OAKLAND (CBS-SF) -- Accused mass killer One Goh told police shortly after he allegedly killed seven people in a shooting rampage at an Oakland university in 2012 that he felt like a laughingstock at the school, according to a video played at his competency hearing.
In an interview with Oakland police about 11 hours after the April 2, 2012 shooting at Oikos University, a Christian vocational school at 7850 Edgewater Drive, Goh said he thought, "Everyone was laughing at me, like a laughing stock."
Goh, now 47, said he thought one of the students "was kind of mocking me" and made him feel like he was "some kind of pervert who thinks about sex all the time."
He said on the video that he had been second in his class but one of the reasons he left Oikos is that he thought there was cheating at the school.
Prosecutors previously said Goh appears to have wanted a refund of his tuition and may have been targeting an administrator who was not present on the day of the shooting.
Goh surrendered to Alameda police at a Safeway store about an hour after the shooting, after he told a security guard that he had shot several people in Oakland.
He is charged with seven counts of murder, three counts of premeditated attempted murder and the special circumstance allegations of committing a murder during a kidnapping and committing multiple murders.
The video of his interview with Oakland police was played as part of an ongoing hearing, which is expected to conclude next week, that will determine if he's mentally competent to stand trial.
Criminal proceedings against Goh were suspended on Oct. 1, 2012, after his lawyers questioned his mental competency to stand trial. On Jan. 7, 2013, a judge ruled that he was incompetent, citing reports by two psychiatrists who examined him.
He has been treated at Napa State Hospital for more than two and a half years and most doctors who've examined him have continued to say that he is incapable of understanding the proceedings against him and assisting in his defense.
But a report by Todd Schirmer, a Napa State Hospital forensic psychologist, in July found Goh competent to stand trial, so a judge recently ordered that Goh face a hearing on his competency.
Prosecutors and defense attorneys agreed at the beginning of Goh's competency hearing last week that Goh wants the death penalty, but they disagreed about whether he reasonably feels guilty for his crime and wants his punishment or if he suffers from persistent delusions that prevent him from understanding the criminal proceedings against him.
If Alameda County Superior Court Judge Gloria Rhynes finds Goh to be competent he will stand trial on the charges against him and could face the death penalty.
But if she finds him to be mentally incompetent he will be permanently placed at a psychiatric treatment facility such as Napa State Hospital.
