From the article:
After receiving a call from one of them, Lewis picked up the four near N. 16th and W. Nash streets. While she stopped at a store to get change, the boys walked to an alley where Lewis met them..
When she pulled out several bags of marijuana, one of the boys not charged punched Lewis, who spun around and grabbed Capehart.
After Lewis and Capehart fell, one of the boys yelled "gun" before they ran away and heard a gunshot.
Lewis told a detective she began selling marijuana about two weeks before to get money for a car and bought the .22-caliber semiautomatic pistol for $75 for protection.
She also said she did not fear for her safety during the incident and that she shot Capehart because she did not want to have her money or marijuana taken from her.
