Clemons was employed as a truck driver in 2000. He was a resident of the New York City borough of Brooklyn at the time. Clemons was scheduled to deliver a truck to the Milwaukee, Wisconsin area in June 2000. He became stuck in the mud near Rochester, Minnesota on June 17, 2000 and was helped back onto the road by the police, who gave him directions to Milwaukee. Clemons never arrived at Milwaukee, however. He was last seen walking away from the vehicle near Interstate 90 and Interstate 43 in Beloit, Wisconsin. Clemons does not usually make deliveries; his job is to maintain the shipping yard for the trucking company, which had employed him for ten years prior to his disappearance. However, Clemons's boss states that he was anxious to make the delivery to Milwaukee. He has not been seen or heard from since June 17, 2000.
