EASTON (CBS) — A 27-year-old mother has been criminally charged after her 17-month-old son was left alone in a shopping cart over the weekend. The boy was discovered in the Easton Target parking lot by a good Samaritan about an hour before someone who knows the child called 911 to report he was missing.

The mother was charged with abandonment/endangerment of a child and will appear in Taunton District Court at a later date. Easton Police did not identify the woman, beyond saying that she is a resident of Acton, Maine, in order to protect the boy’s identity.
