A witness has described the moment a suspected gunman opened fire inside a Nevada medical office, killing one person and wounding two others before turning the weapon on himself.

The wounded victims were in surgery, and one of them is a doctor, the Nevada Department of Public Safety said late Tuesday. Both are in critical condition, police said.

Vicki Green, who had been scheduled to see a doctor, told NBC affiliate KRNV that the gunman seemed “calm but agitated” when he stood beside her at the nurses’ station shortly before the shooting in the Center for Advanced Medicine and Neurology on the Renown Medical Center complex.

“I could have grabbed the gun I was that close to him, I could have grabbed him,” she told the station. “It’s surreal, I felt like I was seeing myself in a movie. This kind of thing happens on TV. It doesn’t happen here.”

She added that the shooter started swinging the gun, which she thought might have been a shotgun or a rifle and telling people, “you need to get out,” and people began to flee for their lives.

The gunman killed himself after firing off several rounds in the Center for Advanced Medicine and Neurology on the Renown Medical Center complex at about 2 p.m. local time on Tuesday, police said.

“We have two people confirmed deceased in the building, two others injured,” Reno Police Department’s Deputy Chief Tom Robinson told reporters.

Department of Public Safety spokeswoman Gail Powell told The Associated Press that the wounded doctor is a woman.

Police do not have a solid identification on the suspected gunman but do not think the shooting was random, Robinson said in an evening news briefing.

The motive for the attack remained unclear.

The medical center was put on lockdown amid the chaos of the shooting scene as police, including SWAT team vehicles, surrounded the sprawling medical complex and closed off a three-block area near downtown Reno.

Gov. Brian Sandoval posted on Twitter that he and his staff were monitoring the situation and his thoughts and prayers were with those affected by the tragedy.

The Renown Medical Center tweeted that they will reopen on Wednesday.
