The child, Kingston Frazier, was left alone in a Toyota Camry in a Kroger parking lot around 1:15 a.m. Thursday, authorities said.
The three suspects pulled into the parking lot in a separate car, the Hind's County Sheriff's Office said in a statement. One of them allegedly got into the Camry before both vehicles pulled away. It's not clear whether the driver of the Camry knew the child was in the car.
