WARREN, Pa.  — A federal grand jury in Erie has indicted a Maine man on charges that he accosted a couple at gunpoint in Pennsylvania’s Allegheny National Forest, tied up the man and raped the woman.

Thirty-five-year-old Mike Beaulieu, of Anson, was arrested last month in New Brunswick, Canada, where he remains imprisoned on a weapons charge for allegedly having a gun despite being a felony sex offender in Maine, where he once spent four years in prison.

Pennsylvania State Police had charged Beaulieu in the Aug. 3 attack at the Kinzua Point Information Center, but Tuesday’s indictment means those charges will likely be dropped.

Beaulieu faces up to life in prison if he’s convicted of aggravated sexual abuse, kidnapping, and weapons charges in the grand jury indictment.
