John Peter Lioudakis, 39, of Toronto, was last seen the morning of Thursday, May 23, 2013, at about 6:30 a.m. at Toronto Pearson International Airport. He is described as a white male with an olive complexion, 6 feet 3 inches, 220 pounds, muscular build, brown hair and brown eyes, with a small iguana tattoo on his lower-left calf, a chin piercing and a vertical scar on his right forearm. When last seen he wore a grey Jack Jones T-shirt, blue jeans and white running shoes.

Police records show he did check into the Crowne Plaza Hotel in Mazatlán the day after he was seen in Toronto and stayed about a week before checking out; there are no records of him returning to Canada and his scheduled return flight on May 31, 2013, was missed. A text he sent that included a map of an area on the Mazatlán–Culiacán highway has been noted in the investigation. The Toronto Police Service issued a missing person report on June 21, 2013, and expressed concern for his safety.

Family and friends maintain a Facebook page and a website seeking information. Does anyone who traveled in or around Mazatlán or the Mazatlán–Culiacán highway in late May 2013 remember seeing John or his vehicle?
