The DA issued this release Monday afternoon:

Chelsea Police detectives and State troopers assigned to the Suffolk DA's office are investigating the death of a 4-month old boy earlier today, Police Chief Brian Kyes and District Attorney Daniel F. Conley said.

A family member found the child unresponsive in their Washington Avenue apartment at about noon. He was transported to Whidden Memorial Hospital, where he was pronounced deceased. A preliminary examination of the body did not reveal immediate signs of violent trauma and the Office of the Chief Medical Examiner will conduct an autopsy to determine the cause and manner of his death. Detectives have likewise not developed evidence of foul play but their investigation remains active.

As with all death investigations, anyone with additional information is asked to share it with police. Chelsea Police detectives may be reached at 617-466-4805 and the Suffolk County State Police Detective Unit, which has jurisdiction over unattended deaths in Chelsea, may be reached at 617-727-8817.  

A neighbor told the Boston Herald she saw a frantic woman in the home’s foyer holding a child in her arms and screaming.

“She was crying, saying, ‘My baby’s not breathing! My baby’s not breathing!’” the neighbor told the paper.
