HINESVILLE, Ga. (AP) -  A former Army medic originally from St. Cloud has pleaded guilty to destroying evidence in a double slaying to protect what prosecutors say was a militia group operating within the military at Fort Stewart in southeast Georgia.

Former Pfc. Christopher Jenderseck - a 2004 graduate of Apollo -  was allowed to avoid further jail time in the plea deal he agreed to in Liberty County Superior Court. He's among 10 people - eight of them current and former Fort Stewart soldiers - jailed and accused by prosecutors of belonging to a group that plotted to bomb a Savannah park fountain, poison apples in Washington state and assassinate the president.

Jenderseck admitted to destroying clothing, shotgun shells and a cellphone after the December killings of former soldier Michael Roark and his girlfriend, Tiffany York. He agreed to testify against other defendants.
