Michael Shannon Thedford, 33, was booked into the Collin County Jail after the child was found unconscious inside the family’s van. A source close to the family told CBS11 that Thedford dropped off two children at daycare, but left the baby in the car.

“Forgetting a child? His child? It’s hard to believe because how can you forget a child in your own car? It’s your child,” said Fabiola Contreras, who lives across the street. “It’s really hot especially if you’re in a car, it’s way hotter.”

Contreras said she watched from her porch as paramedics and Collin County sheriff’s deputies arrived.

“They were asking the mother a few questions and she looked like she was crying. She was devastated. So was he, he would hug her and cry as well,” she said.

Capt. Jim Moody of the Collin County Sheriff’s Department said deputies were called about 1:30 p.m. Tuesday to the family home in Melissa, about 40 miles north of Dallas. They arrived to find the child removed from the car but unresponsive.

Witnesses said investigators appeared to make Thedford reenact what happened using a Mickey Mouse doll.

Contreras said Thedford was a very serious and quiet person.

Neighbors said Thedford is married and has two other young, children.

His bond is set at $20,000. Thedford’s jail record lists no attorney.

The National Weather Service reports the temperature at the nearby McKinney National Airport had risen to the low 90s but felt like the upper 90s by that time.
