State District Judge Ron Ware threw out a jury's second-degree murder verdict against a man accused of killing a Marine. Yesterday Judge Ware threw out a jury's second degree murder verdict, substituted a verdict of manslaughter and sentenced Bryce Perkins to serve 30 years in prison — 20 of which are to run without the benefit of parole — because the crime was committed with a firearm.  Twenty-year-old Daniel Gueringer was killed while attempting to break up a fight at a party in 2009.  Judge Ware said he felt Perkins did not have the specific intent to kill or inflict great bodily harm on anyone when he fired the gun. The shots killed Gueringer, a Marine who was home on leave.
