What environmental and interpersonal interactions are relevant in this case?
Case: On April 16, 2007, 23-year-old Seung-Hui Cho killed 32 people on the campus of Virginia Tech University before turning the gun on himself. In the months leading up to the murders, Cho had numerous encounters with mental health professionals. He had been declared an “imminent danger to self or others as a result of mental illness” on a temporary detention order from a Virginia District Court. Two students had filed complaints against him for bizarre phone calls and emails he had sent. Another student, his former roommate, called campus police stating that Cho could be suicidal. A poetry professor at the school recalled that he was “menacing” in class, and other students stopped attending after he began photographing them. This professor later removed Cho from her class and worked with him one on one. She also reported that the content of his poems and other writings was disturbing and seemed to have an underlying threat. A South Korean national, Cho moved with his family to the United States at the age of 8. As a youngster, he was diagnosed with depression and selective mutism, a condition associated with social anxiety, and received therapy and special education services as a result. He was a successful elementary school student, but by middle school he was apparently subject to mockery from fellow students because of his speech abnormalities, his accent, and his isolation.
