A Prince Albert, Sask., man who helped chase a man into a frozen lake, leading to his death by hypothermia, has pleaded guilty to criminal negligence causing death.

Danni Justin Knife was sentenced this week to 10 months time served and will serve a period of probation.

Knife was originally charged with second-degree murder in the death of Christian Bird of the Ahtahkakoop First Nation, but he pleaded guilty to the lesser charge.

Three years ago, Knife, 19 at the time, and three teenage boys got into a drunken fight with Bird, 27.

On that night in May 2011, Bird was chased into frozen Sandy Lake, which is about 90 kilometres northwest of Prince Albert. 

The assailants threatened to hurt him more if he came back to shore. Bird was later found clinging to a piece of ice. He died from hypothermia.

Under his sentence, Knife will have no more time behind bars but will have a number of conditions imposed as part of his probation.

Some of those include a curfew, no alcohol, community service, and a requirement to write letters of apology to the family.

The Crown prosecutor told CBC News the family of victim understands why it is criminal negligence and not 2nd-degree murder. They're glad it's over, but Bird's mother is still angry and unhappy, the prosecutor said.

In addition to Knife, who is an adult, three youths have also pleaded guilty to criminal negligence causing death and have been sentenced to closed and open custody.

The closed custody terms range from six to 10 months.
