A former nursing student was charged with murder and attempted murder on Wednesday over a shooting rampage that left seven people dead and three others wounded this week at a small, Christian college in California that had expelled him.
The suspect in the shootings at Oakland's Oikos University, 43-year-old One Goh, was scheduled to be arraigned on Wednesday in Alameda County Superior Court.
District Attorney Nancy O'Malley said Goh had been charged with seven counts of murder with "special circumstances," and three counts of attempted murder.
"The enormity and devastation of these crimes is unprecedented in Alameda County," she said.
Goh is accused of opening fire on former classmates at Oikos on Monday in the deadliest outburst of gun violence at a U.S. college since a Virginia Tech University student killed 32 people and wounded 25 others before taking his own life in 2007.
Police said he had been expelled from Oakland's Oikos University for "anger management" issues.
Goh surrendered at a grocery store several miles (km) away a short time after Monday's shooting.
Oakland Police Chief Howard Jordan said on Tuesday that Goh had been cooperative since being taken into custody but was "not particularly remorseful."
Jordan said the accused gunman had gone to the school intent on attacking a school administrator and classmates he felt had treated him unfairly. The administrator he sought was not there at the time, but six students and a secretary were killed.
People who knew Goh said the rampage followed a period of personal tumult for him. His brother, a U.S. Army sergeant, was killed in a car accident last March, and his mother died in South Korea about a year ago. Court records also showed he was involved in a dispute with the owners of an apartment in Virginia who had evicted him and claimed he owed back rent.
The three wounded victims were released from the hospital on Tuesday.
