ROSEBURG, Oregon — The Umpqua Community College shooter has been identified as 26-year-old Chris Harper Mercer, law enforcement sources confirmed to CBS News.
Oregon State Police reported as many as ten dead including the gunman and 20 injured.
Sheriff John Handlen held a news conference on the incident Thursday afternoon.
He told reporters law enforcement received a call around 10:30 a.m. that said a shooter was inside a classroom on campus, and within minutes, police were on the scene.
Officers exchanged gunfire with the shooter who was later killed.
CBS New was told by law enforcement sources four guns, a combination of pistols and a rifle, were found at the scene of the shooting.
Officers swept the campus to look for other threats but finally lifted the lockdown on the Community College campus.
No one is currently allowed onto the campus as the investigation continues.
Students were taken off campus to the state fair grounds where they were reunited with family and friends.
Eighteen-year-old Kortney Moore of Rogue River tells the Roseburg News-Review newspaper that she was in a writing class when a shot came through a window.
She says the gunman entered her classroom, told people to get on the ground and then asked people to stand up and state their religion before opening fire.
Krys Denino, a mother of two and first-year nursing student at the college, was on campus when the shooting started.
She told CBSN by phone that she initially thought what she heard was from a construction project and didn’t realize the sounds were gunshots until she saw a young woman running toward her. She heard another gunshot and then started running to her car.
A photographer for the Roseburg News-Review newspaper said he saw people being loaded into multiple ambulances and taken to the hospital.
CBS News correspondent Ben Tracy reports authorities believe shots were fired both inside Snyder Hall and the nearby science building on the campus of more than 100 acres.
Mercy Medical Center in Roseburg said Thursday night that four people remained hospitalized there but are expected to survive.
Dr. Jones Gray, chief medical officer, said one of the four people are in critical condition, and the others are stable.
PeaceHealth Sacred Heart Medical Center in Springfield said it received three female patients between the ages of 18 and 34 via helicopter. Dr. Hans Notenboom of the emergency department said two of the patients went directly into the operating room.
The hospital later tweeted that two of the victims were in serious condition and one in critical.
Oregon State Police, local agencies including the Roseburg Police, the Sheriff’s Office, FBI, U.S. Marshall’s office, and other agencies are all on the scene.
Roseburg is a small community located in Douglass County.
Approximately 107,000 people call the town home and only 3,000 students.
The school will be closed until Monday.
