Oklahoma gunman who killed four targeted surgeon who treated him

The suspect entered a building on Tulsa's St Francis Health System campus on Wednesday with a semi-automatic weapon he had bought earlier that day and opened fire at anyone he encountered, Tulsa Police Chief Wendell Franklin said during a news briefing. Two doctors and two other people were killed.

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