Tulsa gunman left note blaming surgery pain for killing his doctor and three others

Officials also released the names of the two doctors, receptionist and patient killed in Wednesday’s shooting

Officials have identified the man suspected of shooting and killing four people at a medical clinic in Oklahoma.

Tulsa Police Department police chief Wendell Franklin said that Michael Louis, who they believe also died of self-inflicted wounds, was a patient at Tulsa medical clinic and was admitted to the facility on 19 May for back surgery.

He reportedly called several times afterward complaining about pain and sought “additional treatment”.

“On May 31, Dr [Preston] Phillips saw Mr Louis again for additional treatment. Yesterday, June 1, Mr Louis called Dr Phillips’ office again and wanting additional assistance,” the police chief said in a statement.

“Now we know through the help of our ATF and our gun tracing that on June 1 he purchased a semi-automatic rifle from a local gun store,” Chief Franklin said.

That firearm was an AR-15 rifle, he added.

Prior to that, the suspected gunman had purchased a semi-automatic handgun on 29 May from a local pawn shop, the police chief said.

All firearms, according to Chief Franklin, were purchased legally.

On Wednesday, officers responded to reports of a man with a rifle at St Francis Hospital’s Natalie Building, which then turned into an “active shooter situation”. The building houses an outpatient surgery centre and a breast health centre.

The Tulsa Police Department said five people were dead in total, including the shooter.

Authorities revealed the identities of the four people killed during Wednesday’s mass shooting, which included three emloyees of Saint Francis Healthcare system and one patient.

The victims were identified as Dr Preston Phillips, Dr Stephanie Husen, Amanda Glenn and William Love.

Ms Glenn was identified by police as a receptionist at the facility, while Mr Love was a patient.

”They stood in the way, and Louis gunned them down,” the police chief said during a press conference.

Authorities went on to reveal during Thursday’s press conference that they’d found a letter on the suspect, which they said “made it clear he came in with the intent to kill Dr Phillips” and added that the shooter also said he’d kill “anyone who got in his way”.

“This is what he planned to do,” said Chief Franklin. “That letter told us the story.”

Chief Franklin later went on to praise his staff for their fast response to Wednesday’s shooting.

“I cannot begin to thank the men and women of the TPD for the immediate response they had to the incident yesterday,” he said. “Our training led us to take immediate action without hesitation, that’s exactly what our officers do.”

Louis’ wife and Chief Franklin confirmed that the gunman had complained about his ongoing back pain issues after being discharged from hospital on 24 May and blamed Dr Phillips following his surgery, according to Tulsa World.

The shooting in Tulsa that left four people and the shooter dead came just eight days after the Uvalde massacre, where 19 children and two teachers were brutally murdered by a teenage gunman, and two weeks after a self-proclaimed white supremacist and racist shot dead 10 Black people in a grocery store in Buffalo, New York.
