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".

 A Seven Hills School sophomore made at least two 911 calls pleading for help Tuesday as he was being crushed to death in his van in a parking lot near the school. 
 
 Kyle Plush, 16, became increasingly desperate in the calls while the dispatcher struggled to pinpoint his location. 
 
 "Help, help, help," Plush said in a call he made at 3:16 p.m. "I'm in desperate need of help." 
 
 Plush said several times he was "at Seven Hills," though the operator apparently did not hear clearly or understand what he meant. "Where are you?" she said, over and over. "What is the address?" 
 
 In a second 911 call, Plush again begged for help. "I probably don't have much time left, so tell my mom that I love her if I die," he said. "I'm trapped inside my gold Honda Odyssey van. In the (inaudible) parking lot of Seven Hills Hillsdale. 
 
 "Send officers immediately. I'm almost dead." 
 
 A police radio call shows that two officers were assigned to investigate the call seven minutes after the first call was made. They arrived at the scene a few minutes later, but were unable to find the van. 
 
 Plush was found by a family member around 9 p.m. in a parking lot near the school in Madisonville, about six hours after his first call to 911. A preliminary autopsy report shows he died of asphyxia due to chest compression, meaning he was crushed to death. 
 
 The report does not say how it happened or how long it took for Plush to die. The Hamilton County Coroner's Office found no evidence of foul play, and Cincinnati Police say they are continuing to investigate. 
 
 "Our deepest sympathies are with the family and friends of Kyle," Coroner Lakshmi Sammarco wrote in a press release announcing the findings. 
 
 City Manager Harry Black said city officials, who run the 911 center, also are investigating the incident. "This matter is very disturbing," Black said. "If there are deficiencies on the part of the 911 center operations, my mandate is to fix whatever needs to be fixed." 
 
 Sometime after Plush's first call, the 911 dispatcher called back on his cell phone number, but it went to voicemail: "Hello, this is Kyle. I'm not available right now. I'll get back to you as soon as I can." 
 
 The operator then spoke to an unidentified deputy trying to locate Plush. The deputy speculated it might have been a prank call, but he continued to search the area. 
 
 "It was really hard to hear," the operator told the deputy. "It was really a strange call." 
 
 In Plush's second call to 911, a banging sound can be heard in the background. It's not clear from the calls if Plush can hear the operator or how close he may be to his phone. On several occasions, he calls for "Siri," the automated voice on iPhones. 
 
 Near the end of his second call, it sounds as if Plush is struggling to breathe. 
 
 About six hours later, around 9 p.m., more calls are made to 911 after officers and family members find Plush's body in the van. 
 
 "We are missing a kid and apparently he's been found in his car in the parking lot," said one caller, who works for the school. "I guess we need police and an ambulance there." 
 
 A night shift worker at the school also called 911, saying he was with Plush's father in the parking lot. He told the operator Plush was "turned over in the seat and stuck there." 
 
 "He's been there for awhile," he said. 
 
 There are not many details about exactly how Plush died or how he became trapped, but asphyxia is essentially death from lack of oxygen. Often, it happens when someone falls on the ground or a floor and a weight drops on his or her back. 
 
 About 800,000 Honda Odyssey vans were recalled in 2017 because of a problem with second-row seats accidentally tipping forward. Honda said last year it had received 46 reports of minor injuries related to the problem. 
 
 It's not known whether Plush's van was among those recalled. 
 
 In a letter sent to Seven Hills families Tuesday morning, a school spokesperson called the death "a tragic accident." 
 
 Plush joined Seven Hills in sixth grade, the letter states. 
 
 "He was a young man of keen intelligence, good humor, and great courage, and this whole community feels this loss very deeply."

 In this Tuesday night, April 10, 2018 photo, Cincinnati police investigate the scene where a boy was found dead in a minivan in the parking lot near the Seven Hills School campus in Cincinnati.

 CINCINNATI (AP) — Authorities in Cincinnati pledged Thursday to find out what went wrong in the death of a 16-year-old boy they say became trapped by a minivan bench seat in a school parking lot. His body was found about six hours after he first called 911. 
 
 Police Chief Eliot Isaac said something went "terribly wrong" in Kyle Plush's death. He said a dispatcher was put on administrative leave and that the actions of all personnel involved will be reviewed. Hamilton County Prosecutor Joe Deters said his office is trying to identify experts to help its own probe with the coroner's office. 
 
 The coroner ruled the teen died of asphyxia, from his chest being compressed. 
 
 A telephone message was left for his parents Thursday. 
 
 "This is a horrific tragedy," Isaac said. "We share in their heartbreak." 
 
 The teen first called 911 at about 3:15 p.m. Tuesday saying he was stuck inside a van in "desperate need of help." But he was unable to hear the dispatcher's questions, police said, and a callback to his cellphone after it disconnected went to voicemail. Responding police drove through the area looking for signs of anyone in distress, but saw nothing out of the ordinary in the school complex that has several parking areas. 
 
 A Hamilton County sheriff's deputy on traffic duty at the school also checked around, police said. 
 
 The teen called 911 again at around 3:35. Police said this time he provided a description of the vehicle as he desperately pleaded for help, but couldn't hear the dispatcher. Isaac said the information didn't get relayed to officers at the scene. 
 
 "This is not a joke," the teen said over 911." I'm almost dead." 
 
 He asked the dispatcher to "tell my mom I love her if I die." 
 
 Police were unable to locate him on any of several parking lots of the Seven Hills School complex. A Hamilton County sheriff's deputy on traffic duty as school let out also checked around, police said. 
 
 Police said a friend called Plush's parents that evening saying he hadn't shown up as planned for a tennis match. His mother used an app to locate his phone at Seven Hills. They called the county dispatch center, and police said family members then arrived at the unlocked vehicle with the unresponsive teen inside. Police and fire responders getting there just before 9 p.m. were unable to revive him. 
 
 The Seven Hills School sent out a message saying Plush had been a Seven Hills student since sixth grade. 
 
 "He was a young man of keen intelligence, good humor and great courage, and this whole community feels this loss very deeply," the school said. 
 
 "He was truly a spectacular person," classmate Preston Luniewski told WLWT-TV. "He just lit up the classroom." 
 
 Authorities indicated he was in the rear of the minivan when he became trapped by a seat. 
 
 A Honda spokesman identified the vehicle as a 2004 Honda Odyssey and said there had been no seat-related recalls for that model. 
 
 "Our hearts go out to the victim's family during this difficult time," spokesman Chris Martin said. "Honda does not have any specific information from which to definitively determine what occurred in this incident." 
 
 Isaac said police will also study possible police equipment malfunctions. 
 
 Mayor John Cranley urged prayers for the Plush family, "saying our hearts are heavy."

 Isaac said there is an internal investigation of the actions of all employees involved. 
 
 Following the city's news conference, the Hamilton County Sheriff's Office announced it would also be conducting an investigation to see if proper procedures were followed. 
 
 Deputy Doug Allen was directing traffic when school let out and assisted police in the search of Plush's van. He was unable to locate the van. 
 
 What we know 
 
 Kyle Plush died while trying to retrieve tennis equipment from the back of his minivan and was pinned by the rear bench seat, a law enforcement source with knowledge of the situation told the Enquirer. 
 
 The 2004 Odyssey has three rows of seating. Bucket seats are in the first two rows and a third row is a bench seat. 
 
 According to the source, Plush had climbed onto the back seat and was reaching over the seat into the back hatch to retrieve his tennis gear. The seat then flipped up and over toward the back hatch, pinning him upside down beneath the seat.

 Though the 16-year-old was able to call 911, apparently twice, police were not able to find him. He later died in his minivan Tuesday in a parking lot at Seven Hills School's Hillsdale campus. 
 
 Hamilton County Prosecutor Joe Deters announced Thursday afternoon his office would be launching an investigation into Plush's death following results of the Cincinnati Police Department's investigation. The investigation will be assisted by coroner Dr. Lakshmi Sammarco. 
 
 “This young man was trapped in the third-row bench seat, and it is called asphyxia due to chest compression," Deters said in a news release. "We are actively working to identify experts to assist us in this investigation.” 
 
 The Cincinnati Police Department is holding a press conference at 3 p.m. regarding Plush's death.

 Here's what we know 
 
 Kyle Plush was a sophomore at the school. A preliminary autopsy report states his death was due to asphyxia due to chest compression. The Hamilton County Coroner ruled the death accidental. 
 
 He called 911 just after 3:15 p.m. Tuesday and told the 911 operator he was trapped and "in desperate need of help." 
 
 A second call was placed, but it unclear when this call was made. During this call, the operator had trouble hearing Plush. The operator sent a code over the line that would display as text on devices used by the hearing impaired.

 After that code was sent, Plush said "I'm trapped inside my gold Honda Odyssey van. In the (inaudible) parking lot of Seven Hills Hillsdale... Send officers immediately. I'm almost dead." 
 
 Cincinnati Police Officers Edsel Osborn and Brian Brazile were sent to the area. They reported they were on the scene at 3:26 p.m. about 10 minutes after the first call was made. They did not find Plush. 
 
 A Hamilton County sheriff's deputy called in and said he was also searching for the caller. The deputy said he had an argument with a woman in a van earlier and wondered if that person was prank-calling 911. 
 
 The deputy said he saw only one van parked in the area. He told the operator, "I looked in the van. I didn't see anyone." He said he would keep looking around. 
 
 The dispatch report connected to those first calls contains GPS coordinates that point to the section of the parking lot where Plush was later found, that section has about 40 spots in it. It is unclear how police determined these coordinates. 
 
 Then there was a gap of over five hours.

 Plush was found by a family member around 9 p.m. in a parking lot near the school. He was no longer breathing. Several 911 calls were made by people at this time. 
 
 Officers Edsel Osborn and Brian Brazile responded again. One told the dispatcher, "We had a run there earlier today. We think somebody is playing pranks.” 
 
 The coroner's office reported Plush died in the van. 
 
 Visitation for Kyle will be at TP White Funeral home on Sunday, 2050 Beechmont Ave, Cincinnati, Ohio 45230. 
 
 Funeral services will be Monday, 9:30 a.m. at St. Rose Church, 2501 Riverside Drive, Cincinnati, Ohio, 45202.

 Unanswered questions 
 
 Why were police unable to locate Plush in the searches after his 911 calls? Plush said he was in a gold Honda Odyssey in the school parking lot. 
 
 Were 911 call takers unable to hear the information Plush was providing to them? An operator told the Hamilton County deputy it was "really hard to hear" the call, but it is unclear why information didn't make it to the officers on the scene. 
 
 How much of that information was passed along to police if it was heard? It is unknown if the make and model of the van or other details were passed along to officers on the scene, but city officials said Thursday that information from the second call didn't make it to officers. 
 
 Did the police or the deputy get out of their vehicles to search the area? 
 
 Was Plush reported missing? Calls and radio transmissions from around 9 p.m. reference a missing juvenile, but it is unclear if and when such a report was made. 
 
 Was the school contacted to help with the search? 
 
 Did the GPS coordinates on the dispatch report come from Plush's cell phone? If so, were the police officers conducting the search provided with that information? Those coordinates would have put police within a few dozen feet of his vehicle.

– A horrifying—and perplexing—case out of Cincinnati: A 16-year-old boy died Tuesday after two panicked calls to 911 in which he relayed that he was trapped and dying inside his minivan in the parking lot of his school. "I probably don't have much time left, so tell my mom I love her if I die," Kyle Jacob Plush said in the first call, which came just after 3pm. He "gasped, cried repeatedly for help, and struggled to communicate with the operator" during that call, WCPO reports, but ultimately the call cut off. Officers went to the scene but couldn't find the van and thought the call might have been a joke. But Kyle called 911 again and insisted it was not: "I am trapped inside a gold Honda Odyssey van in the parking lot of Seven Hills," he said. "Send officers immediately. I'm almost dead." Kyle's body wasn't found until nearly six hours later, after his family was told he had not shown up to a tennis match as planned. His mom used an app to determine his phone was in the school parking lot; family members arrived there around 9pm to find him, unresponsive, in his unlocked car, the AP reports. A source tells Cincinnati.com he had climbed onto the third-row bench seat to retrieve tennis equipment from the back of the van when the seat flipped toward the back hatch, trapping Kyle upside-down beneath it. "The young man was trapped in the third row bench seat, and it [was] positional asphyxiation" that killed him, Hamilton County Prosecutor Joseph Deters said while announcing a comprehensive investigation into Plush's death. Police Chief Eliot Isaac called it a "horrific tragedy" and said something went "terribly wrong"; he said information from Kyle's 911 calls did not get relayed to officers at the scene, and Cincinnati.com reports the dispatcher, who has been placed on administrative leave, seemed to struggle to understand him. Police are investigating whether human error or an equipment malfunction played a role.
