Police are asking for the public's help locating a fourth suspect in connection with an Augusta homicide.

Public Safety Spokesman Steve McCausland says three people have already been charged in the death of 31-year-old Joseph Marceau, who was killed in November. State Police say Marceau's murder inside a Washington Street apartment was drug-related.

Currently being sought is 26-year-old Aubrey Armstrong of Far Rockaway, New York. Police have been looking for him ever since he was indicted by a Kennebec County Grand Jury last month. Armstrong is described as 5'8" tall, weighing about 155 pounds, and going by the street name 'Butta.' McCausland says, following the homicide, Armstrong is believed to have fled back to New York. State Police have received help from the U.S. Marshal's Service and New York law enforcement agencies, but have not yet located him. His last known permanent address is 2312 Oceancrest  Blvd, Far Rockaway, NY.

Already charged for Marceau's death are Damik Davis of New York, and Zina Fritze and Sean McQuade, both of Augusta. Fritze committed suicide in her jail cell two days after being charged for the death.

State Police say there's no indication that Armstrong has returned to Maine but, since he has not been apprehended, the decision was made to release his identity. Anyone with information about his whereabouts is urged to call State Police in Augusta at (207) 624-7076 or their local law enforcement agency.
