Three more members of the Viper Militia pleaded guilty Friday to explosives charges, six months after they and 10 cohorts were arrested on far more serious allegations of plotting to blow up buildings.
Scott Shero, Henry Overturf and Walter Sanville pleaded guilty to conspiracy to illegally make and possess explosive devices. Sanville also pleaded guilty to two charges of illegally possessing machine-gun parts.
The plea bargain calls for one to nearly three years in prison for Shero, 1 to 1-1/2 years for Overturf, and three to nearly four years for Sanville.
Two other defendants pleaded guilty Dec. 19, and the government said Friday that at least five more were negotiating plea bargains.
