Casand Neal "Chas" Dewey, 20, an actor who appeared at the John F. Kennedy Center for the Performing Arts, the Wolf Trap and Carter Barron Amphitheatre in the 1990s, drowned June 25 at Isabella Lake near Bakersfield, Calif.

Mr. Dewey was swimming with friends when he apparently tired and drowned in 13 feet of water, according to the Kern County Sheriff's Department. His mother said he had worked the previous morning at a supermarket on the overnight shift and had had inadequate sleep before traveling with friends to the reservoir, about 90 miles from his home in Burbank, Calif.

He had lived in California since 1995, when his family moved from Alexandria. He had recently finished recording an album and had appeared on the Disney Channel show "Even Stevens" and on the MTV series "Undressed."

Mr. Dewey was born in Alexandria and attended Cora Kelly School for Math, Science and Technology. He sang in the choir at Downtown Baptist Church in Alexandria.

He and his twin brother performed for the Shakespeare Theatre, at Carter Barron Amphitheatre and in five operas at the Kennedy Center and Wolf Trap.

A model since he was 6 months old, he appeared in Premiere, Young and Modern, Teen and GQ magazines and in ads for Huggies, Michelin tires and Coca-Cola. He also did runway modeling for Race to Erase MS, Robinsons-May, Calvin Klein, Jean Paul Gaultier, Armani, Versace and Tommy Hilfiger.

Mr. Dewey graduated from Hollywood High School in 2002 and attended Santa Monica College and Glendale Community College, both in California.

Survivors include his parents, Colette Craan of Burbank and Dana Neal Dewey of Jacksonville, Fla.; and a brother, Christian Dewey of Burbank.

Chas Dewey had performed at the Kennedy Center, Wolf Trap and Carter Barron Amphitheater.
