Shootings at Oikos University A public defender representing defendant One Goh said a psychiatrist has determined that Goh suffers from paranoid schizophrenia that dates back several years. Alameda County Assistant Public Defender David Klaus has said the condition causes Goh to distrust people, including those trying to help him. Klaus has said he and his co-counsel have had trouble talking with Goh because of his mental state. Goh is charged with seven counts of murder and three counts of attempted murder in the April 2 attack at Oikos University in Oakland. He has pleaded not guilty. Authorities have said Goh, a former Oikos student, planned the killing spree at the school that caters to Korean immigrants after becoming angry with school officials over a tuition dispute. He previously decided to drop out of the school's nursing program. A judge ordered Goh to return to court Jan. 28.
