US College Shooting: First Picture Of Suspect

Police have released a picture of the sole suspect in a shooting at a US college that left seven people dead.

Oakland police chief Howard Jordan said 43-year-old One Goh, who was expelled from Oikos University in California for "anger management" issues, had been co-operative since his arrest after Monday's attack.

But he described the Korean-American as "not particularly remorseful".

Victims had been shot "systematically and randomly" after the shooter learned the female administrator he was looking for was not there, Mr Jordan said.

Goh , believed to be a resident of Oakland, about 10 miles outside of San Francisco, was detained at a shopping centre a short drive from the Christian college, which has close links to the Korean community.

He is expected to be charged later. Officers believe he acted alone.

Mr Jordan said: "We've learned that the suspect was upset with the administration at the school.

"He was also upset that students in the past, when he attended the school, mistreated him, disrespected him, and things of that nature.

"He was having, we believe, some behavioural problems at the school and was asked to leave several months ago."

He described the "very chaotic, calculated and determined" gunman as someone "who came there with a very specific intent to kill people, and that's what his motive was and that's what he carried out".

It is being reported that the suspect had struggled to cope with the deaths of both his mother and brother in 2011.

Goh reportedly spent around a year working with his father, Young Ko, who is in his 70s, at a Korean market after moving to Oakland from Virginia a few years ago.

Residents at the housing complex where Mr Ko lives said he was a humble, hard-working man.

With Goh unemployed after failing to hold down a jobs at the same Korean market as his father and then as a delivery driver, Mr Ko encouraged his son to enrol on the nursing course.

Six of Goh's seven victims, which included six women and a man, have been named by the Alameda County coroner's office as Judith Seymore, 53, Lydia Sim, 21, Sonam Chodon, 33, Kim Eunhea, 23, Doris Chibuko, 40 and Tshering Butia, 38.

The coroner said the seventh victim's identity is being withheld until her next of kin had been informed.

Mr Tshering, a Buddhist, worked nights as a caretaker at San Fransisco Airport but was attending nursing school in the morning at the university, according to his landlord.

Ms Sim looked after children at a local church and also attended nursing classes at Oikos.

And Ms Chodon had worked in education administration for Tibet's exiled government in India before moving to the Bay City area.

A statement on the university's website said: "We deeply mourn the tragic loss of our beloved staff and students. Our hearts go out to those who lost innocent lives and their loved ones."

Officers have been searching for the gun used in the attack , which forensic evidence has shown to be a semi-automatic pistol.

Three wounded victims were released from an Oakland hospital on Tuesday.

It was the deadliest shooting spree at a US college since a student at Virginia Tech shot dead 32 people in 2007 before turning the gun on himself.
