PLATTEVILLE, Wis. – The deaths of two graduating seniors at the University of Wisconsin-Platteville, both women, apparently were a murder-suicide. Sources were unclear whether Hallie Helms, 22, or Kelsie Martin, 22, fired the shots. Platteville Police Chief Joseph Hallman has been tight-lipped about the investigation except to say there was no suspect at large. The shooting was in a dorm room. Helms was found dead. Martin was taken to the Platteville hospital and then airlifted 70 miles to the UW-Madison hospital, where she was pronounced dead. UW-Platteville has a policy against guns on campus. The relationship of Martin and Helms was unclear. Helms was a student resident-supervisor in the dorm. Martin also lived in the dorm. A witness reported hearing a loud argument and then a gunshot and a thud.
