(AP Photo/Noah Berger) (Newser) – One L. Goh arrived at the Oikos University yesterday hoping to kill a specific female administrator, only to discover that she wasn't there, police said today. "We've learned that the suspect was upset with the administration," Oakland's police chief told Good Morning America. "He was also upset that students in the past … mistreated him, disrespected him, and things of that nature. He was having, we believe, some behavioral problems at the school and was asked to leave." In his quest for the administrator, Goh "went through the entire building, systematically and randomly shooting people," the police chief said, according to the AP. Police say Goh has been willingly talking with them about the shooting. "He's been very cooperative," the chief tells the San Francisco Chronicle. "He (has) not been particularly remorseful, but very cooperative."
