The family of a young aboriginal man found frozen to death outside Saskatoon in 1990 has sued the city's police force and individual officers.

The suit by Neil Stonechild's family names former constables Larry Hartwig and Brad Senger, as well as the police chief at the time and several other officers.

The statement of claim alleges police engaged in "misinformation, obfuscation, deception and false assurances" when Stonechild's mother Stella Bignell asked about her son's death.

"They owe me and my family something for what happened. They should have done this a long time ago," she said.

The Saskatoon police fired the two former constables in November 2004 after a provincial inquiry implicated them in Stonechild's disappearance.

But the men denied even seeing Stonechild the night he disappeared, and they're trying to have their dismissal reversed.

Stonechild's frozen body was found on the outskirts of the city in November 1990, days after he was allegedly seen in police custody.

The family is asking for damages, including out-of-pocket expenses and funeral costs.
