Bloomington police have released new details in the murder-suicide death of an Indiana University student in September. Yaolin Wang, 21, was stabbed multiple times by Chuanlin Xiao before he took his own life. Investigators initially described the two as being in a relationship, but now call that a mischaracterization. Police say Xiao followed Wang from Washington state to Bloomington and was abusive. Wang once described Xiao’s return to Bloomington as a nightmare.
