent to stand trial after a court-ordered evaluation concluded that he was faking insanity.
