A Canadian man’s lottery dream turned into a legal nightmare after his girlfriend allegedly cashed in his $3.6 million winning ticket and then disappeared from his life.Lawrence Campbell of Winnipeg claims he purchased the 5 million Canadian dollar ticket but was unable to collect the prize himself because he had lost his wallet and lacked proper ID. Trusting his longtime partner, Krystal McKay, he asked her to claim the winnings on his behalf.But instead of sharing the windfall, McKay allegedly cut ties with Campbell just days after receiving the money, prompting him to file a lawsuit to recover what he says is rightfully his.Campbell’s lawyer told CTV News that the couple had been living together and were in a “loyal, committed and promising romantic partnership” when he entrusted her with the winning ticket.According to the lawsuit, less than two weeks after claiming the prize, McKay failed to return to the hotel room they’d been sharing. Campbell says he tracked her down only to find her in bed with another man.“She ghosted him, refused to take his calls or answer his messages, she blocked him on her social media accounts, and even took out a protection order,” his lawyer alleged.McKay, for her part, has denied the allegations and is expected to respond in court.
