Nunavut student 'vanished,' say Kingston police

It's been a week since a young Pangnirtung, Nunavut, man went missing in Kingston, Ont., and police and family have no leads as to his whereabouts.

Ken Kilabuk, 22, is studying at St. Lawrence College.

Kingston police Det. Frank Howard said they don’t have much to work on.

"We’re very concerned, the parents are very concerned, and right now really, he more or less vanished on the night of the 15th. We have run down his bank cards and credit cards, and there's no activity. And that's a huge concern to us," he said.

Howard said police haven't ruled out foul play.

Kilabuk’s mother Sandra says it's not like her son to be out of touch for so long.

"This week has been the hardest week of my life, not knowing where my son is," she said. "We have this agreement between myself and my son that I have to hear from him every single day, either by phone or by text. And the last time I heard from him was Monday night, the night of his disappearance."

Kilabuk's girlfriend reported him missing after she hadn't heard from him.

Howard said they’re trying to figure out if something happened to Kilabuk, or if he took off on his own.

Howard said police are asking the public for any help in finding Kilabuk.
