NAPLES, Fla. - WINK News is learning what it was like to be on the Johns Hopkins Hospital campus at the time of Thursdays shooting.

A woman from Naples was working in the building next door when a gunman shot a surgeon.

Stephanie Miller said minutes after the gunman fired his fun, the entire hospital campus was notified. She was moved into a room in the basement with co-workers - listening to what was happening on scanners nearby.

"The supervisor came in my room and said 'you need to shut your door. There's been shots fired'. My jaw was dropping. I was like are you serious? I know this happens outside. It's a very violent city. It's not sweet little Naples, Florida where you can drive around with your car doors unlocked. People have been shot on the hospital campus before, but never inside, so I was shocked. I was in total shock."

Miller told us the hospital was on lock down for about two hours. She also said the shooters mother was a patient at the hospital. After shooting a doctor, the man shot his mom, then himself.
