Winnipeg has recorded its fourth homicide of 2012, after an 18-year-old man died from a stabbing early Tuesday in the city's Polo Park area.

Wahbishkanacot Eli Mandamin Jr. was from the Shoal Lake 39 Reserve, a First Nation located about 62 kilometres southwest of Kenora, Ont., family members and band officials have confirmed.

"I was definitely hurt. I couldn't believe it," his cousin, Julian Mandamin, told CBC News. "I guess I still can't believe it happened."

Mandamin was stabbed at the Canad Inns Polo Park on St. Matthews Avenue. He was rushed to hospital in critical condition just after 1:30 a.m. CT and later pronounced dead.

A second male victim, also stabbed in the upper body, remains in stable condition.

Police have taken a number of people in for questioning.

'Real easygoing guy'

Mandamin, who also went by the nicknames "Wahb" and "Wabby," was the son of Eli Mandamin, the current chief at the Shoal Lake reserve, according to band employee Mike Myers.

"He was a real easygoing guy, great sense of humour, always there," Myers said. "If you wanted help with something, he'd be available."

Another cousin, Luke Mandamin, said his relative was accompanying his 21-year-old pregnant girlfriend to a prenatal appointment in Winnipeg.

"He was happy, man. He kept on talking about, 'Yeah, I'm going to be a father' and all that," Luke Mandamin said, adding that he and his cousin were close friends.

"He always came by, hung out … almost every day we always see each other, hang out," he said.

The cousin said he and other family members drove to Winnipeg on Tuesday and tried to see their relative's body at the hotel, but they were turned away.

Stabbing in North End

Meanwhile, police were also called to a stabbing at about 4 a.m. Tuesday near Pritchard Avenue and Aikins Street in the city's North End.

A man was robbed then stabbed in the upper body, police said.

He was rushed to hospital where he remains in stable condition.

Police are looking for two suspects in that incident.
