Excerpt
Born on January 18th, 1984, at the time of his rampage, Cho was a senior-level undergraduate student at Virginia Polytechnic Institute and State.

In middle school, he was diagnosed with a severe anxiety disorder known as Selective Mutism, as well as a major depressive disorder. After his diagnosis, he began receiving treatment, and continued to receive therapy and special education support until his junior year of high school. Two students complained to authorities about the behavior of Cho when they contacted them in separate incidents in 2005. Police questioned Cho and he was sent to a mental health facility, but no charges were filed against him.

Preliminary Activities

General District Court records show that a Montgomery County magistrate ordered Cho, then twenty-three years old, to undergo a mental evaluation in December of 2005. The magistrate found probable cause that Cho was “mentally ill,” and an “imminent danger to him and others,” seriously mentally ill enough as to be unable to care for himself.

The police spoke with acquaintances of Cho and became concerned that he might be suicidal. Officers suggested to Cho that he speak to a counselor, and Cho took their advice. Based on his meeting with the counselor, Cho went to the police department voluntarily; a temporary detention order was obtained, and Cho was taken to a mental health facility, the Carilion Saint Albans Behavioral Health Center.

During Cho's last two years at Virginia Tech, several instances of his abnormal behavior, including plays and other writings he submitted, contained references to violence that caused concern among teachers and classmates. Detectives believe that Cho Seung-Hui was obsessed with eighteen year old student Emily Hilscher, one of his first two victims. Cho apparently had become infatuated by her.
The Massacre

Dressed more like a boy scout than a mass murderer, Cho arrived at Hilscher’s dormitory room early Monday morning on April 16th. It is unclear whether Emily Hilscher had responded to her killer's approaches. Cho, jealous of Emily's boyfriend, gunned her down. Another student, Ryan Clark, rushed to help after hearing his neighbor arguing with Cho, and the twenty-two year old died alongside her.

Cho then went back to his room where he used his computer to assemble an 1800 word written statement, videos, and photographs of himself, that he then packaged up and mailed for overnight delivery to NBC news in New York via the small post office near the main gates of campus. The package was time stamped at 9:01 a.m. He then went back to his dorm room and collected his weapons.

Around 9:45 a.m., two hours after his first killings, Cho entered Norris Hall after chaining the three main exits to the building shut. He placed a note on at least one of the chained doors, claiming that any attempts to open the door would cause a bomb to explode. In Room 206, professor G.V. Loganathan was teaching advanced hydrology when he was shot and killed by Cho along with nine students; another two were injured.

In Room 207, professor Christopher James Bishop was teaching Elementary German when Cho burst into the room, shot the professor, and killed four students in the first row of the classroom, wounding another six.

In the stairwell, Cho fired at Janitor Gene Cole and missed five times, according to the janitor. Cho then moved on to Norris 204 where Cho was initially prevented from entering by barricades erected by instructors and students. Professor Liviu Librescu, a Holocaust survivor, forcibly prevented Cho from entering the room. Librescu was able to hold the door closed until most of his students escaped through the windows, but he died after being shot multiple times through the door. Student, Nicole Regina White, was also killed while another student was injured.

Cho proceeded to Room 211 where Professor Jocelyne Couture-Nowak was teaching Intermediate French. Again, people attempt to block the door, but the Professor and another student were killed.

Students, including Zach Petkewicz, barricaded the door of room 205 with a large table after substitute professor Haiyan Cheng and a student saw Cho heading toward them. Cho shot several times through the door but failed to force his way in. No one in that classroom was wounded or killed.

Hearing the commotion on the floor below, Professor Kevin Granata brought twenty students from a nearby classroom into a third-floor office where the door could be locked. He then went downstairs to investigate and Cho fatally shot him.
