Dawn Broecke, 42, was charged with involuntary manslaughter after her foster son was found inside a car at the McMullen Creek Shopping Center off Pineville Matthews Road.
She turned herself in to police on Wednesday.
According to officers, Broecke works at the shopping center and said she didn’t realize she left him in the car until she got off work.
Police said when Broecke found her son in the vehicle around 5 p.m. on Aug. 29, she frantically called 911 for help.
When officers got there, they said they tried to save the boy and rushed him to Atrium Pineville, but it was too late.
