Carly Gregg, a 15-year-old from Brandon, Mississippi, is on trial for the alleged murder of her mother, Ashley Smylie, a high school teacher, which occurred on March 19, 2024. Surveillance footage presented in court captured Gregg moments after the shooting, where she appeared calm while texting her stepfather, attempting to lure him home. Prosecutors allege that the shooting followed an argument over Gregg's marijuana use, which her mother discovered earlier that day. After the murder, Gregg reportedly shot her stepfather in the shoulder when he returned home, but he managed to disarm her. Her defense is claiming insanity, asserting that she was experiencing hallucinations at the time. The case has drawn significant media attention due to the shocking circumstances and the chilling footage of Gregg's actions following the alleged crime.
