Authorities in Florida say a 4-year-old whose mother left him in a hot car in West Palm Beach has died.
The Palm Beach County Sheriff's Office says the 29-year-old mother may not have known the boy was in the car. She dropped off children at a relative's house before going to a nail salon Saturday.
It's not yet know how long the boy was left in the car.
Someone made a 911 call later in the day to report the boy was not breathing. He was taken to Palms West Hospital, where he was pronounced dead.
The victim's name is not yet known.
