A police car is parked outside 75 Washington St. on Nov. 24 in Augusta, after 31-year-old Joseph Marceau was found dead there. Damik Davis, Zina Marie Fritze and Michael Sean McQuade were charged in connection with the killing, and police said Tuesday that a fourth suspect, Aubrey Armstrong, 26, of Far Rockaway, New York, is sought by authorities. Fritze died last month after she hung herself in her cell at the Kennebec County jail. Staff file photo by Joe Phelan
