Authorities in two states say Brian Karl Peters Jr., 33, is no novice when it comes to allegedly committing acts of violence. In 2012, he pleaded guilty to simple assault and criminal mischief after Hellam Township Police arrested him the year before. Charges of aggravated assault and harassment were dropped at a pre-trial conference. Not only that, but at the time of Runkle's death, there was already a warrant for Peters' arrest out of Melbourne, Florida, on charges of first-degree premeditated murder, tampering with evidence and criminal use of personal identification information, according to the Brevard County Sheriff's Office in Florida. In Tuesday's homicide, West Manchester Township Police have charged Peters with criminal homicide, and murder of the first, second and third degree, according to online court dockets.
