John B. Krywokulski was 23 when he was dropped off for his construction shift at the Red Maple Inn on Rainbow Boulevard in Niagara Falls, New York, on May 7, 2019 — the last time anyone saw him. He is described as a white male between 6 feet 2 inches and 6 feet 4 inches, 240 to 260 pounds, with brown hair and brown eyes. He was wearing a black hoodie over a black t-shirt, blue jeans, and brown work boots that may have had white plaster on them.

Shortly after he was last seen his cell phone was turned off. A ping from the device placed it at 8219 Niagara River Parkway in Ontario, Canada, a location along the Niagara River downstream from where he vanished. Canadian Customs records show no official crossing by him. The Niagara Falls Police Department opened an investigation and the case is listed with the National Missing and Unidentified Persons System, but there have been no public breakthroughs and no contact with family or friends since May 7, 2019.

If anyone was in the area that morning or has information about John’s movements, clothing, or the phone ping near Niagara River Parkway, please come forward.
