Tulsa: Four people were killed, including a gunman, in a shooting on a hospital campus in Tulsa, Oklahoma, police said.
Officers were still working to clean up the St. Francis Hospital campus, the Tulsa Police Department said on Twitter.
Tulsa Police Captain Richard Meulenberg told the ABC that “four people were shot dead.”
“One died after leaving the scene to try to get medical attention, and one of those four will be our suspect.”
“Officers are currently going through all the rooms in the building to see if there are any additional threats,” police said. “We know there are multiple injuries and potentially multiple casualties.”
St Francis Health System closed its campus due to the situation in the Natalie Medical Building. The Natalie Building houses an outpatient surgery center and a breast health center.
Aerial footage of a television helicopter appeared to show the first perpetrators driving someone on a stretcher away from the hospital building.
Dozens of police cars could be seen outside the hospital complex and authorities closed traffic as the investigation progressed.
