Investigators found 13 weapons connected to the man who killed nine people on Thursday at Oregon's Umpqua Community College, the U.S. Bureau of Alcohol, Firearms, Tobacco and Explosives said on Friday at a news conference.
Six weapons were found at the college, where the shooter died Thursday after a gun battle with police, the Bureau’s Celinez Nunez said, according to CNN. Seven weapons were found at his residence.
Nunez said all weapons were legally obtained through a federal firearms dealer during the last three years by the shooter or family members.
A flak jacket was found next to a rifle at the school with five magazines of ammunition, she added, and additional ammunition was found at the residence.
Authorities are still not providing a motive for America's latest mass killing, which also left nine people wounded. They also haven't named any of the victims or the shooter.
The man went to the college in rural south Oregon with handguns and a long rifle Thursday morning and shot people in two buildings, authorities said.
Stacy Boylan, the father of shooting victim Anastasia Boylan, said she told him the gunman singled out Christians.
She said the gunman entered her classroom firing, told the professor teaching the class, "I've been waiting to do this for years," and shot him point blank, Stacy Boylan said.
The gunman, while reloading his handgun, ordered the students to stand up and asked if they were Christians, Boylan told her family, according to CNN.
"And they would stand up, and he said, 'Good, because you're a Christian, you're going to see God in just about one second,' " Stacy Boylan told CNN, relaying his daughter's account.
"And then he shot and killed them."
Multiple law enforcement officials familiar with the investigation have identified the gunman as Chris Harper Mercer, 26.
It remains unclear if Mercer was a student at the college. Rita Cavin, interim president of the school, said Mercer was not believed to be a current student, but some students said they took courses with him.
