Investigators believe that there were suspicious circumstances involved in the man's death, though it's not yet clear whether the death was a homicide or suicide, according to Chelsea police Chief Brian Kyes.
The man lived in the building, an affordable housing community on Clark Avenue and Cabot Street, according to police, who were waiting to speak to family before identifying the man.
