In the video, which was shared on Facebook and Instagram, Holmes is seen wearing a white shirt and talking to the woman and another man who is also in the vehicle. Friends of the victim confirmed to KHOU that Holmes is seen in the video, wearing a white shirt.
Surveillance footage shows the doors of the auto flying open and two people jumping out following the incident.
Holmes could reportedly be heard in the video telling the woman holding a handgun that she was making him nervous. The man who is sitting in the back seat places a gun on the car's armrest, before Damper pulls out another gun and waves it in front of the phone camera.
A second later, the gun fired.
'She ain't got no clip bud, ' the other man tells him.
The 26-year-old man slumped over on his side and blood began pouring out of his head.
The footage has been deleted and one person has been charged with tampering with evidence.
Damper reportedly told police she believed the gun was unloaded.
The unidentified male passenger in the auto has not been charged.
Damper allegedly tried to remove gun residue from her hands after the shooting, which police are preliminarily investigating as accidental.
According to the New York Post, police said more charges could be forthcoming.
