MOORHEAD — The father of a 5-month-old girl who died after being left in a hot minivan forgot about the infant while unloading five other young children out of the vehicle, Moorhead police said.

Police said Christiana Natany Sandstrom died after she was left in her car seat in the van for about four hours Tuesday afternoon, when temperatures were reported to be about 80 degrees.

The girl’s father, Andrew Sandstrom, called 911 when he realized what had happened.

“The father was caring for his children. There were a total of six under the age of 7 he was responsible for,” Moorhead Police Lt. Tory Jacobson said Wednesday. “Ultimately he forgot and left his youngest child in the car for an extended a period of time.”
