A Cashmere soldier, suspected of murder in Georgia and accused of being the founder of a militia group that was plotting to kill President Obama and overthrow the U.S. government, purchased 15 firearms, including several semiautomatic rifles, at High Mountain Hunting Supply in Wenatchee in September 2011. Sgt John Kruse with the Wenatchee Police Department told the Seattle Times that it was the gun purchase along with a suspicious relative that prompted their investigation into Army Pvt. Isaac Aguigui. The unnamed relative told police that Aguigui's wife, who was also a soldier, and the couple's unborn child had died under suspicious circumstances in July 2011 at Fort Stewart, Ga., where they were stationed. The relative also was concerned that Aguigui had purchased more than a dozen firearms, including assault-style weapons, from High Mountain Hunting Supply in Wenatchee. Aguigui is among four current and former soldiers who are charged with killing a former Army comrade, Washington state native Michael Roark, and his girlfriend to protect the secrecy of the anarchist militia group they formed. Prosecutors in georgia say the group was plotting to blow up a dam in Washington and poison the state's apple crop.
