A serial rapist who attacked three trick-or-treaters on Halloween has been linked by DNA to 13 other sexual assaults around D.C. and up and down the Eastern Seaboard, authorities said.

Police said the rapes took place over a span of nearly 13 years and were spread out from Northern Virginia to Rhode Island. Authorities from four states and the FBI are now asking the public to provide information to bring the serial rapist to justice.
