HARWINTON, Conn. (AP) Connecticut State Police say a woman whose infant son was found dead in a bag in a reservoir is cooperating with authorities in the investigation.

State police said Thursday that the mother had come forward and spoken to detectives, and the child had been identified as a 1- to 2-week-old boy. Troopers said they were withholding the woman's name, and no charges have been filed.

Authorities said the woman received medical care at a hospital, but did not elaborate. Police also said she is a Connecticut resident.

The baby's remains were found Tuesday morning in a bag in a reservoir in Harwinton maintained by the Bristol Water Department. Water department employees discovered the body.

The medical examiner's office is trying to determine the cause of the infant's death.
