UNC-Chapel Hill graduate student Tailei Qi, 34, has been charged with first degree murder in Monday’s on-campus shooting of Zijie Yan, 38, an associate professor in the university’s Department of Applied Physical Sciences. Yan, who was identified as the victim Tuesday, served as academic advisor to Qi. The two men co-authored research papers – one published just last month – and worked closely as part of a department research group over the last year. In Twitter posts over the last year, Qi expressed frustration with his work, his graduate student colleagues and his “PI” or principal investigator, usually a faculty member assigned by the university to work with students on research projects. It is not yet clear whether Yan was the subject of these social media posts, which were often vague, cryptic and frequently parts of partially deleted threads. https://ncnewsline.com/2023/08/29/victim-identified-suspect-charged-in-fatal-unc-chapel-hill-shooting/
