Police and the state medical examiner’s office are investigating after human remains were found Tuesday in the burned wreckage of a boarded-up commercial building. “The fire has been extinguished and upon inspecting the building, a male was located deceased inside,” Milford police spokeswoman Marilisa Anania said Tuesday. Police have established a perimeter around the scene at 51 Roses Mill Road. Milford police detectives and the city fire marshal are on the scene and investigating, Anania said. The address sits just off the Boston Post Road in eastern Milford adjacent to the lot that holds the Homegoods and Marshalls department stores. Photos of the building on Google Streetview show a three-story wood-framed structure with boarded up doors. State medical examiner James Gill said one decedent was reported to his office.
