Christopher McKay, 36, disappeared from Wichita Falls, Texas, on June 30, 2015. He was last seen driving his truck; the vehicle was found abandoned at Williams Park on July 1, 2015. McKay is described as 6 feet 4 inches tall, about 260 pounds, and has distinctive tattoos on his elbow, neck, and bicep that have been shown on missing person flyers to aid identification.

His family is particularly worried because he has a medical condition that requires daily treatment. Local tips have come in over the years, but none have produced a resolution and the case remains unsolved. If anyone saw Christopher around the end of June 2015 or has information about his truck being left at Williams Park, please come forward with what you know.
