Winthrop Police and State Police homicide detectives assigned to Suffolk County District Attorney Daniel F. Conley’s office are investigating an unattended death near a Winthrop Street residence this evening.

Winthrop Police responded to the area of 429 Winthrop St. at about 2:30 this afternoon for a report of a strong odor. On arrival, they observed what appeared to be human remains. Winthrop Police then notified the Suffolk County State Police Detective Unit, which investigates all unattended deaths in Chelsea, Revere, Winthrop, and parts of Boston.

Winthrop Police are providing support, assistance, and personnel to the investigation. The State Police Crime Scene Services Section is also assisting in the probe.

The remains appear to be those of an adult, but the decedent’s age, gender, ethnicity, and cause of death were not immediately apparent because of decomposition. Additional examination by the Office of the Chief Medical Examiner is expected to reveal some of those details after an autopsy, which will likely begin tomorrow.

Anyone with information on the case is asked to call Winthrop Police at 617-846-1212 or the Suffolk County State Police Detective Unit at 617-727-8817.
