( CNN) Three Mississippi teenagers are accused of killing a 6-year-old boy after stealing the car he was left in.

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 vehicle, 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 motorist of the Camry knew “their childrens” was in the car.
