Officer Kelly Beemer was released from jail Thursday night after posting bond. She is charged with one count of discharging a firearm in a municipality.
Police said Beemer, a 27-year-old patrol officer, was at a Dallas bar Wednesday night while off-duty and was too drunk to drive. Two on-duty officers came to pick her up.
Investigators said Beemer got belligerent as officers were driving her to her east Dallas home.
On Thursday, Dallas police released dashcam footage of the incident.
"This is what you've wanted," she can be heard saying on a dashboard camera video.
"To take you home?" one of the two other officers asks.
"To drive me out of my mind to where I have no [expletive] control, no control whatsoever. Isn't this what you wanted?" she can be heard saying.
Police said Beemer thought she was being taken to jail. She pulled out her police-issued handgun and fired a single shot in the floorboard near the intersection of Gaston Avenue and Abrams Road, police said.
An officer can be heard on the dashcam footage yelling, "Kelly, drop the gun! Drop the gun! Drop it! Drop it!"
Police Chief David Brown said he is extremely disappointed by her actions, calling them "reckless” and “unacceptable."
No one was hurt, but police said Beemer's actions have the potential to shake public confidence in the department.
“Officer Beemer's conduct is a disgrace to herself and the people trying to help her,” First Assistant Chief Charles Cato said.
Police said they released the footage from the dashboard camera so the department cannot be accused of trying to cover the incident up.
Beemer has been placed on administrative leave pending the outcome of an internal investigation. The other two officers involved have been put on restricted duty.
