(CBS/AP) OAKLAND, Calif. - The nursing program director at the California Christian college where a gunman went on a shooting rampage said Wednesday she thinks she was the suspect's intended target.
Ellen Cervellon said suspect One Goh dropped out of the nursing program at Oikos University last fall, but came back to ask her for a full refund on his tuition.
"In talking to several of the students and faculty who were there, I think he was looking for me. I have that weight on my shoulders and I don't know what to do with it," she told The Associated Press, her voice quivering with emotion.
"Every single one of those students were going to be an excellent, excellent nurse. They're in my heart and they always will be," she said.
Cervellon said she was not on campus that morning because she was doing her other job, teaching nursing to students at California State University, East Bay.
Oakland Police Chief Howard Jordan told The Associated Press Wednesday that investigators believe Cervellon is the person that suspect Goh sought.
Cervellon said Goh also told her that he felt the other students were picking on him. She said he became angry when she said the school could not refund all of his money.
Jordan had told reporters Tuesday Goh was angry after being expelled from the school, but Cervellon said he was never expelled and decided to leave on his own.
"He was never forced out, he showed no behavioral programs, and he was never asked to leave the program," she said. "He decided on his own to leave the program."
Police have said Goh was seeking a female administrator when he went to the Oakland campus Monday morning. When he was told she wasn't there, they say, he began shooting in classrooms.
Six students and a receptionist were killed and three others were wounded when the gunman went on the shooting rampage Monday morning at the university, an Oakland school founded to help Korean immigrants adjust to life in America and launch new careers.
"Only God knows the meaning of the suffering we endure," Dr. Woo Nam Soo, the university's vice president, said in Korean during the church service. "In this unbearable tragedy and suffering, only God can create something good out of it."
Shortly after the deadly shooting spree, police arrested Goh, 43, at a supermarket a few miles from campus.
