John William Shankland, 59, was last seen leaving his Buffalo, New York, home on June 18, 2017. At that time he was described as a white male with white hair and blue eyes, about 5 feet 8 inches to 5 feet 10 inches tall and 140 to 150 pounds, believed to be wearing a yellow t-shirt with MS Volunteer 2010 on the back and blue jeans.

His vehicle was later found abandoned in Niagara Falls, New York, creating a geographic link but few answers. Authorities have not released the exact location or condition of the car, and it is unknown whether Shankland drove there himself or why he would have gone. The Buffalo Police Department and the New York State Park Police in Niagara are the investigating agencies, and no significant public leads have been reported.

The car remains the last known piece of physical evidence connected to him. Did anyone in the Buffalo–Niagara area see John or his vehicle around June 18, 2017?
