Glad he was caught, hopefully they find the other 3 firearms.  These aren't technically "assault rifles". Assault rifles by true definition are fully automatic, or have selector switches to go from semi-auto to burst fire to fully-auto. That is basically the only functional difference so I'm not going to get too caught up in semantics - but wanted to point it out never-the-less.  The Noveske rifles are AR-15 type rifles, which are semi-auto (1 round fired per pull of the trigger).  The Century Arms are likely an AK-47 type rifle, and the Raven is an AR-15 - both semi-autos as well.
