LOBELVILLE, Tenn. (AP) — Police are examining firearms found at the home of a 15-year-old boy charged with shooting a longtime member of the National Guard at a Tennessee armory.

Tennessee Bureau of Investigation spokesman Josh DeVine, said “several” weapons were uncovered Thursday.

Ballistic experts are studying whether any were involved in Wednesday’s shooting in Lobelville, about 50 miles southwest of Nashville.

DeVine said agents were looking into all leads to piece together possible motives for the shooting. But the analyses of the weapons found at the teen’s house suggested the suspect did not use a gun seized at the armory.

BradenThe suspect gained access to the building and fired several shots, authorities said. One struck Sgt. 1st Class Michael W. Braden of Ripley, Tenn. He served as the Non-Commissioned Officer in Charge of Readiness for Troop A, Support Squadron, 278th Armored Cavalry Regiment. He died later at a hospital.

“This is a sad day for the Tennessee National Guard. We have tragically lost one of our own. Our hearts and prayers go out to Sgt. 1st Class Braden’s wife and children, his extended family and to our Tennessee National Guard family,” said Maj. Gen. Max Haston, The Adjutant General of Tennessee.
