From another website. Said the guy threatened the same thing at a Whitesburg clinic yesterday

Dr. Sandlin of Leatherwood Blackey clinic was shot by a patient today after telling the man he was unable to give him pain pills. "If that is how you feel about it, I will just blow your head off" The man said. He walked out to his vehicle and got a gun. He walked back into the clinic and shot the doctor.
Thats sad Pills have screwed some folks up so bad its unbelievable.
