Summary based on the NamUs case record (can2017044551) and
1 other sourceMark Trizanto was 42 years old when he was last seen in Toronto, Ontario, on August 4, 2017. According to the Royal Canadian Mounted Police’s Canada’s Missing case record, Mark was observed at approximately 1:00 p.m. near Roncesvalles Avenue and The Queensway. He was a male born in 1974 and was described as Black, approximately 5 feet 8 inches tall and weighing about 130 pounds. His build was described as slender or thin.
That afternoon became the starting point of a missing-person investigation after Mark could no longer be located, leaving investigators with the difficult task of determining where he went after he was seen in that area of Toronto.
The clothing and belongings Mark had with him provide some of the most important identifying details available from the investigation. He was reported to be wearing black jeans and a blue T-shirt, and he was carrying a black backpack. These details, together with his physical description, were included in the national missing-person record so that members of the public who may have encountered him could recognize him. The area where Mark was last seen is specifically identified as being near Roncesvalles Avenue and The Queensway, and the available official information places him there at about 1:00 in the afternoon. The publicly released record does not describe what Mark had been doing earlier that day, where he intended to go afterward, whether he was traveling on foot or by another means, or who, if anyone, may have spoken with him around the time he disappeared. No additional sequence of movements after that sighting is provided in the national case profile.
The absence of publicly released information about Mark’s movements after the Roncesvalles Avenue and The Queensway sighting leaves a significant gap in the timeline. The official record does not identify another confirmed sighting after approximately 1:00 p.m., nor does it describe the discovery of personal belongings, a vehicle, financial activity, telephone activity, or any other event that would establish where Mark went next. It also does not publicly identify circumstances suggesting why he disappeared. As a result, the known story of his disappearance remains centered on a relatively small collection of confirmed facts: Mark was in Toronto, he was seen near that intersection during the afternoon of August 4, 2017, and investigators subsequently sought information that could help determine what happened after he was last observed.
The Toronto Police Service Missing Persons Unit is identified as the investigating agency, with the police case reference 2017-1401237.D11. Canada’s Missing also lists the national case reference as 2017044551. Authorities have asked anyone with information concerning Mark’s disappearance to contact the Toronto Police Service Missing Persons Unit, while information may also be supplied anonymously through Crime Stoppers. The national record remains an important means of keeping Mark’s photograph, description, clothing information, and last-known circumstances available to the public in the hope that someone may remember something significant about seeing him or interacting with him around the time he disappeared.
Mark Trizanto’s case is ultimately defined by how little is publicly known about what happened after an ordinary afternoon in Toronto. At age 42, he was last seen near Roncesvalles Avenue and The Queensway at approximately 1:00 p.m., wearing black jeans and a blue T-shirt and carrying a black backpack. He was described as 5 feet 8 inches tall, about 130 pounds, and slender in build. Beyond that last confirmed point, the publicly available official record offers no detailed account of his subsequent movements or circumstances. The unanswered question remains what happened after Mark left the place where he was last seen, and even after the passage of years, information from someone who encountered him that day could help investigators better understand the events surrounding his disappearance.Last Seen: Aug 4, 2017
