Oklahoma gunman who killed four, targeted surgeon

TULSA, Okla., June 2 (Reuters) - A gunman, who fatally shot five people including himself at a Tulsa, Oklahoma, medical building after buying an assault-style rifle the same day, had gone to there to kill a doctor who he blamed for back pain he felt after surgery, authorities said on Thursday.   

The suspect, identified as Michael Lewis, entered a building on the St. Francis Health System campus with an AR-15-style weapon and opened fire at anyone he encountered, killing two doctors and two other people, Tulsa Police Chief Wendell Franklin said during a news briefing. 

 
The suspect “came in with the intent to kill Dr. Phillips and anyone who came in his way,” Franklin said. Authorities found a letter on Lewis that made it clear that the attack was targeted.   

Dr. Preston Phillips, 59, the surgeon who treated Lewis, was killed along with Dr. Stephanie Husen, a 48-year-old sports medicine specialist.
