CINCINNATI -- Hamilton County Prosecutor Joseph Deters is launching a comprehensive investigation to determine what exactly went wrong that led to the death of a 16-year-old Seven Hills student in the school parking lot Tuesday afternoon. 
 
 "The young man was trapped in the third row bench seat, and it is called positional asphyxiation," Deters said. "We are actively trying to identify experts to assist in us in this investigation." 
 
 Hamilton County Sheriff Jim Neil and Cincinnati Police Chief Eliot Isaac have also ordered investigations into the incident. Isaac said one 911 operator has been placed on administrative leave. 
 
 Just after 3 p.m. Tuesday, 16-year-old Kyle Jacob Plush called 911 panicking. Over the course of a three-minute call in which he gasped, cried repeatedly for help and struggled to communicate with the operator, he relayed that he was trapped inside his car in the parking lot of Seven Hills School. A source close to the investigation said Plush was going to get his tennis racket from the van when he became trapped. 
 
 "I probably don't have much time left, so tell my mom I love her if I die," he said. 
 
 The call ended; when officers checking out the scene attempted to call back, it went to voicemail.

 A deputy sent to the scene soon after called in to report that he couldn't find anyone trapped in a van. He questioned if the call had been a prank. 
 
 Plush was there. He called again. 
 
 "This is not a joke," he said. "I am trapped inside a gold Honda Odyssey van in the parking lot of Seven Hills. ... Send officers immediately. I'm almost dead."

 At several points in the second three-minute call, during which the operator does not respond and loud banging or heavy breathing can be heard, he attempts to call on the Siri automated iPhone assistant without success. 
 
 WCPO is not publishing Plush's 911 calls due to their graphic, disturbing nature and out of respect to his family. 
 
 Nick Francis, director of Experiential Learning at Seven Hills School, said in a 911 call a security guard contacted him and told him to call 911 because they found a kid in his car. Francis told the dispatcher he wasn’t at the school, but they had been “missing a kid.” 
 
 “I got a call from a security guy there because we were trying to find this kid, and he just all of a sudden called me, 'Nick we found him. Call 911, he's in his car,’” Francis told the dispatcher. 
 
 Around 9 p.m., according to police, a family member discovered him dead inside the van -- a death Hamilton County Coroner Lakshmi Sammarco would rule accidental "asphyxia caused by chest compression." 
 
 Something -- neither Sammarco nor Lt. Steve Saunders indicated what -- had pressed so hard against Plush's chest that he suffocated. 
 
 The information released by police Wednesday afternoon did not clarify the reason the first deputy to respond was not able to find Plush's van or where Plush had been inside of it. Plush's uncle, who declined to share his name or speak on camera, said Wednesday night the 911 system failed the "great kid" who had been his nephew. 
 
 Plush was a student at Seven Hills, spokeswoman Christine Hedges said Wednesday morning. The school has grief counselors on hand for any student who needs them. 
 
 City Councilwoman Amy Murray, whose child also attends Seven Hills, also promised a full investigation into the incident on Thursday on WLW. She called it a "sad, sad day." 
 
 Cincinnati Councilwoman Amy Murray calls it "heartbreaking". She is promising a full investigation into death of a Seven Hills student. Murray is the parent of a student at the school as well and calls this "a sad, sad day".

 City Council calls for outside investigation into Kyle Plush case 
 
 The father of a 16-year-old Ohio boy who died despite calling 911 while trapped in a minivan asked authorities Monday why responding officers didn't get out of their cruiser to search, and whether exact GPS coordinates existed for his son's location. 
 
 Appearing at a Cincinnati City Council meeting on the response to his son's death, Ron Plush promised to help improve the city 911 system but also said he would be asking difficult questions along the way. 
 
 Plush found the body of his son, Kyle, on April 10 inside the 2004 Honda Odyssey in a parking lot near his school nearly six hours after the first 911 call was made. 
 
 A coroner says he died of asphyxiation from his chest being compressed. 
 
 It is suspected that the foldaway rear seat flipped over as he reached for tennis gear in the back. 
 
 "Kyle will give us the strength and guidance to get the job done," Ron Plush said. 
 
 Mayor John Cranley told Plush he would receive written responses to every question and called the police report on the case incomplete. 
 
 Cranley opened Monday's meeting by saying the city failed in its response to the 911 call. 
 
 "In all cases we can do better, we should do better, we must do better," Cranley said. 
 
 Cincinnati police chief Eliot Isaac presented the results of an internal investigation before the City Council's law and safety committee, providing details of the 911 call and the police response. 
 
 Among the information released Monday: 
 
 The city's computer assisted-dispatching system experienced difficulties throughout the call. 
 
 Kyle's phone was in his pocket as he called, and he was using "Siri" caller technology to call 911. Kyle was not able to give back and forth answers to a dispatcher, and the phone disconnected his call. 
 
 The automated 911 response overrode Kyle's initial comments, which weren't heard by the dispatcher. 
 
 Officers initially believed they were searching for an elderly woman locked in her vehicle needing help. 
 
 Officers weren't given information from the initial call 911 that someone was banging and screaming for help. 
 
 Isaac said officers determined they could search a bigger area and see more by staying in their cruiser. 
 
 The boy's aunt, also attending Monday's meeting, noted that Kyle Plush's voicemail included his name, and was not a generic message. 
 
 If authorities knew the name "Kyle" and that the call was from someone near a school, they had enough to do a proper search minutes after the call was received, said Jodi Schwind. 
 
 Council members also questioned why officers didn't just search all the vans in the parking lot that day. 
 
 "Kyle did everything he should have done, everything a mom, a dad, would tell their child to do, he did," said councilwoman Amy Murray. "And he was failed horribly." 
 
 Some new details were revealed in the report. 
 
 Investigators said Kyle Plush’s cellphone was in his pocket. That’s why he couldn’t hear or be heard clearly by 911 dispatchers. 
 
 The report also verified that dispatchers had the coordinates given by Kyle Plush’s cellphone. The coordinates were not used to try to determine where he was. 
 
 “If you put in those coordinates, where does it come up and why didn’t you do that?” council member Amy Murray asked investigators. 
 
 Investigators acknowledged that the coordinates came back to a location very close to where Kyle was found. 
 
 A WLWT test showed the coordinates dropped a pin within a matter of a few feet of where Kyle Plush was eventually found dead. 
 
 City Council voted unanimously Monday to bring in an outside investigative entity. 
 
 The Hamilton County sheriff's office, which also dispatched a deputy that day, is also investigating, as is the county Prosecutor's Office. 
 
 Hamilton County prosecutor Joe Deters said his office won't do anything until the outside investigation is complete. 
 
 Council members scheduled a meeting May 29 for police to provide answer to questions raised Monday.
– Kyle Plush managed to call 911 twice from the third-row seat of the van in which he had become trapped on April 10, using Siri to place two calls from the phone in his pocket. The 16-year-old suffocated in the parking lot of Cincinnati's Seven Hills School, and on Monday the City Council's Law and Public Safety Committee was presented with the findings of an investigation into the teen's death and discussed them publicly. Police Chief Eliot Isaac, his investigators, and technical staff were the ones sharing the findings, reports WLWT. The most looming question, per the Cincinnati Enquirer: "whether 911 operators and police officers responded appropriately to Kyle's two calls for help." The report concluded 911 operations and police did act appropriately, but the report cites technical and personnel failings that produced the failed response. "We failed to get the outcome we wanted in this emergency response," said Mayor John Cranley. The investigation found that the two officers who responded to the 911 calls erred in turning off their body cameras 3 minutes into their 14-minute search, reports Fox 19. Isaac said the officers drove through lots looking for Kyle over the course of those 14 minutes; that included the lot where he was trapped. They at no point exited their vehicle, a decision they said was made in order to cover the most ground and because the lots were crowded due to school just ending.
