Details of Disappearance
Santoso was last seen at his apartment during the evening of February 19, 2001. The apartment is located at at the Four Cedars Apartments in the 10000 block of northeast 117th Court in Kirkland, Washington.

Later, the front door to the apartment was found open and a cinder block had been thrown through one of the windows. Police found a great deal of blood blood and signs of a burglary inside the residence, and more blood outside the apartment building, but there was no sign of him.

The vehicle had a substantial amount of Santoso's blood inside and a bloody palm print on the outside. There is no indication that Santoso took a flight out of the airport, and his passport has not been used since his disappearance.

Later, a knife covered with Santoso's blood was found in Newcastle, Washington, off Interstate 405.

A photograph of Mason is posted with this case summary. He is also known as Hiiro Takashi Riser and/or Brian Allen Mason. Santoso claimed Mason demanded he write a check for $700 to pay a drug dealer before he eventually released him.

Mason was charged with first-degree kidnapping and robbery in connection with the incident. He admitted to choking Santoso, but said it was to ward off unwanted sexual advances. Santoso, who is bisexual, told police that he and Mason had once had a sexual relationship. Two other witnesses confirmed it, but Mason denies it.

Santoso got a restraining order to keep Mason away from him after the assault. He was afraid for his life after reporting Mason to the police, and slept with a hammer in his bedroom and a knife under the couch. He told his friends that he wanted to move to Portland, Oregon to get away from Mason.

In April of 2001, two months after Santoso's disappearance, Mason was charged with first-degree murder in connection with his case.

Authorities say Mason broke into Santoso's apartment, stabbed him to death, disposed of the body, and left Santoso's car at the airport to make it appear as if he had left the country. The motive was probably to prevent Santoso from testifying against him in connection with the assault and robbery.

Madrid claims Mason disappeared for three days after Santoso vanished, and when he returned, he confessed to her that he had killed Santoso and decapitated the body to make identification more difficult before he disposed of it in an unknown location. He said he had accidentally stabbed himself in the thigh during the attack.

Mason's blood and fingerprints were not found in Santoso's apartment, though they were in Santoso's Mustang. The bloody shoe prints inside the apartment were too big to be from his feet. In addition, the palm print in blood found on the outside of Santoso's car was not Mason's.

Santoso remains missing. He is an Indonesian immigrant who moved to the United States about five years prior to his disappearance. He has no family members in the States, but was helping to support a large family back in Indonesia. He was employed as a nursing assistant in 2001.

Foul play is suspected in his case due to the circumstances involved.
