Police have identified the man found dead in the campground at the Pemberton Music Festival as Nick Phongsavath, 21, of Regina, Sask.

Just after 6 p.m. PT, festival-goers found Phongsavath unresponsive inside his tent, which had been set up near a row of portable toilets at the north edge of one of the festival camping areas.

Local RCMP felt the circumstances surrounding Phongsavath's death were suspicious, and called in the Lower Mainland's Integrated Homicide Investigation Team. 

Investigators said Saturday that they had not confirmed the cause of the man's death, or whether foul play was involved.

“IHIT is working closely with the Sea-to-Sky detachment and have been interviewing witnesses and speaking with event attendees throughout the night," said IHIT's Sgt. Jennifer Pound. "At this point, there is nothing to confirm or definitively rule out foul play."

Investigators say an autopsy will have to be done to determine the cause of death.

IHIT initially withheld the deceased's identity as investigators were having trouble locating his next-of-kin. But as news of a suspicious death began to spread panic in the wider community, investigators issued a request through Twitter, asking festival-goers to get in touch with their families to let them know they are OK.

“It is estimated that there are close to 20,000 participants attending this music festival, creating a very dynamic environment for investigators," Pound said. "Whistler/Pemberton RCMP as well as HUKA event organizers have been extremely helpful in assisting IHIT with this investigation.”

Police are asking anyone with any information about Phongsavath's death to call IHIT at 1-877-551-4448. 

Anyone with questions about the festival itself are being asked to call HUKA's information line at 1-646-918-5130.

Campground area cordoned-off

Some of those camping at the festival say the campground has become an eerie place, with police tape surrounding a large space around the row of portable toilets and the tents where Phonsavath's body was found.

Reut Amit, who was camping across from the apparent crime scene, told CBC News a group of festival-goers discovered the man's body, and tried to keep others away until police arrived.

"Our tent is facing the port-a-potties, so we were sitting at our campsite and people were still using the washroom," she said. "It looked like a group of people were sort of blocking off this one port-a-potty and telling people not to go in."

"When police arrived, they cordoned off a small area at first. ... And then, eventually, they cordoned off a much larger area and then the entire set of washrooms couldn't be used."

Police later brought in a mobile command centre, and festival security told some of the campers that the area, which is between the Alberta and Saskatchewan camping areas, would remain cordoned-off all weekend.

Festival organizers said 55 campers were kept from accessing their belongings inside the taped-off area.

In a statement released Saturday, HUKA Entertainment said food, water, shelter and clothing were being provided to those people, who should be able to return to their campsites Saturday night.

Show will go on

HUKA Entertainment also expressed sadness about the death, and tried to reassure festival-goers that the campground was a safe place and that the show would go on.

'Inside the festival area we have arrested seven people since Wednesday. These arrests have been related to intoxication in public and causing a disturbance.'- Whistler RCMP Sgt. Rob Knapton

This year's Pemberton Music Festival features nearly 100 acts and predicted an attendance of 25,000 people.

The organizers from New Orleans, HUKA Entertainment, said they spent millions on improvements after a previous incarnation by another promoter in 2008 was marred by traffic jams, irritating dust and filthy portable toilets.

Whistler RCMP Sgt. Rob Knapton said traffic to and from the festival has yet not created any significant concern this year.

Knapton also said officers on the festival grounds have not encountered many incidents requiring police intervention.

"Inside the festival area we have arrested seven people since Wednesday," he said. "These arrests have been related to intoxication in public and causing a disturbance."
