OMAHA, Nebraska — The driver of a van for a childcare center is facing criminal charges after police say he forgot about a 1-year-old child in the vehicle, who died after spending five hours in the van with temperatures in the upper 90s.

Ra’Miyah Worthington was pronounced dead Monday at Nebraska Medical Center, the Omaha World-Herald reports. Court documents say her body temperature was 109 degrees, the Associated Press reports.

The van’s driver, Ryan Williams, 62, has been charged with child negligence resulting in death. If convicted, he could be sentenced to a maximum of four years in prison.

Williams was driving the van for Kidz of the Future Childcare, KETV Channel 7 reports.

The World-Herald reports Williams told police he had nine children in the van. He said he became distracted when one of the children did not want to get out of the van. He said he failed to check the van again after managing to get the child out of the vehicle.

Ra’Miyah was found by Williams at about 3 p.m., when the temperature was 96 degrees and the heat index was 110 degrees, the World-Herald reports. Williams tells police he grabbed the child and ran inside the daycare center to call 911.

“He was responsible for getting those kids inside,” said Douglas County Chief Deputy Attorney Brenda Beadle. “That little girl was in that van between five and six hours with the temperature outside reaching nearly 100.”
