Jason Holden and a relative, Shellie Baskins, were arraigned in Clallam County District Court in Port Angeles. A third person, Jesse Holden, was scheduled to be arraigned, but the hearing was postponed until next Thursday to allow him time to find another lawyer.
The Peninsula Daily News reports the three could face nearly a year in jail or a $5,000 fine if convicted.
The Holdens wore ski masks and grabbed Baskins' 4-year-old son April 13 at Carrie Blake Park and drove off in a van.
They later said they were making a video to promote child abduction awareness. Parents and other witnesses were outraged.
