At least seven people were killed Monday when a gunman opened fire at a Christian university in Oakland, Calif.
Law enforcement officials said that the manhunt ended when officers found a suspect at a nearby shopping centre an hour later.
Police spokesperson Cynthia Perkins confirmed the death toll. Three more people were injured at the school, called Oikos University.
The suspect has been identified as 43-year-old One Goh, a former student at the university, said Oakland Police Chief Howard Jordan.
News footage from the scene showed a massive police presence and a chaotic sequence of events as officers swept into the university in search of the shooter.
Other footage depicted bloodied victims being taken outside on stretchers.
Police have not disclosed a motive for the shooting, and they believe the gunman acted alone.
"It's a very fluid situation," Watson told AP.
Witness accounts of what occurred inside the school when the gunfire erupted mid-morning vary.
Witness Angie Johnson, 52, told the AP that the shooter was in a nursing class. She said he began his rampage by shooting a fellow student in the chest at point-blank range. He later sprayed the classroom with gunfire, Johnson said.
At a local hospital, another witness said that the shooting occurred in a nursing class, and that the gunman had been absent for months.
But on Monday, he entered the class and ordered students to stand against a wall.
And when he flashed his gun, students tried to flee and he opened fire, witness Dawinder Kaur told family members.
"She told me that a guy went crazy and she got shot," brother Paul Singh told the Oakland Tribune.
"She was running. She was crying; she was bleeding, it was wrong."
Oikos University, according to its website, has classes in music, nursing, theology and Asian medicine. The classes are available in English and Korean, and the school has less than 100 students.
According to Jim Jong, a pastor at Oikos University, about 30 shots were fired, the Oakland Tribune reported.
"I stayed in my office," he said.
Jong founded the university about 10 years ago.
