Guns found after Christian & Newsom carjack/slayings don't match up

They can link the guns to the brothers, but prosecutors cannot say either weapon was used to kill Christopher Newsom.
Knoxville Police Department firearms expert Patty Resig testified in Knox County Criminal Court Wednesday that she test-fired two .22-caliber revolvers recovered by authorities in the days following the January 2007 torture slayings of Newsom and his girlfriend, Channon Christian.

Neither proved a definitive match with bullets retrieved from Newsom's body during an autopsy. A dark-colored revolver linked to suspect and accused ringleader Lemaricus Davidson showed the most promise as the slaying weapon, with striations on the bullets showing some characteristics of having been fired from that gun, she said.
