    Santoso was last seen on February 19, 2001 at his home in the the Four Cedars Apartments complex located in the 10000 block of Northeast 117th Court, Kirkland, Washington. Neighbors reported hearing a fight in his apartment the night of his disappearance. He was reported missing the following day when a neighbor noticed his door was open. Police found signs of a struggle in his apartment and blood inside and outside the apartment. A back window was broken.

    His car was located the following day parked at the Sea-Tac Airport parking garage. Police found his blood on the passenger compartment of the vehicle. They checked airport-monitoring cameras and flight records but found no trace of him, and his passport has not been used since his disappearance. Santoso immigrated from Indonesia in 1997.

    Santoso was declared dead in June 2002, experts determined from the amount of blood found in his apartment and car that he could not have survived the attack.

    In July 2003 Kim Heichel Mason, a former friend of Santoso was convicted of aggravated first-degree murder, was sentenced to life in prison without the possibility of early release. He has refused to cooperate with police to help locate Santoso's remains.
