LIVINGSTON, Scotland, Aug. 23 (UPI) -- Investigators say that the Scottish schoolboy found dead was asphyxiated and may have known the person who killed him.
Police discovered Rory Blackhall's body on Sunday under an old tent. He was found less than a mile from Meldrum Primary School in Livingston where his mother had dropped him off three days earlier.
"Nothing I have heard suggests that there was a struggle," said Detective Inspector Tom Martin, suggesting that could mean the boy was with someone he knew, The Scotsman reported.
The 11-year-old boy was reportedly unhappy about the end of his parents' marriage and the recent death of his grandmother. Friends have also said that he was bullied in school.
Ian Stephenson, a forensic expert, said that the absence of signs of struggle or violence are unusual in a homicide.
"In some ways Rory was almost a walking victim," Stephenson said. "He was unhappy, his home life was difficult and he didn't want to go back to school. He may have been looking for a friend. The boy must have felt fairly safe with whoever he was with, as there is no sign of a struggle."
