Police said the woman took her son to an emergency room where he had a core temperature of 109.8 degrees and was pronounced dead with rigor mortis already present.
The woman said her baby must have gotten too hot while they were running errands.
Police said there weren’t get any emergency calls about the boy the incident before the ER contacted police.
Santaquin is 54 miles south of Salt Lake City.
