Devyn Holmes, 26, is on life support after the Easter Sunday shooting while hanging with pals in a parking lot of a gas station, news station KHOU reported.
Police said Holmes was in the vehicle early Sunday with Cassandra Damper, 25, and another man when the woman began pointing the gun at the camera.
“You’re making me nervous,” Holmes could be heard saying in an edited video circulating online.
Holmes is seen in the footage attempting to stop the woman from waving the gun around.
“It ain’t got no clip, bud,” another person reportedly responded.
But seconds later, the gun fired and struck the 26-year-old man, according to KHOU. The footage making rounds on social media does not show the moment he was gunned down but does show him slumped over and covered in blood.
Holmes was rushed to Ben Taub Hospital, where he remains in critical condition, police said.
Officers arrested Damper after she allegedly attempted to wipe off the gun residue on her hands. She was booked on charges for tampering or fabricating evidence.
Damper claimed that she was unaware the gun was loaded in an interview with authorities.
The other man involved in the shooting video was not charged.
Police said more charges could be forthcoming.
