The horrific video, which has now been seen thousands of times on social media, shows the exact moment Devyn Holmes was shot on Sunday.

Cassandra Damper, the woman who shot Holmes, has since been charged.

The beginning of the video shows Holmes picking up the gun and looking at it.

It then cuts to another part of the live feed, when a man in the backseat puts the gun back between Holmes and Damper.

Then Damper picks up the gun and points it directly at the camera as Holmes grabs her hand.

'You're making me nervous,' he tells her.

'She ain't got no clip bud,' the man, believed to be Cadillac Coleman, tells Holmes.

'Where you from again?' Holmes asks Damper points the gun at him and says, 'Say something, b***h.'

The gun then goes off and Damper gasps as a bullet hits Holmes in the head, blood pouring into his white T-shirt.

She and Coleman immediately flee the car, leaving Holmes bleeding out in the front passenger seat.

Damper was charged with tampering or fabricating of evidence after she tried to wipe gunshot residue from her hands, according to .

She told police that she didn't know the gun was loaded.

Coleman has not been charged.

Authorities said a grand jury will decided if any additional charges should be filed.
