Blacksburg, Va. – Virginia Tech gunman Seung-Hui Cho left behind few clues for medical examiners.
Dr. William Massello, the assistant state medical examiner based in Roanoke, said Sunday that Cho died from a self-inflicted gunshot wound to his temple after firing enough shots to wound his 32 victims more than 100 times.
But there was nothing unusual about Cho’s autopsy, he said, and nothing that would have hinted at any psychological problems that might have led him to commit the worst shooting massacre in modern U.S. history.
Pathologists sent blood samples for toxicology testing to determine if Cho was on drugs at the time of his rampage, but Massello said it could take up to two weeks to get results.
Police are still searching for a motive. Cho, a 23-year-old English major, left behind a package of videos and letters but did not say how he chose his victims.
Authorities had to return to the victims’ dorm rooms and homes to collect fingerprints so they could make identifications, according to an official close to the investigation who spoke on condition of anonymity.
Several of the victims had gunshot wounds to the head, the official said.
Many of the victims’ bodies left the medical examiner’s office Thursday, the official said, adding that several airlines offered to transport the remains back to families for free.
The official was not sure if Cho’s body was among those that had been released.
Also Sunday, state police said investigators have still been unable to definitively tie Cho to the dormitory where the first two victims were found. One of Cho’s guns was linked to the first shooting, but authorities have no other evidence that ties him to that crime scene.
Police searched the dorm again for fingerprints and other evidence Saturday as a final sweep before students returned today, and were reviewing the information, investigators said.
