An Ohio man opened fire at close range on an unsuspecting deputy during a wellness check — missing her by a hair, dramatic video shows.

The footage, released Tuesday by the Warren County Sheriff’s Office, shows Deputy Sara Vaught outside a home in Mason, where cops responded on Feb. 15 after a man called 911 to say his brother had taken something and just wanted to go to sleep, WXIX reported.

Video shows Vaught knocking on the door before saying “here he is” as a suspect later identified by police as 56-year-old Lance Runion sticks a gun outside the door and fires multiple times mere feet from the deputy.

Vaught briefly drops to one knee while returning fire, striking Runion several times. Several other deputies then order Runion to show his hands, the footage shows.

“I’m good, I’m good, I think,” a breathless Vaught tells her partners. “I think I’m good.”

Vaught was not hurt during the exchange of gunfire, deputies said.

Runion, who was in critical but stable condition after being shot several times, was later charged with attempted murder and felonious assault in the incident. He remains hospitalized, WXIX reported early Thursday.

Runion’s brother, meanwhile, had told deputies the man had guns in the house at the time, but didn’t believe he intended to use them, WKRC reported.

Vaught, a Warren County deputy since 2014, is currently on administrative leave as an investigation into the shooting is ongoing, department officials said.
