Emergency medical crews responded to a 9-1-1 call at a Midlothian day care Thursday afternoon on a report of an unresponsive infant.

Police and EMTs rushed the 4-month-old boy by ambulance to the emergency room of Baylor Medical Center at Waxahachie, where the infant was pronounced dead by Justice of the Peace Bill Woody.

“The call came in from a home day care in the 200 block of Hillcrest Drive in the subdivision south of Midlothian High School,” said Sgt. Kevin Johnson, spokesman for the Midlothian Police Department. “The owners of the daycare have told us they were licensed and, while we will check with the state to confirm this, at this point we don’t have any reason not to believe them.”

Johnson said the owner, who he did not identify, was being very cooperative.

“We have been told there were 12 kids at the childcare, mostly younger children,” Johnson said. “There were at least three adults at the day care.”

State law requires there be a 4-to-1 ratio for infants with the number of children higher per adult for older children.

The Texas Department of Family and Protective Services has oversight of day cares.

Johnson said officials with the state agency are being notified and would be part of the Midlothian Police Department’s investigation.

The infant’s body was sent to the Dallas County Medical Examiner for an autopsy, he said.

Johnson would not speculate on a cause of death or release details about how the child was found.

“We don’t have a lot of information at this moment as the investigation is under way,” Johnson said. “The call came in about 3 p.m. Thursday.”
