There have so far been at least 233 mass shootings in 2022, according to the nonprofit organization Gun Violence Archive — including today's shooting in Tulsa.
June 1 was the 152nd day of the year. This means there have been more mass shootings this year than there have been days in 2022.
CNN and the GVA define a mass shooting as a shooting that injured or killed four or more people, not including the shooter.

Tulsa Police Department Capt. Richard Meulenberg told CNN's Laura Coates that officials are not releasing the name of the shooter or any information pertaining to the individual due to the ongoing investigation at the scene, as well as investigations underway at other locations.
“So we're still working with other agencies and other jurisdictions as this is related to a much bigger issue with this shooter,” he said.
Meulenberg said police do not believe anyone else is in danger, but they are looking at locations outside of the facility. He added that the police do not think the shooter was targeting the entire five-floor facility, but instead that he targeted the second floor and “went to this floor with purpose."
After law enforcement breached the door, they found the gunman dead with both “a rifle and pistol on his person,” the captain said.

Tulsa Police Department Capt. Richard Meulenberg told CNN's Laura Coates multiple people were wounded in the shooting on the St. Francis Hospital campus.
“We have some other wounded – less than 10,” Meulenberg said.
Those injured are not suffering life-threatening injuries, according to Meulenberg.
He said investigators are trying to determine if those injured were wounded by gunfire or from the chaos of escaping the scene.
“We're still figuring it out as people scattered and were carted off very quickly to this hospital and other hospitals with injuries,” Meulenberg said.

Read the full statement below:
"What happened today in Tulsa is a senseless act of violence and hatred. Sarah and I are praying for the families of those who lost their lives and for those who were injured. I am grateful for the quick and brave actions of the Tulsa Police Department and other first responders who did their best to contain a terrible situation. I have offered Mayor G.T. Bynum any state resources that may be needed, and I ask all Oklahomans to come together in support of the Saint Francis Health System community and to grieve with those whose lives have been forever changed."

Tulsa Deputy Police Chief Eric Dalgleish told reporters Wednesday the gunman in the shooting on the St. Francis Hospital campus used two firearms during the shooting.
Dalgleish says the gunman had a long gun, or rifle, and one handgun. The deputy chief said it is believed the gunman fired both weapons during the shooting.

Tulsa Police officers responded to the scene of an active shooting on the St. Francis Hospital campus within minutes of the first call, arriving while the shooting was ongoing, Deputy Chief Eric Dalgleish said in a news conference Wednesday night.
“The officers that did arrive were hearing shots in the building, and that’s what directed them to the second floor,” he said.
The shooting took place in the Natalie Medical Building on the St. Francis campus.
“This campus is sacred ground for our community,” said Mayor G.T. Bynum, who praised the response of law enforcement. “Men and women of the Tulsa Police Department did not hesitate."
Police say four victims were shot to death. It was not immediately clear whether the victims were medical staffers, patients or both. Dalgleish described the shooting scene as an orthopedic center.
Police said they were still working to identify the shooter and his motive. The shooter died from what is believed to be a self-inflicted gunshot wound, and no police officers were injured, Dalgleish said.
“There will obviously be many questions, and there will be a very bumpy road, I think, ahead of us,” said Dr. Cliff Robertson, St. Francis Health System CEO, adding that the shooting was a “senseless, horrible, incomprehensible act.”

Kalen Davis, 45, a life-long resident of Tulsa, told CNN she was waiting in traffic at around 5 p.m. CT when she saw multiple police cars responding to an incident at 65th Street and Yale Avenue.
In the video she shared with CNN, police are seen running toward a building with their guns drawn. Two other officers are seen taking long guns out 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 told CNN. "That's when I got emotional."
