A Minnesota boy died and his twin brother was taken to the hospital after police found them suffering from extreme heat in a car. 

The 3-year-old twin boys went missing in Hibbing around 5:30 p.m. Tuesday. The boys were in the care of their father at the time they were reported missing, Hibbing Police Chief Steve Estey said. 

A citizen found the boys about an hour and a half later in the father’s truck near their home, and the person contacted police.

Police said they "broke out the window to gain access to the boys."
