Police responded to a home at about 2:15 a.m. where they found two men who had been stabbed.

Both were taken to hospital with life-threatening injuries. Lund later died, while the other man was upgraded to stable condition.

Investigators said a group of people were at a house party when a verbal altercation broke out. The argument escalated and a man assaulted the other two victims.

"Sounds like there was a party going on and whatever reason a verbal argument took place between the suspect and two victims and that sustpect did arm himself with a weapon," said Const. Eric Hofley with Winnipeg police.

The suspect then fled the scene.

A short time later police found and arrested Joseph Biggeorge, 22, who is facing several charges including second degree murder and attempted murder.

He remains in custody.
