A Las Vegas teenager has been charged with the murder of an innocent woman who was caught in the crossfire of a gang fight while out walking her dogs. 

Kevin Perez-Stubbs, 16, faces counts of murder and conspiracy to commit murder. He was arrested last May, when he was 15.

Prosecutors say it is Stubbs who appears in a grainy surveillance video of the attack. 

The gunman is shown hanging out of a window before firing a fatal shot at Shawna McCowan, a 43-year-old who was out walking her dogs. 

After the attack, prosecutors say he searched for news articles about the woman’s death.

The shooting stemmed from an earlier fight between two teenagers at a nearby apartment complex, according to a police report.

One teen had accused another of stealing his Polymer80 slide gun, which was later recovered near the apartments.

The weapon was not only linked to the shooting, but seen in videos posted to social media, where Stubbs-Perez waved it around and pointed it at the camera.

Polymer80 is the largest manufacturer of un-serialized ‘ghost gun’ parts, which are untraceable when used in a crime.

Police identified McCowan as an innocent bystander who was walking on the same sidewalk as two teens who were targeted in a drive-by shooting.

A man who identified himself as McCowan’s boyfriend told police that he saw the two teens walking toward them as they strolled along Bella Lante Avenue.

Suddenly, a person leaned out of the window of a passing car and ‘immediately began firing a handgun’ in their direction.

A bullet struck McCowan in the back and neck as she fled, the report says. Police later recovered over a dozen projectiles from the scene.

Surveillance video first obtained by 8 News Now shows McCowan and the man walking along as a residential street. Suddenly, a black car pulls up with its headlights off.

The vehicle gradually slows down, nearly coming to a stop, as two other people run off down the street. Perez-Stubbs can then be seen leaning out of the car window and firing the gun.

Police say three other teenagers were with Perez-Stubbs at the time of the shooting, including his older brother, 20-year-old Johnathan.

Tyshean Tillman, 19, was driving the vehicle, while 17-year-old Mezarius Finch was also in the car.

Both minors were certified as adults due to the severity of the crime. Records show the three other teens have taken plea deals.

Should a jury convict Perez-Stubbs, the judge will be required to provide parole eligibility in his sentence due to his age, as per Nevada law.

McCowan split her time between Aurora, Colorado, where she worked as a teacher; and Las Vegas, where she worked for United Airlines.

Around the time of the shooting she was visiting friends, her sister, Autumn, wrote on a GoFundMe campaign.

Autumn and many of McCowan’s other family members, including her son and husband, are based in Colorado.

‘Losing a loved one is never easy but the added layer of losing one out of state is something I wouldn’t wish for any family to navigate during a time of grieving,’ she wrote. 

Ashley Ozark, who roomed with McCowan during United Airlines training, described the mother-of-one as ‘selfless.’

‘She would fight tooth and nail for anyone she cared about,’ Ozark said.

‘She was so full of life and the world is a darker without her. I am so sorry to her loved ones for the loss of such sweet and fiery soul.’
