Wendy Gay Riley, 29, of Santa Rosa, California, was last seen on January 13, 1983, after dropping her husband off in downtown Vancouver, British Columbia. She said she planned to visit a friend in North Vancouver but never arrived.

Her green 1978 Honda Civic was found the next day abandoned at Lynn Canyon Park. Wendy was not known to be an outdoor person, and extensive searches turned up no clues. Foul play is suspected and the case remains unsolved.

If anyone knew Wendy, remembers her car at Lynn Canyon Park that January, or has information about her movements that day, please come forward.
