(NewsNation) — A witness living across from Northside Hospital Medical Midtown described a scene of chaos as a shooter was on the loose in the busy neighborhood.

“Police came and told us to stay indoors because there was an active shooter around us,” Annie Eavenson told NewsNation.

She described the building as including specialized doctor’s offices along with an urgent care center. From her window, she could see medical staff huddled together in offices. Eavenson didn’t hear the shots, although she said there is a lot of construction noise and she may not have recognized them as gunshots.

Eavenson said the sirens seemed to go on for hours as police responded.

“Just a lot of armed soldiers, is what they honestly looked like,” Eavenson said.

Eavenson told NewsNation another hospital had ambulances on scene quickly and she saw some people being brought out on stretchers.

“It’s definitely very scary,” she said. “It’s a very active area, it’s in the heart of midtown.”

The shooting occurred at lunchtime, when Eavenson said the streets are full of pedestrians. The suspect was captured Wednesday evening.
