WREG reports that according to Millington Police, the child found the gun in a bag inside of an antique WWII vehicle that was on display at the Millington USA Stadium. The child and his mother were attending a UT-Martin vs University of Memphis Baseball game at the stadium.
"The juvenile believed it was a toy gun. He picked the gun up, pulled the trigger and accidentally shot his mother. It was an accident, pure and simple," said Millington Police Chief Mark Dunbar.
The mother was rushed to a Memphis hospital, listed in critical condition.
Dunbar also said, "Charges are possible. We will confer with the Attorney General's Office after we complete our investigation."
Police are hoping the investigation will answer why the weapon was left in the car, why it wasn't secured, and why it was allowed to get into the hands of a child.
