Police have charged a University of North Carolina graduate student with first-degree murder in the fatal shooting of a faculty member that caused a campus lockdown during the search for the gunman. Thirty-four-year-old Tailei Qi is due in court later Tuesday for an initial hearing in the Monday killing of Zijie Yan inside a science building on the Chapel Hill campus. In addition to the murder count, he is charged with having a gun on educational property. Yan is listed on the school’s website as an associate professor in the Department of Applied Physical Sciences, while Qi is listed as a graduate student in Yan’s research group.
