South Korea (Chosŏn'gŭl: 남조선), officially known as the Republic of Korea (ROK; Chosŏn'gŭl: 대한민국; Daehan Minguk; listen), is a country located in eastern Eurasia, constituting the southern part of the Korean Peninsula. The word "Korea" is derived from the Kingdom of Goryeo, also known as as "Koryŏ". It shares land borders with North Korea to the north, and oversea borders with Japan to the east and China to the west. Roughly half of the country's 50 million people reside in the metropolitan area surrounding its capital, the Seoul Capital Area, which is the second largest in the world with over 25 million residents.
Born in South Korea, Cho arrived in the United States at the age of eight with his family. He became a U.S. permanent resident as a South Korean citizen. In middle school, he was diagnosed with a severe anxiety disorder known as selective mutism, as well as major depressive disorder. After this diagnosis he began receiving treatment and continued to receive therapy and special education support until his junior year of high school. During Cho's last two years at Virginia Tech, several instances of his abnormal behavior, as well as plays and other writings he submitted containing references to violence, caused concern among teachers and classmates.
In the aftermath of the shootings, Virginian governorTim Kaine convened a panel consisting of various officials and experts to investigate and examine the response and handling of issues related to the shootings. The panel released its final report in August 2007, devoting more than 30 pages to detailing Cho's troubled history. In the report, the panel criticized the failure of the educators and mental health professionals who came into contact with Cho during his college years to notice his deteriorating condition and help him. The panel also criticized misinterpretations of privacy laws and gaps in Virginia's mental health system and gun laws. In addition, the panel faulted Virginia Tech administrators in particular for failing to take immediate action after the first shootings. Nevertheless, the report did acknowledge that Cho was still primarily responsible for not seeking assistance and for his murderous rampage.
