A Mason County District Court jury found former Port of Shelton Commissioner Jack Miles guilty of driving under the influence of alcohol this week. The jurors rendered their decision after a three-day trial that began Monday. During the early morning hours of February 27, 2011, Miles was the driver of a car that ended up in a ditch on Shelton Matlock Road about a mile west of the City. Miles failed a field sobriety test and was taken to the Mason County Jail where he was tested by a breathalyzer. That test showed blood alcohol content (BAC) readings of 0.11 and 0.10 which are above the legal limit of 0.08. Miles claims a diabetic issue caused him to fail the field sobriety test and his lawyer argued the breathalyzer malfunctions and produces high BAC readings on those with diabetes. Testimony on this malfunction was not allowed during trial. Miles says he will appeal the conviction and says there are also plans to pursue misconduct charges against the presiding judge who Miles says violated his rights and allowed false witnesses statements.
