Police released the shocking dashcam footage Thursday afternoon, which consisted of three videos that were edited to show Dickson holding and firing a gun.

The video first shows Grafton slowing down his vehicle before he spots Dickson running along a sidewalk in front of Jenks East Elementary School.

At first glance, it's unclear what Dickson is holding in her right hand until the video is slowed down and a red circle shows the gun.

Officers can be heard telling dispatchers that multiple shots are fired.

Dickson then points her gun toward the police vehicle as the car moves toward her.

The woman appeared to be yelling before she's struck by the police cruiser. She is then seen falling and going beneath the hood of the car.

Grafton, who has been with the department for six years, remains on paid leave while an investigation is carried out.

Tulsa Police Officer Leland Ashley told Tulsa World that Officer Kayla Johnson and Detective Ronnie Leatherman fired their guns during the exchange.

Dickson was wanted by police over four gun-related incidents in Tulsa during the past week, including shooting a man in the head.

She eventually jumped out of the truck and started firing at the officers when Grafton hit her with his vehicle.

Authorities said they had desperately tried to stop Dickson because of the threat she was posing.

'She had every opportunity to stop and turn herself in,' Ashley told Tulsa World.

Police said no one was struck by any bullets and Dickson died when she hit her head on the ground.

The female driver of the truck was questioned and released.

Dickson was accused of shooting a man in the head on Thursday night and causing him to crash his car. The man is still in a critical condition in hospital.

She had also reportedly shot a woman in the arm at a Walgreens store and fired her gun during a robbery at a Best Buy.
