The gunman who killed nine people in a shooting rampage at a college in the US state Oregon killed himself as police arrived, officials have said.
At a news conference in Roseburg, they revealed that Chris Harper Mercer, 26, was enrolled in the class where the shooting took place, BBC reports.
They said that 14 weapons were later found at his home and the college.
Police earlier released the names of the victims, who ranged in age from 18 to 67. The oldest was a teacher.
US President Barack Obama on Friday expressed his anger at gun violence, calling on the public to press their politicians to support reform.
“The medical examiner has determined the cause of death of the shooter to be suicide,” Douglas County Sheriff John Hanlin told reporters on Saturday.
On Thursday, Mercer brought six guns to Umpqua Community College in Roseburg and opened fire. He then killed himself after a gun battle with police officers who arrived at the college.
The gunman also reportedly left a “manifesto”–a typed statement that was several pages long. Officials did not reveal the content of the note.
It is unclear why Chris Harper Mercer carried out the killings. Two victims have said religion was an issue, as the gunman asked his victims to state their religion and shot dead the Christians.
