The suspected gunman in a mass shooting at an Oklahoma medical office Wednesday bought an AR-15-style rifle just hours before the massacre, police said.
Five people were killed in the shooting at a medical complex at Saint Francis Hospital in Tulsa, according to the Tulsa Police Department. The alleged shooter died of a self-inflicted gunshot wound, police said.
Among those killed was Dr. Preston Phillips, who had performed back surgery on the alleged gunman last month, Tulsa Police Chief Wendell Franklin said at a news conference Thursday.
A letter recovered on the suspect — identified by police as Michael Louis of Muskogee, Oklahoma — “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.”
The three others killed were Dr. Stephanie Husen, receptionist Amanda Green and patient William Love, Franklin said.
As police continue to investigate the incident — the 233rd mass shooting in the U.S. so far this year, according to the Gun Violence Archive — this is what is known so far.
“This information is fluid and can still change but it is the most accurate information that we have at this point,” Franklin said.
