SPRINGDALE (KATV) - Two children are dead on opposite sides of the state. Both from being left in hot cars.

In Springdale, police say a two year old boy was left in the Wal-mart parking lot inside a dark car with the windows up and no air for more than two hours.

The boy was taken to the emergency room where he was pronounced dead.

Police say the child was under the supervision of his great grandparents at the time of his death. They allegedly told police they thought they had only been in the store for 45 minutes. But surveillance video shows the car was actually there for about two hours.

It's up to the prosecuting attorney if they will be charged with a crime.

Police say it was 102 degrees outside when the child died and that the temperature likely rose to 150 degrees inside the car.

KATV Channel 7 has also confirmed the death of a child in a hot car in Newport. Police are investigating the death but did not offer any additional information.
