Three people have been found guilty of manslaughter in the stabbing death of a 21-year-old man outside a Vancouver nightclub in 2009.

Tyson Edwards was stabbed to death outside Richards on Richards nightclub on Feb. 1, 2009 and died later in hospital.

The judgment against Patrick Plowman, Sebastian Miazga and Nolan Swallow was handed down Tuesday in B.C. Supreme Court in Vancouver as friends and family in the courtroom clapped and shed tears.

The judge said Plowman, Miazga and Swallow repeatedly punched Edwards in the head, then kicked and punched him after he was limp on the ground.

Edwards was found bleeding from the chest after the assault, and while no weapon was found and witnesses couldn't pinpoint who stabbed him, the judge ruled they were all responsible.

"It's too late for Tyson, Tyson is gone, but it's good to know that at least for awhile, it will be safer for other people in the community," said his mother Carla Edwards.

She says her life has not been easy since her son's death nearly four years ago.

"It's been a complete and total nightmare. It's something you wake up with every day."

A fourth person charged in the case, Kalum Cain, was found not guilty. The judge ruled there was not enough evidence to convict him.

Plowman and Swallow are scheduled to be sentenced on Nov. 14, Miazga on Dec. 19.
