Haas was last seen at the R&R Grocery on Greasy Ridge Road in Scottown, Ohio at 3:00 p.m. on July 15, 2010. At the time of his disappearance, he was carrying his wallet, a keychain with his name on it and a silver cigarette lighter. He also had a blue t-shirt but wasn't wearing it. Haas was supposed to be on his way home, but never arrived. He has never been heard from again. On July 16, his tan four-door 1992 Honda was found abandoned on a rural road at Johns Creek.

Haas had dated the same woman for fifteen years prior his disappearance and acted like a father to her son; she stated he was well-liked, had no enemies and wasn't involved with drugs. He has three sons of his own and worked as a laborer at the time he went missing. Because Haas's disappearance is uncharacteristic of his behavior, his loved ones fear he came to harm. His case remains unsolved.
