Two men have pleaded guilty to manslaughter charges in relation to the deaths of William Ahenakew and Trez Sparvier-Scott, who were killed in a home on the Ahtahkakoop First Nation.

Kimmy Bear and Carl Anthony Albert had been charged with second-degree murder over the killings, which took place in November of 2011.

During proceedings Tuesday, court heard that Bear and Albert had broken into a house looking to steal drugs and money.

They were drunk and, during the break-in, they stabbed Ahenakew with a sword and struck Sparvier-Scott in the head with a dumb-bell weight.

They also set the house on fire. According to an autopsy report, Sparvier-Scott was still alive when the fire was started.

There was a 4-year-old girl in the home, hiding in an upstairs bedroom, at the time. She was rescued but did suffer some injuries from the fire.

Sabrina Sparvier lost a son, Sparvier-Scott, and a brother, Ahenakew, in the attack.

"No one should ever know that their kids are tortured and taken out and ripped out of their lives," the woman said after the court procedings. "It's not a safe world. It doesn't feel like a safe world anymore."

A third man who took part in the break-in, Dominic Ahenakew, tried to stop the attacks. He pleaded guilty to a robbery charge.

The judge on the case accepted the Crown's submissions on sentencing and imposed sentences of 15 years for Bear and Albert, and two years less a day for Ahenakew.
