Dennis Paul Samstag, 34, disappeared on July 7, 1994, after going to the Colorado River near Wetmore Beach in Needles, California, with a friend. The two had been drinking; the friend passed out on a boat ramp and when he awoke Samstag was gone. Extensive searches of the river and banks turned up no trace.

Samstag was a dependent adult who was disabled and sometimes wore glasses. Distinctive features include 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 in swim trunks with no shirt.

There is no concrete evidence explaining what happened that day and the case remains unsolved. If anyone who was at Wetmore Beach or the Colorado River on July 7, 1994, remembers seeing Dennis or has information about his disappearance, please share what you know.
