Oikos University shooting

Goh died on March 20, 2019, while in custody at California State Prison-Sacramento. The Sacramento County coroner's office investigated the cause of Goh's death. As of April 9, 2019, the coroner did not release the results of its investigation.

In May 2017, Goh pleaded no contest in the shooting. On July 14, 2017, Goh was sentenced to seven consecutive life sentences plus 271 years in prison, all without any possibility of parole. In March 2019 Goh died in prison.

On August 26, 2014, an Alameda County grand jury indicted Goh on seven counts of murder and three counts of attempted murder but as of September 9, 2014, he was still assessed as mentally incompetent for trial. During a hearing on December 2, 2015, Goh expressed his wish for the death penalty, though the attorneys on both sides are unsure whether he feels genuine guilt or still has delusions.

Goh's pre-trial hearing was originally scheduled for June 30. It was eventually held on October 1 before Judge Carrie Panetta. Klaus argued that Goh was not mentally competent to stand trial, and so Panetta ordered that the hearing be adjourned until November 16 so that a competency evaluation could be conducted. Goh used the services of a Korean interpreter during the hearing, and briefly disrupted the proceedings with an outburst when Klaus began speaking about Goh's mental competence. The court appointed two psychiatrists to evaluate Goh. The hearing resumed on November 19 to discuss the report of the first psychiatrist, which was completed on schedule. According to Klaus' statements, that report concluded that Goh had had paranoid schizophrenia for up to a decade and a half, and that he lacked the ability to cooperate with his public defender due to his incomprehension of the criminal justice system. The report of the second psychiatrist was not yet complete by that time, so proceedings were again suspended until January 7, 2013. Goh refused medication while in jail.

The second psychiatrist's report presented at the January 7, 2013 hearing also concluded that Goh had had paranoid schizophrenia. On that basis, Panetta ruled that Goh was unfit to stand trial, and ordered that he be confined to a mental institution for treatment, with further competency reviews to be held every ninety days. An additional hearing was scheduled for January 28, 2013. Alameda County District Attorney Nancy O'Malley has not yet concluded whether she will seek the death penalty for Goh if and when he goes to trial.

The Oikos University shooting occurred on April 2, 2012, when a gunman shot at people inside Oikos University, a Korean Christian college in Oakland, California, United States, killing 7 people. One L. Goh, a former student at the school, was taken into custody and identified as the suspect in the shooting. Along with the California State University, Fullerton massacre, this was the fourth-deadliest university shooting in United States history, after the Virginia Tech massacre, the University of Texas Clock Tower shooting, and the Umpqua Community College shooting, and the ninth-deadliest U.S. school massacre overall. It is the deadliest mass killing in the city's history.

Goh later moved from Virginia to the San Francisco Bay Area, where he took up residence in Castro Valley and Oakland. His mother Oak-Chul Kim also lived in Oakland, while his brother Su-Wan Ko, a non-commissioned officer in the United States Army, and another brother Su-Kwon remained in Virginia. On March 8, 2011, Su-Wan was killed in an automobile accident in Virginia while on assignment for the George C. Marshall Center. Later that year, his mother returned to Seoul, South Korea, where she died as well. While a student at Oikos University, Goh had disciplinary problems, and was asked to leave the school a few months prior to the shooting.

One L. Goh (born Su Nam Ko; also known as One Goh Ko or One Ko Goh), a 43-year-old former student at Oikos University, was identified as the shooter. He was residing in Oakland at the time of the attack. A native of South Korea, he followed his parents and two older brothers to the United States at a young age and later was naturalized as a U.S. citizen. When Goh arrived to the United States, he first resided in Springfield, a community in Fairfax County, Virginia, outside of Washington, D.C., and then moved to Hayes, in rural Southeast Virginia, where he had minor traffic citations and debts. In February 2002, he legally changed his name to One Goh because he felt his birth name sounded "like a girl's name."
