 CLOSE The Hamilton County coroner said Wednesday she found no signs of broken bones on Otto Warmbier’s body, nor did she find that his teeth had been disfigured while he was imprisoned in North Korea as his parents claimed this week. Saying his son had been tortured, Fred Warmbier told Fox News in an interview on Tuesday, “As we looked at him and tried to comfort him, it looked like someone had taken a pair of pliers and rearranged his bottom teeth.”

 Warmbier died June 19, six days after North Korea released him. While Warmbier's family declined an autopsy, Sammarco said her office used extensive medical scanning and imaging for a "virtual autopsy" and that nothing more would have been gained by doing an autopsy so long after his brain damage occurred. She said she was surprised by the Warmbiers’ statements on TV, so on Tuesday, she asked Cincinnati forensic dentist Dr. Frank Wright to review the pathology reports. If we don’t have the science, we don’t conjecture.” 
 
 Sammarco, a neuroradiologist, was elected coroner as a Democrat in 2012 and re-elected last year. Otto Warmbier’s death on June 19 was due to an unknown injury that occurred more than a year before his death, Hamilton County Coroner Dr. Lakshmi Sammarco said at a news conference. North Korea had blamed botulism and the ingestion of a sleeping pill for Otto Warmbier’s problems and dismissed torture claims. Sammarco said Warmbier's body, including his skin, was in surprisingly good condition for someone who had reportedly been bedridden for more than a year, indicating he received regular care. Sammarco agreed with University of Cincinnati Health system doctors who treated Warmbier and said they found no evidence of botulism or evidence of fractures or healing fractures that might point to beatings. … I’m sure he had to have round-the-clock care to be able to maintain the skin in the condition it was in.” 
 
 Warmbier, a student at the University of Virginia and an experienced traveler, went to North Korea in December 2015 on a tour. North Korea has denied mistreating Warmbier, sentenced to 15 years of hard labor in March 2016 for allegedly stealing a propaganda poster two months earlier.
– The death of Otto Warmbier is a mystery and it will probably stay that way unless somebody from North Korea comes forward with information, Hamilton County Coroner Lakshmi Sammarco says. At a press conference in Cincinnati Wednesday, the coroner said the American student's death was caused by complications from brain-damaging oxygen deprivation around six months into his imprisonment in North Korea, but the cause of the initial "insult" could not be determined, reports Reuters. "We don't know what happened to him, and that's the bottom line," she said. Warmbier's family declined an autopsy, but Sammarco said a CT scan served as a "virtual autopsy." Sammarco, whose report stated there were no signs of torture on Warmbier's body, said he had apparently been well cared for during the year or more he was bedridden, the AP reports. Sammarco said she decided to speak to the press after Warmbier's parents told national media he had been tortured and "destroyed," the Cincinnati Enquirer reports. She said a forensic dentist found no damage to the 22-year-old's teeth, which father Fred Warmbier said looked like they had been rearranged with pliers. "They're grieving parents. I can't really make comments on their perceptions," she said. "But we here in his office, we depend on science for our conclusions. If we don't have the science, we don’t conjecture."
