Claudia Mathieu, 37, was last seen December 9, 1997, in Dana Point, California. She told friends she planned to go kayaking from Dana Point Harbor the next day. On December 10 her white Toyota RAV4 was found parked at Doheny State Park with her German Shepherd inside a cage in the locked vehicle — an uncharacteristic move that raised immediate concern.

Claudia’s kayak, described as a gray Pongo with a black seat, was never recovered. Authorities suspect she may have gotten into trouble in the harbor’s choppy, windy conditions, and foul play is not suspected; however no trace of her has been found despite searches. She was 5 feet tall, 170 pounds, with brown hair and green eyes.

Does anyone who knew Claudia or who was on the water at Dana Point Harbor that weekend have information that could help clarify what happened?
