In a statement released Tuesday, the Integrated Homicide Investigation Team said that the results of a July 21 autopsy, witness statements and evidence found at the scene all have "determined that foul play is not a contributing factor in [Phongsavath's] death."
The investigation has been transferred from IHIT to the Whistler/Pemberton RCMP.
Phongsavath, 21, was found unresponsive in his tent on the grounds of the music event shortly after 6 p.m. PT Friday.
He was a computer engineering student at the University of Regina and was set to graduate next year. He had been working as an intern for a Regina information technology company.
