Valley man challenges 2003 conviction for making ricin
A Spokane Valley man serving 10 years in federal prison for making a deadly poison is asking to have his sentence and conviction overturned because one of the government’s expert witnesses was later fired for misconduct in other criminal cases.
Kenneth Olsen, a former computer programmer and part-time massage therapist, is scheduled for a hearing early next year on his request to set aside his 2003 jury conviction for making ricin, one of the deadliest chemical poisons known. The conviction has already been upheld by the 9th U.S. Circuit Court of Appeals, although his original sentence was remanded and reduced.
After ricin was found at Olsen’s work station at Agilent Technologies in Liberty Lake, federal prosecutors accused him of researching various toxins and making ricin from castor beans as part of a plan to poison his wife. But his defense attorneys argued Olsen was merely curious about chemistry and was using the beans to make castor oil for massage oils. His wife said she didn’t believe he would ever try to harm her.
Among the prosecution witnesses was Arnold Melnikoff, at the time the head of the Washington State Patrol crime lab, where some of the evidence in the case was sent for testing. Months before Olsen’s trial, a Montana rape case in which Melnikoff had served as the key witness on scientific evidence was overturned because his testimony was not based on sound science. The man who was wrongly convicted in that case was freed after 15 years in prison.
Olsen’s trial attorneys were not told the full extent of investigations involving Melnikoff’s possible misconduct, the appeal contends. Melnikoff was fired from the Washington State Patrol in March 2004.
It also says one juror was much more familiar with the case than he revealed during the pre-trial interviews, and had already formed an opinion that Olsen was guilty.
Federal prosecutors have until Dec. 11 to respond to grounds cited in Olsen’s appeal, and a hearing in U.S. District Court is scheduled for Jan. 29.

I empathise with this mans plight not because I agree with his case. It has to do with how Spokane and Spokane County metes out “justice”. Mr. Hal Moos of the Booktraders in Garland was accused of being a Pedophile. This was on the front page of your paper. It was all over KREM News and the other Yahoo news Nertworks in this town. It destroyed his business, subjected him to constant Harassment by Police, destroyed his business,,including Broken windows and robberies. This is a 75+ year old model citizen all his life. He has now been subsequently found not Guilty and do you think that there is one SINGLE retraction in Spokane. NO! Spokane is rotten like the rest of America. Unless it is Scandal, it is not newsworthy.
