Dennis Cyncor-McMillan, 17, disappeared during a late-night swim at Davenport Beach in Santa Cruz County on March 9, 2009. He and friends had been camping after a barbecue; around 4 a.m. he and another teen swam from shore toward a rocky outcropping about 70 feet out. The companion returned but Dennis did not.

Though described as a strong swimmer and a member of the Capitola Junior Lifeguards, conditions were severe: ocean temperature near 50 degrees Fahrenheit and swells as high as 12 feet. Large-scale search and rescue operations by California State Parks, the U.S. Coast Guard, and local agencies covered roughly 50 square miles of ocean that day but found no trace. The search was called off later the same day.

Dennis was a senior at Los Gatos High School and played wide receiver for the football team. He is presumed to have drowned, but his body was never recovered. If anyone knew Dennis, his last movements at Davenport Beach, or was at the beach that night, please share information that might still help clarify what happened.
