Roseburg: Its Story Doesn't End with Yesterday's Shooting

ORIGINAL POST, THURSDAY, OCTOBER 1, 11:52 AM:

Information's scant at the moment, but the news that's out there is bad: A mass shooting at Roseburg's Umpqua Community College had claimed multiple victims. The Oregonian has an updating story—

Scanner reports indicated the suspect is down. Multiple ambulances are on scene. Early reports indicate at least 15 people are dead. (Via.)

As does CNN—

Preliminary information indicates 10 people were killed and more than 20 others injured in a shooting at Oregon's Umpqua Community College on Thursday, said Oregon State Police spokesman Bill Fugate.

The reports suggest the shooter has been detained, he said. (Via.)

And the New York Times

The first 911 calls reported shooting at Umpqua Community College at 10:38 a.m., and several law enforcement agencies responded. Officials said there were multiple casualties, but they were not sure of a number. (Via.)

Roseburg's News Review is updating with news and a few images, noting the city's Mercy Medical Center is "under extreme stress dealing with victims from the shooting." As of a few minutes ago, they posted that

Jared Norman, a nursing student at UCC, said he heard shots and then everyone was running. He is locked down in the cafeteria with 50 other students right now. They’ve heard there is a shooting, but they don’t know what’s going on. And they’re scared. (Via.)

UPDATE, 1:05 PM:

More info is trickling in: The Oregonian reports that "The FBI is sending agents and specialty personnel from its offices in Medford, Eugene, Salem and Portland to assist with the active shooter investigation" and that students are being bused to the Douglas County Fairgrounds.

Still no confirmation on the number of people wounded or deceased.

Meanwhile, the New York Times reports President Obama has been briefed on the shooting, and that authorities have stated the shooter is "no longer at large," though it's unclear if "that meant he was alive or dead."

"The shooting at Roseburg was one of over 40 school shootings this year," the Times writes. "There had not been a major mass casualty incident at a school this year—until Thursday." EH

UPDATE, 1:20 PM:

According to sources speaking to Mercury News Reporter and former Roseburg resident Shelby R. King, a police sergeant on the scene has confirmed the suspected shooter is dead—but at this point, can't go on the record saying how. This is backed up by a press release from the Oregon State Police: "It is believed there is only one shooter who is no longer a threat. There is no current threat to the community." EH

UPDATE, 1:42 PM:

Attorney General Ellen Rosenblum confirms to the Mercury's Shelby R. King that there are 13 dead and 20 wounded. EH

The shooter exchanged gunfire with authorities from inside Snyder Hall where an English class was in session, according to a student who spoke with the News Review, Roseburg's paper. The student reported seeing the teacher shot in the head. The shooter was armed with a "long gun," according to dispatch recordings between Roseburg Police and dispatchers.

Students and staff are being bused to the Douglas County Fairgrounds. Friends and family worried about their loved ones are being asked to go there, according to Oregon State Police.

A former UCC president reported that there was only one security guard on campus at the time of the shooting, and that security guard is not armed. SRK
