Here’s a news item from the Associated Press: BOISE, Idaho (AP) — The Idaho Supreme Court has affirmed a northern Idaho judge's decision to toss out blood draw test results in a fatal crash case because police failed to get a search warrant. The court in a decision released Tuesday ruled that Kyle Rios withdrew his implied consent to blood alcohol testing by refusing to sign a consent form. Rios was charged with vehicular manslaughter, leaving the scene of a fatal crash and drunk driving following the Dec. 1, 2013, crash that killed Paul W. Stuk of Peck. The blood draw found that Rios had a blood alcohol content of 0.263 percent, three times the legal limit. Rios has pleaded not guilty to vehicular manslaughter and leaving the scene of a fatal crash.
