The inquest in Prince Albert, Sask. into the death of Kenton Carnegie, who died in a suspected wolf attack, is also hearing the possibility that a bear may have been involved.

Carnegie, a 21-year-old engineering student at the University of Waterloo in Ontario, was killed near Points North Landing in northern Saskatchewan in November, 2005. 

On the first day of the inquest Monday, a coroner's jury heard grisly details about the discovery of Carnegie's body.

Witnesses said there were wolves spotted in the area and they could hear wolves calling when they went to look for Carnegie, who went missing after going for a walk. One witness said it looked like wolves were nearby when Carnegie's remains were found.

John Morrall, the lawyer representing the coroner's office, has raised the possibility that a bear may have killed Carnegie.

An expert witness said there were bear tracks visible in one of the photographs taken in the area, although none of the witnesses said they saw a bear.

The focus of the inquest also shifted Tuesday to the role that an unregulated garbage dump may have played.

Environment department wildlife ecologist Tim Trottier told the inquest about a garbage dump near the camp, which is about 750 km northeast of Saskatoon.

Signs had been posted noting that wild animals feeding at the dump were losing their natural fear of humans, he said.

Trottier said wolves around the work camp were acting as if they had no fear, something that could make them dangerous to humans.

Meanwhile, Harold Johnson, the lawyer for the Carnegie family, said he doesn't think the unregulated garbage dump is an important part of the puzzle.

"It's a straw man argument," he said. "There's garbage dumps everywhere. Wolves don't kill everywhere ... there is a garbage dump. They are trying to draw a connection."

For Johnson, the focus of the coroner's inquest should be on proving that wolves killed Carnegie and that they are potentially dangerous predators that deserve our respect.

The inquest is expected to continue all week.
