LAS VEGAS (KLAS) — A man is facing several charges after police say he shot and killed a man, stole a vehicle to leave the scene, and was later found “waving a gun around” while stripping in front of a family’s home, according to an arrest report.
The Homicide
On Sept. 2, at around 7:40 p.m., police were called to the 6400 block of Plumcrest Road after several calls were made to 911 after a man was shot.
The report stated arriving officers found the victim, identified as Glen Cooper, 48, in the driveway of a home with a gunshot wound in his chest. He was taken to a local hospital, where he later succumbed to his injury and was pronounced dead.
The owners of the home told police they witnessed the shooting. According to the report, a witness told police that an ex-boyfriend of hers, Parnell Gaines, 46, shot Cooper after an argument took place in front of the home.
The report stated the witness told police she dated Gaines for two to three years, but their relationship ended in April 2023 because Gaines was physically abusive to her and her aunt.
She told police both she and her aunt got protection orders against Gaines, which Gaines “routinely ignored and violated.”
She told police that Gaines would show up at her home and work and “try to rekindle” their relationship.

According to the report, the witness was friends with Cooper and invited him to stay with her when he lost his home.
The witness told police Gaines showed up at a church where she was doing community service and stayed there until she finished. The two drove to the witness’ home, the report stated.
While the witness went inside to change her clothes, she asked Cooper if he would like to join them on a run to the store. He agreed.
Outside, the witness’ aunt approached Gaines where he was sitting in the passenger seat of the car and told him he was not allowed to be at the house because of the protection orders.
According to the report, Gaines called the aunt several derogatory terms for women, at which point, Cooper stepped in, telling Gaines not to talk to her “so disrespectfully.” The report stated that Gaines called Cooper a name then Cooper slapped him.
The report stated that Gaines then pulled out a gun and shot Cooper in the chest. The bullet ended up going through the wall of the home and into the bedroom of the witness’ children.
According to the report, Gaines then threatened to shoot the witness if she did not let him take her vehicle, which he drove away before police arrived. His brother later returned the vehicle to the home while police were on the scene.
The History
According to the arrest report, Gaines was arrested for several domestic violence incidents against the witness and was a person of interest in two additional domestic violence incidents against her aunt.
A records check showed that Gaines was a five-time felon in Nevada for the following offenses:
- Robbery, convicted in 1998

The Arrest

The woman told police that she and her pre-teen daughter got home from the store when a man, later identified as Gaines, approached them and attempted to grab her twice. She was able to pull away and ran into her home with her daughter.
According to the report, Gaines entered her front yard and began to take off his clothes. He tried to enter her home, kicked her front door, and “waved” his gun around while the woman and her family hid inside.
