Tyler Arkinson was last seen at a house party when he disppeared. (Family photo/RCMP)Search teams have resumed a desperate search for a missing 14-year old boy on Sagkeeng First Nation, north of Winnipeg.

Tyler Arkinson hasn't been seen since he left a house party early Sunday morning, and rumours are circulating through the community that he might have been involved in a fight before he went missing.

People are trying not to fear the worst but it's not easy because so many rumours are being spread, said Arkinson's uncle, Camille St. Croix.

"Different people [are] saying that he's been here and seeing him there, and then you talk to them and they're just like 'no, people are talking crap to their friends,'" he said. "I don't know."

A community meeting was held Wednesday with family members, RCMP, and representatives from the Office of the Fire Commissioner and Manitoba Search and Rescue.

The meeting was held to discuss leads and any other information about Arkinson that might help narrow the search.

George Leonard, who heads up a private group called Manitoba Search and Rescue, said Sagkeeng's chief also put out a special plea for information on the band radio station.

"Manitoba Search and Rescue is full of aboriginal people. When we work closely with chief and council, it is easier for us to extract information," he said. "We want to find this kid. Just tell us the information — that's all we need to know. "

St Croix described Arkinson as a happy person who got along with everyone. He hopes the search turns up clues today, because the weather is expected to turn extremely cold overnight.

Environment Canada is calling for a low of about –22 C and only a high of –7 C on Thursday. Family members said Arkinson was not dressed for that kind of cold.

"It'd be great if we could search the whole community here — cars, sheds, everything," St. Croix said.

Arkinson's family reported him missing to authorities after they did their own cursory search of the area and failed to locate him.

A team of volunteers, RCMP and members from Manitoba Search and Rescue began searching Tuesday, combing through wooded areas in the community, about 100 kilometres northeast of Winnipeg.

They also scoured a stretch of land alongside Highway 11, searching water-filled ditches.

Approximately 80 people — including 35 RCMP officers and four canine units from Manitoba Search and Rescue — resumed the search Wednesday.

About half of the people explored the region near Arkinson's mother's home, where he was living at the time.

St. Croix said the teen is close to his mother and always checked in by phone when he was going to be away.

"His mother is very upset, very traumatized," he told CBC News on Tuesday.
