A Maryland boy called 911 Friday to report that he and six other children had been left in a hot car with the windows rolled up and the motor not running, police said.

The Charles County Sheriff’s Office said in a press release that the children's ages ranged from 2 to 4 years old, and it was likely the eldest who called 911. The boy reportedly told authorities that the children were hot and didn’t know where they were.
