A Purdue University student was charged with one count of murder in the fatal stabbing of his roommate in their dorm on the West Lafayette, Indiana, campus last week.

During a hearing Thursday, the Tippecanoe County Prosecutor’s Office formally charged Ji Min Sha, 22, with the killing of Varun Manish Chheda, 20, a senior from Indianapolis, who was in his third year of college and was graduating early.
