(KAIR)--A deadly 2021 shooting at a Leavenworth pharmacy leads to the conviction of a Kansas City, Missouri woman.

According to a release from Leavenworth County Attorney Todd Thompson, 21-year-old Brooke Johnson was convicted Wednesday in Leavenworth County District Court on one count of involuntary manslaughter. That comes in connection with an April 14, 2021 shooting in the parking lot of KARE pharmacy, located on Leavenworth’s South 4th Street.

Sentencing for Johnson is scheduled for November 30 in Leavenworth County District Court.

According to Thompson, she faces up to 34-months in prison.

The release explains that Johnson used social media to arrange the sale of a gun to three Leavenworth County residents, but actually intended to sell them a realistic BB gun, then drive-off with their money.

Thompson says Johnson recruited two juveniles, one being her 12-year-old brother along with a 17-year-old, to assist with her scheme.

Meeting with the would-be buyers in the pharmacy parking lot, the intended targets of the scam realized the gun was fake after handing off $400. One of the buyers opened fire, hitting Johnson’s car multiple times as it sped from the parking lot. One stray bullet struck the car of a woman, with her 6-month-old baby inside, as she drove past the pharmacy, but they escaped injury.

Johnson, realizing her brother had been shot, avoided Leavenworth hospitals, instead driving to Kansas City’s Children’s Mercy, where he was pronounced dead.

Three others involved in the purchase-turned-shooting are currently serving prison time.

That includes Jaylen Thompson, who fired the bullet that killed the 12-year-old. He was sentenced in June to life in prison with a chance to apply for parole after serving 25-years.
