MADISONVILLE, OH (WLWT)  — Police say a father found his son, Kyle Plush, dead inside a van outside Seven Hills School.

The discovery came more than six hours after the man’s 16-year-old son called 911 to report he was trapped by a folding seat in his van.

Seven Hills School officials said Plush’s body was found inside his van Tuesday night, in a “parking lot adjacent to the Hillsdale campus.”

Plush’s death has been ruled accidental. An autopsy revealed he died of asphyxia due to chest compression, according to a coroner’s report.

No foul play is suspected, Hamilton County Coroner Lakshmi Sammarco said.

According to Lt. Steve Saunders with the Cincinnati Police Department, Hamilton County dispatchers received a call around 3 p.m. Tuesday from a person who said he was stuck inside his van.

A review of that 911 call by WLWT investigator Todd Dykes indicates the caller was Plush himself.

Tragically, it appears the Seven Hills sophomore could not hold his cellphone with his hands and was using voice commands to dial 911. That meant the police dispatcher who took the call could hear Plush but could not get him to pinpoint his location.

In the 911 call, Plush is heard saying, “I probably don’t have much time left, so tell my mom that I love her if I die.”

He told told dispatchers he was in a gold Honda Odyssey van.

“Send officers immediately. I’m almost dead,” he said.

Cincinnati police responded to the school’s campus along with a Hamilton County sheriff’s detail.

They canvassed parking lots of the school, Saunders said, but did not find anything. Authorities said they also tried calling the phone number linked to the 911 call, but no one answered.

Plush’s body was found by his father around 9 p.m. Tuesday, officials said.

The school called Plush’s death a “tragic accident.”

According to a release from the school, “Kyle joined the Seven Hills community in the sixth grade. He was a young man of keen intelligence, good humor, and great courage, and this whole community feels this loss very deeply.”

Plush’s classmate Preston Luniewski echoed that sentiment.

“He was truly a spectacular person,” Luniewski said. “He just lit up the classroom. He would always be in class, paying attention, really productive in that environment.”
