Richard Uden was 11 when he and his family disappeared after leaving Riverton, Wyoming, on September 12, 1980, to meet his mother’s ex-husband for a hunting trip. Virginia Uden and Richard’s younger brother, Reagan, were with him and the three were never seen alive again.

Investigators found the family’s 1973 Ford station wagon on October 4, 1980, near Wind River Canyon; the vehicle had been covered with pine branches and contained blood. Decades later, in 2013, Gerald Uden confessed to killing Virginia, Richard and Reagan, saying he shot them with a .22 caliber rifle, placed their bodies in barrels and dumped the barrels into Fremont Lake. Their remains have not been recovered.

The confession closed many questions about what happened, but without recovered remains some details remain unresolved. Does anyone have information about the Uden family’s movements in September 1980 or about searches near Fremont Lake?
