Wanted posters featuring the mug shots of leering criminals trying to stay one step ahead of the law have been a common sight on post office and police station walls. Canada's Most Wanted brings you stories of Canada's most notorious fugitives and the dogged law enforcement officers sworn to bring them to justice: * Kevin Louis Vermett, one of Canada's most wanted fugitives, is the main suspect in the murder of three young men in 1997 after a petty disagreement turned deadly; before the police closed in, he disappeared into the wilderness near Kitimat, BC * James Charles Kopp, an anti-abortionist madman with murder on his mind, is wanted for the 1995 attack on Dr. Hugh Short, who was shot by a sniper through a window of his Ontario home * Machine Gun Molly, a petite woman with a big appetite for money, was the leader of a gang behind a string of bank robberies in Montréal during Expo '67 * The Mad Trapper of Rat River, a recluse wanted for the murder of RCMP Constable Edgar Millen, was finally brought to bay after a wild manhunt through the Canadian Arctic * Ronald Jeffrey Bax is the only suspect in the 1992 slaying of Krystal Senyk, shot at close range by someone lying in wait outside her Carcross, Yukon home; Bax disappeared after the murder never to be seen again.
