Countess Clemons, 21, surrendered to Chattanooga police on an attempted first-degree murder charge Friday afternoon.
According to a police report, Clemons tried to fight with another woman at 11:20 a.m. Tuesday in the 1300 block of Cypress Street Court.
When the woman refused and started to walk away, Clemons pulled a black, semiautomatic pistol from an acquaintance's handbag and fired several rounds at the other woman, according to a police affidavit.
The second woman, who is about six months pregnant, fell while trying to run away from Clemons. The woman was taken to Erlanger hospital after complaining of back and stomach pain, but the affidavit did not specify if the shots struck anyone at the scene.
Multiple people in the area, including small children, were forced to flee for fear of being shot, the report stated.
Clemons and her acquaintance left on foot before police arrived. Clemons later called police and turned herself in Friday afternoon.
Clemons was booked into Hamilton County Jail on one count of attempted first-degree murder, one count of aggravated assault and one count of reckless endangerment.
Her bail was set at $250,000.
