Holly Ann Grigsby will go down in the annals of history not just for her murderous crimes but for her radical beliefs that she claims are "misunderstood." Grigsby and her ex-boyfriend David "Joey" Pederson went on a ten-day killing spree that spanned three states in 2011. Because of this, they're going to serve a sentence that will span the of their natural lives. According to the judicial record, there were four murder victims because of the couple's treacherous acts, but there are far more victims who have to suffer, mourn, and go on living without their loved ones in their arms as a direct result of their actions. We don't know much about Holly's childhood, or what kinds of things may have happened to her in her early years to influence her behavior. From a genetic and demographic background, there aren't very many white female serial killers at all. Holly is far from the only killer woman alive, there are a few, but how does she compare to other known female offenders?
