WATERVILLE, Maine (AP) — Police say a 12-week-old infant has died at a homeless shelter in Waterville, Maine.

The cause of the baby’s death Wednesday at the Mid-Maine Homeless Shelter was unknown. State and Waterville police are investigating.

Deputy Police Chief Charles Rumsey tells the Morning Sentinel police were called to the shelter for an infant not breathing.

Shelter Executive Director Betty Palmer says efforts were taken to revive the infant.

She said she could not discuss whether the baby has a family living at the shelter, but she did say the shelter does not take children or infants without an accompanying adult.
