Tulsa mass shooter allegedly gunned down his doctor after asking for help with PAIN

A patient gunned down his surgeon and three other people in a mass shooting at a Tulsa, Oklahoma, medical building on Wednesday after blaming the doctor for his PAIN, according to police.

On May 19, the suspected gunman underwent back surgery. Dr. Preston Phillips one of the four people killed in the shooting at the Natalie Building, a five-story medical complex at Saint Francis Hospital was the suspect's doctor in that surgery, Tulsa Police Chief Wendell Franklin said at a news conference Thursday.

A letter recovered on the suspect, Michael Louis, made it clear "that he came with the intent to kill Dr. Phillips and anyone who got in his way," Franklin said. "He blamed Dr. Phillips for the ongoing pain following the surgery."

Louis bought an AR-style semi-automatic rifle just hours before the shooting, Franklin said. He bought a 40-caliber pistol from a pawn shop on May 29, police said. Both appeared to be legally purchased, police said.

The three others killed were Dr. Stephanie Husen, office employee Amanda Glenn and patient William Love, Franklin said.

Louis' body was found in the lobby area of Phillips' office from an apparent self-inflicted gunshot wound, police said.

Authorities said Louis had been released from the hospital on May 24, five days after his surgery. After his release, Louis called Phillips several times over several days complaining of PAIN and wanting additional treatment, the chief said.

On Tuesday, Phillips saw the suspect again for additional treatment, the chief said. On Wednesday, the suspect called the doctor complaining of back pain and wanting additional help, the chief said.
