At least 3 people were killed in a Tulsa, Oklahoma, hospital campus shooting, police say

CNN  — 

At least three people were killed Wednesday in a shooting on a hospital campus in Tulsa, Oklahoma, police said.

The shooter is also dead, police said in a Facebook post.

Authorities responded to a call about a man who was armed with a rifle at the Natalie Medical Building, a physicians’ office building on the St. Francis Hospital campus, according to an earlier Facebook post from the Tulsa Police Department.

“At this point, we can confirm the shooter is dead,” police said in the post, although it was not clear whether the shooting was self-inflicted.

“Officers are currently going through every room in the building checking for additional threats,” the post added.

Police were going through “multiple floors” clearing the building and evacuating victims Wednesday evening, Richard Meulenberg, with police, said Wednesday, adding that there are “hundreds of rooms and hundreds of people within the building.”

“We’re treating this as a catastrophic scene right now,” Meulenberg said.

There has been a reunification site set up for family members and friends at Memorial High School west of LaFortune Park, police added.

President Joe Biden has been briefed on the shooting, a White House official said. The White House is closely monitoring the situation and has reached out to state and local officials to offer support.

The Bureau of Alcohol, Tobacco, Firearms and Explosives is also assisting on scene, the ATF Dallas Field Division said on Twitter.

Debra Proctor was in another building on the hospital campus for a doctor’s appointment when she heard police sirens ringing out.

When she stepped outside, first responders were lined up everywhere, she told CNN. Proctor, who has been a registered nurse for more than four decades, said it was a “shocking” scene.

“Police were everywhere in the parking lot, up and down the surrounding blocks,” Proctor said. “They were still arriving when I was leaving.”

Kalen Davis, a lifelong Tulsa resident, was waiting in traffic around 5 p.m. local time when she saw multiple police cars responding to the scene.

In a video she shared with CNN, authorities can be seen running toward a building with their guns drawn. Two officers are seen taking long guns out of their trunks as more emergency vehicles race to the scene.

“I just knew that it was a shooting situation because I saw police running with rifles,” Davis, 45, told CNN. “That’s when I got emotional.”
