$20M Lotto 6/49 winner to claim prize in Kamloops

The winner of Wednesday's Lotto 6/49 jackpot is expected to pick up his or her cheque for $20,223,182.30 this afternoon in Kamloops.

The winner's identity has been the source of much speculation after lottery officials announced the ticket was sold in the town of Revelstoke, which has a population of roughly 7,000.

Witnesses reported seeing a clearly shaken man check the winning ticket at a Vernon mall on Thursday.
