Dave McKenna, 48, disappeared from Willow, Alaska on July 28, 1993. Known to friends and family by nicknames including Big Dave, Uncle Dave and Mr. Smilely, he was last linked to an abandoned 4-wheeler and trailer found at 4 Mile Road. The Alaska State Troopers opened the investigation on August 2, 1993, and the case is cataloged in NamUs as MP54268.

Reports describe him as having a limp and a scar on his left forearm. Clothing at last sighting is listed as blue jeans and a gray and white plaid shirt, although some accounts say he may have been shirtless. With no further witnesses or physical evidence, investigators have not been able to resolve whether his disappearance was an accident, a wilderness misadventure, or involved foul play.

Does anyone who lived in Willow in July 1993 or who might have seen a 4-wheeler and trailer on 4 Mile Road that day have information to share?
