Dennis Paul Samstag, 34, was last seen on July 7, 1994, in Needles, California. He had gone with a friend to the Colorado River, near Wetmore Beach. The two men, who had been drinking, were sitting by the river when Samstag's friend passed out on a boat ramp. When the friend awoke, Samstag was no longer there. Despite extensive searches of the river and its banks, no trace of him was found.
Samstag had several distinctive features, including an eye disorder that caused his eyes to move back and forth, a large mole on the outside of his foot, and a surgical scar on his abdomen. He was last seen wearing swim trunks and no shirt.
Dennis was also classified as a dependent adult, as he was disabled and sometimes wore glasses.
His case remains unsolved, and authorities have found no concrete evidence regarding his disappearance despite thorough investigations. Family and law enforcement continue to seek answers as to what happened to him that day by the river.Last Seen: Jul 7, 1994
