WINNIPEG -- Island Lake RCMP and an army of volunteers are searching a stretch of northern Manitoba for a missing teenager who disappeared almost a month ago.

Sixteen-year-old Tammy Nattaway from Garden Hill First Nation was last seen on July 20, in the community located 475 kilometres northeast of Winnipeg.

Garden Hill First Nation Chief Dino Flett told CTV on Friday that hundreds of volunteers from five communities are scouring the area searching for signs of the teenager.

“We’re still looking,” he said. “We’ve been going day and night trying to locate her.”
