AUGUSTA (AP) — Maine State Police say a fourth person is being sought in what investigators described as the drug-related killing of a man in November in Augusta.

Police say 26-year-old Aubrey Armstrong from Far Rockaway, New York, is believed to have fled Maine after the killing of 31-year-old Joseph Marceau of Augusta. He was indicted last month.

Three others have been arrested.

Police arrested an Augusta couple, 27-year-old Zina Marie Fritz and her boyfriend, 45-year-old Michael Sean McQuade, last month. Fritz later killed herself in jail. Also charged was 25-year-old Damik Davis of Queens, New York.
