Vaska Yarrow has a long history of criminal activity. Vaska has been implicated in several cases of assassinations going back 10 years. All victims had a single fatal gunshot wound to the middle of the forehead. A lack of live witnesses and their refusal to confess even under extreme persuasion allowed them to elude incarceration. They were finally apprehended for an unexpected spate of brutality in a run down corner of the Selphasi orbital colony. It took the extended efforts of an entire squad of soldiers to subdue Vaska. Although Vaska unsurprisingly has refused to comment on the reason for this outburst, a stash of KRL was found nearby in a hidden compartment under the corpses.
