The FBI is seeking information on a parental kidnapping case in which the suspect may have sailed to Hawaii from Seattle with a missing 9-year-old boy.

Jeffrey Ford Hanson, 46, set sail from Seattle on Sept. 4 with his son, Billy Hanson, in a sailboat called Draco, and neither has been seen since.

The FBI in Seattle consulted with the Coast Guard, which said that based on the type of boat and Hanson’s sailing abilities it is possible for him to have sailed to Hawaii, American Samoa, Guam, the Northern Mariana Islands and other Pacific islands.

Hanson, a known drug abuser with a volatile personality, is the noncustodial parent and is wanted by the FBI for international parental kidnapping.

Honolulu FBI Special Agent Tom Simon said, "Our focus is helping the agents at the Seattle FBI recover Billy safely, so he can go back to his mom where he belongs.

"Hawaii and the islands of the Pacific have a vibrant sailing and nautical community, and we are appealing to that community to be on the lookout for this sailboat and contact authorities with leads."
