The baby was found just after 12:30 p.m. wrapped in blankets and sitting in a car seat at a house on Entrybrook Drive, Springfield police said on Monday. Authorities took it to Baystate Medical Center for evaluation.
It's unclear how old it was.
The Massachusetts Baby Safe Haven statute allows a mother to legally surrender a child under seven days old to a hospital, police, or fire station without facing prosecution.
Investigators said they are worried about the mother's health and hope to find her to make sure she is OK.
Springfield detectives asked anyone who lives on Entrybrook Drive or near there to check their security cameras for anything suspicious last week, especially on Friday night and Saturday morning. You can contact investigators by calling 413-787-6355 or contacting them through Facebook.
