Police documents indicate McCowan was an innocent bystander who happened to be walking on the same sidewalk as two teens who were targeted in a drive-by shooting by a car full of teens, including one passenger who leaned out of his window and shot across the roof of the vehicle into the direction of the two walking teens and McCowan. She collapsed in a home’s front yard in the 3400 block of Bella Lante Avenue, off of Valley View Boulevard and Polaris Avenue.
A man who identified himself as her boyfriend told police, that he saw the two teens walking toward them and then he saw a person lean out of a passing car and “immediately began firing a handgun” in their direction, striking McCowan in the back and neck as she ran for cover, the report stated.
Police recovered evidence indicating at least 16 shots were fired. McCowan was the only person hit.
