Alabama ? Authorities on Tuesday found the body of 5-year-old Geontae Glass, who’d been reported missing Monday by his 25-year-old mother.

Shalinda Glass had said he was asleep in the back of a car when it was stolen. She was charged with hindering prosecution, and her boyfriend Kevin Andre Towles was charged with capital murder. They were both being held in the Etowah County jail in Gadsden Tuesday night.

Authorities found the boy and the car in a closed garage at a house in rural Etowah County.

Sheriff James Hayes said Glass told police that her son, who was in kindergarten, died from a beating after he brought home a bad progress report from school Friday.

The mother had reported Monday morning that her car was stolen in the parking lot of a convenience store in Albertville. Witnesses reported seeing a man get out of a pickup truck and get into the vehicle, then driving away while someone else drove off in the pickup truck. Investigators believe the dead child was in the car when his mother went to the store with her 7-year-old daughter.
