A Winnipeg courtroom heard dramatic testimony from a young man who was injured in a 2009 shooting that killed two of his friends during a house party.

Sporting a bandage on his right arm, Kyle St. Germain told the court on Wednesday that he is still recovering from the shotgun wound he suffered on Dec. 5, 2009.

St. Germain was 17 years old at the time of the shooting, which happened at a house party he was attending on Martin Avenue in Winnipeg's Elmwood neighbourhood.

Tyler "T.J." Hawula and Matthew Reynolds, both 18, were killed in the shooting.

Charged with first-degree murder and attempted murder in connection with the shooting are two men who were 16 and 17 years old at the time and cannot be named under the Youth Criminal Justice Act.

On Wednesday, St. Germain testified that everyone was having a good time when he arrived at the house party that night.

He said two guests then started bragging that they were in a gang, with one of them showing off a large knife and claiming that he was a member of the Crips street gang.

St. Germain told the court that he told the two teens, "There's no gangs here, so we want no problem."

Hawula, who was hosting the party, also raised concerns about the the two guests, St. Germain said.

St. Germain testified that he was later sitting on a couch in the living room, talking with Hawula's mother, when a man armed with a firearm burst in and began shooting.

"He didn't stop at all, he just swung and shot," St. Germain said, adding that he initially did not notice he had been injured.

He said he could only see half of the shooter's face before he fell to the floor.

St. Germain also told the court that he saw Hawula and Reynolds on the kitchen floor moments later.

Reynolds's mother fought back tears and at one point left the courtroom during St. Germain's testimony.

The trial resumes on Thursday.
