-- "A former University of Wisconsin-Madison graduate student, Arvin Raj Mathur, 32, threatened students, staff members and professors at the university, telling some of them via email before he travelled to the U.S. last week that he planned to kill their children, according to court documents. 'I will murder their children. Call the police and a lawyer, otherwise, I will kill their children and hide their flesh inside of their burger meat.'" --
