Chief Medical Doctor of the Emergency Department at Vally Hospital Medical Center and longtime Chief Ultimate Fighting Championship (UFC) Doctor Jeffrey Davis admitted on camera that a 'mass casualty incident disaster drill' was activated after the massacre in which 59 people were killed, according to official reports.

The famous doctor said that he was at home Sunday night when got a call (around 10 p.m. local time) from one of his office directors who notified the doctor that there was 'possibly' a mass shooting with multiple victims and that the hospital was going to activate a 'mass casualty incident' or 'disaster drill.'

"Sunday evening I was at home. Probably like everyone getting ready for nighttime […] I was notified by one of my office directors that there was a shooting, possibly a mass shooting, with multiple victims and that we were going to initiate what is called a 'mass casualty incident' or 'disaster drill'," the doctor explained. "Initially I didn't know what she was talking about, many people didn't, and she said 'turn on your T.V'. At that time I did and I started to witness what everyone else in the world was witnessing."
