Vital Statistics at Time of Disappearance
Details of Disappearance
Yamamoto was last seen Sept. 29 in Bothell, Wash. He is believed to have taken an inflatable kayak out on Lake Washington. He lived alone, and talked to his family only at Christmas. His family was notified when Yamamoto did not pay his November rent. Yamamoto always paid his rent three months in advance. In October Yamamoto's abandoned car was located by a security guard at Denny Park and eventually towed and impounded on Oct. 14. Officials searched the vehicle, finding no signs of foul play. The towing company that impounded Yamamoto's car found a map in his car with hand-written instructions on how to get to the park. One thing recovered of interest was an empty, inflatable kayak bag. The discovery suggested to his family that Yamamoto had paddled off in a kayak on Lake Washington. A kayak or paddle has not been found. He was quiet and kept to himself, so the majority of the people around him didn't notice he was gone.
Yamamoto was raised in Tokyo, Japan. Yamamoto later graduated from the Brooks Institute of Photography in Santa Barbara, Calif. where his parents eventually retired. Yamamoto later moved to Washington State.
