A preliminary hearing for a grandfather charged with kidnapping his two grandchildren 20 years ago was continued today until May 12.

Marvin Maple, 73, of San Jose, Calif. was charged with kidnapping Christi and Bobby Baskin from their parents Mark and Debbie Baskin in March 1989. Maple was located earlier this year in California and arrested.

Defense Attorney Greg Reed asked to continue the case because he needed more time for his investigation. Maple remains under house arrest.
