Oakland shooting: Oikos gunman lined up victims and ‘started shooting,’ police say

Monday's shooting at California's Oikos University left at least seven people dead, and more details are emerging as to the suspect's motive. One Goh, the 43-year-old suspected male shooter and former nursing student at the school, was upset with a female administrator for dismissing him, which led to the shooting spree, Oakland Police Chief Howard Jordan said.

"He just felt a certain urge to inflict pain on them," Jordan said on CNN. "He gave us no exact reason why he did that. He just wanted to get back at the administration for dismissing him earlier in the year."

Goh "entered the building, and he took one of the receptionists, entered the room, was looking for one person in particular and I can't reveal that person's name because that person, we don't want to jeopardize their safety," Jordan continued. "He lined up all the victims and began shooting at them and left for a short period of time, came back, went through other parts of the school just shooting, what we call a shooting rampage throughout the school."

"He lined them up just like I said and started shooting them one by one," Jordan said.

Goh then "casually walked out" and left in one of the victim's vehicles, Jordan told the network. "He came back into the classroom after he left, went to another location, and began shooting again because he realized that there were other students hiding in the adjacent classroom. He began shooting into that classroom again. Then left out the back, not through the same entrance that he came in."

Goh was arrested at a nearby Safeway, police said.

The suspect was not enrolled at the religious university at the time of the shooting, Oikos founder, Pastor Jong Kim, told the Oakland Tribune.

On "Good Morning America," Jordan said Goh had been "mistreated" by other students. According to the Associated Press, Jordan said the suspect was teased by other students over his English skills.

He added: "This was a calculated, cold blooded execution in the classroom that led to these victims, all seven of the ten of them, being deceased at this point."
