Police will be charging a Rehoboth man with murder after human remains “consistent” with those of his pregnant girlfriend were discovered at his home Tuesday evening, according to Bristol County District Attorney Thomas Quinn III.

Gregory Groom, 22, was initially charged with aggravated assault and battery on a pregnant woman, domestic assault and battery and intimidation of a witness.

Investigators believe Groom attacked his girlfriend, 18-year-old Kylee Monteiro, on Aug. 6 at his residence on County Street.

Quinn said detectives found human remains on the property that are believed to belong to Monteiro, who was first reported missing by Groom earlier this month. He confirmed Monteiro was 11 weeks pregnant at the time of her disappearance.
