The state is pulling Tot Town Learning Center's license after police cited its owner and two staff members for leaving a 4-year-old boy in a car.
It happened during a movie outing with a number of day care kids.
The report said it's unclear whether the provider and staff were aware the toddler had been left in the van.
But investigators concluded the "severity of the incident" requires revocation.
Documents quote day care staff who said when they returned from the movie, the child in the van was red in the face, and his clothes were wet from sweat.
The investigation said the approximate temperature during the time the child was in the van ranged from 75 to 80 degrees outside.
It further said according to the National Highway Traffic Safety Administration, the inside temperature can rise almost 20 degrees within the first 10 minutes.
The report said it was likely the temperature inside the van was above 110 degrees by the time the other children and staff returned to the van.
The report also said the daycare failed to get appropriate permission and documentation when administering medication.
The day care's owner and two other staff members were cited with misdemeanor child endangerment.
Tot Town's owner Melanie Hoke said she plans to fight the revocation.
She referred questions to her attorney, but he is out of town, and was not available for comment.
