Summary based on the NamUs case record (MP24288) and 7 other sources
Claudia Mathieu, a 37-year-old woman, was last seen on December 9, 1997, in Dana Point, California. She informed friends that she planned to go kayaking the next day from Dana Point Harbor. On December 10, after her disappearance, her white Toyota RAV4 was found parked at Doheny State Park, with her German Shepherd inside a cage in the locked vehicle. It was highly uncharacteristic of Claudia to leave her dog unattended, which raised immediate concerns.

Claudia’s kayak, a gray "Pongo" with a black seat, was never recovered, and authorities suspect that she may have encountered trouble in the choppy waters of the harbor due to the windy conditions that day. Foul play is not suspected in her case, as it is believed she may have had an accident while kayaking. Despite search efforts, no trace of her has been found, and her case remains unsolved.

Claudia was 5 feet tall, weighed 170 pounds, and had brown hair and green eyes at the time of her disappearance. Her family and authorities continue to seek information that could shed light on her case.

Last Seen: Dec 9, 1997
