Teen girl on trial for mother's chilling murder: Courtroom drama unfolds

The trial of Carly Gregg, a teenager accused of murdering her mother, began unusually. The 15-year-old, dressed in a navy blue outfit, couldn't suppress nervous laughter while sitting on the defendant's bench. Later, however, tears flowed. Her lawyers, maintaining serious expressions, accompanied her on both sides.

Carly Gregg is on trial for the alleged shooting of her mother, Ashley Smylie, which took place in March when Carly was 14 years old.

The prosecution presented a recording showing Carly with a gun, and then gunshots were heard. The footage is chilling. It shows the teenager walking from the kitchen to another room, after which gunshots are heard.

Gregg shot her mother, stole her phone, and returned to the kitchen to text her stepfather. She asked in the message, "When will you be home, honey?" The teenager also played with two dogs.

When an audio recording was played in court, in which a shaken stepfather is heard calling the police, the 15-year-old cried.

Carly's defense is relying on insanity as the main line of defense. An earlier plea deal proposal, which could have resulted in a 40-year prison sentence, was rejected by her.

In addition to the murder charge, Carly Gregg is also facing charges of attempted murder and evidence tampering.
