Police said Ashley Porter, 34, drove to a medical marijuana dispensary in Tulsa, Oklahoma, on Friday evening and parked, the Tulsa World reported.
A number of people were outside the business, including the owner who was speaking with a man in a truck, Tulsa police Lt. Brandon Watkins told the paper.
The truck was parked behind the dispensary owner's vehicle, which blocked a lane of traffic in the parking lot, Watkins added to the World.
"It made her angry that the pickup truck was blocking her access," he told the paper, adding that there was still space to maneuver in the parking lot.
What happened next?
Porter didn't exit her vehicle, and no one came to her vehicle, the World reported — but Porter did exchange words with people outside the dispensary before driving away.
But apparently she didn't leave for long.
The paper said Porter returned about three minutes later, allegedly pulled a gun, and opened fire. Watkins told the World she was shooting from her car at the medical marijuana dispensary owner and the truck owner.
Good guy with a gun reacts
Another person also standing outside the dispensary — reportedly a concealed carry license holder, the paper said — fired at Porter, who was found dead at the scene. The man who shot her told responding officers he did so after she began shooting at customers, the World reported.
Detectives questioned the man at the police department, and he was later released, the paper said.
Porter was convicted in 2017 of reckless conduct with a firearm, pleading guilty after an arrest on a domestic assault and battery complaint, the World said.
