It would have been nearly impossible

for Myles Hill to get out of the van in which he died even if he tried because the locks were so jammed or old, they required a lot of force to open, a video shows.

Three-year-old Myles Hill had little chance of being able to unlock the doors of the day care van where he died even if he’d tried to escape, an Orlando Police detective found.

A detective’s experiment to unlock the doors of the van was made public Friday. The video is marked as evidence in the manslaughter case against the van’s driver, Deborah St. Charles.

“Essentially with all the doors locked, if Myles, in the condition that he was exposed to, was not able to override the locks manually by lifting up, he was essentially locked inside and unable to exit,” the detective said.

Myles was found dead in the back seat of the van Aug. 7, his socked feet hanging over the edge, as shown in photos also made public Friday.

Myles was left in the van for 12 hours in the parking lot of Little Miracles Academy on Plymouth Avenue near West Gore Street.

Investigators say St. Charles picked up Myles and other children in the morning, but failed to do the required head count and vehicle check when they were let out. She told detectives she locked the van when she left.

Temperatures that day reached the low 90s, with a heat index in the triple digits.

The detective’s face winces in the video as he uses his thumb to push the lock. “Ouch,” he said. Parts of the van’s doors were rusted and in poor condition, the detective said. One handle was completely gone.

Opening the sliding doors to the backseats required force, even when unlocked, the detective said. As he demonstrated, the door made a loud, creaking sound.

St. Charles, who remains in the Orange County Jail, told detectives she handed mops and brooms from the trunk of the van to kids she’d picked up to help her carry everything inside the day care.

She didn’t remember seeing Myles get out, and she didn’t remember handing him a mop or broom, according to her police statement, which was also released Friday.

St. Charles said she assumed he’d gone inside with the other kids. She said she went inside the day care on Colonial Drive for a few minutes before returning to the day care’s other location in the same van.

She told detectives she did not hear or see Myles as she drove the roughly two miles back to the Plymouth Avenue location, according to the statement.

The Department of Children and Families closed the day care after the boy’s death.

Owner Audrey Thornton is appealing to re-open it.

Myles’ family filed a lawsuit against St. Charles and Thornton, calling both negligent.
