Mourners gathered for a candlelight vigil
Rescue workers have found the bodies of all eight snowmobile riders who were buried under two avalanches in western Canada's Rocky Mountains.
The incident, which happened on Sunday near Fernie, British Columbia, followed days of heavy snow in the region.
One avalanche buried a group of seven men - another four who went to help were buried by a second slip. Three men managed to pull themselves free.
The last of the bodies was found soon after the search resumed on Tuesday.
Early on Monday, rescue workers dropped explosives from a helicopter onto slopes around the avalanche area to shake loose snow free and make it safe for searchers.
Trained teams with dogs then began a search at the scene, police said.
The three men who pulled themselves from the snow tried to find their companions but had to give up because one was injured and they feared another slide, he said.
One of them went out with rescue teams on Tuesday to search for Mr Bjarnason.
Mr Roberts told a news conference that nobody, especially the survivors, was to blame for the accident.
"Don't blame yourself. It's an act that happens," he said.
Some 27 inches (68 cm) of snow have fallen in the region in recent days. Forecasters had warned that the danger of avalanches remained high - hampering the search effort.
