Carly Gregg, a 15-year-old from Mississippi, is currently on trial for the murder of her mother, Ashley Smylie. The little girl is accused of murder and attempted murder in connection with a terrible incident that happened earlier this year. In addition to the strange behavior of Gregg in the courtroom, the nature of the crime and the trial itself have drawn attention. The trial started on Thursday. Gregg seemed to have difficulty holding back his laughing at the defense table during the trial. She sat between her defense counsel, who had somber looks throughout the trial, wearing a traditional blue dress. Video footage once showed her female lawyer writing something on a pad, at which Gregg unexpectedly burst out laughing. It's still unknown why she reacted the way she did. The lawsuit centers on an incident that reportedly happened in March, when Gregg, who was 14 at the time, shot Ashley Smylie, her mother. Her stepfather, Heath, was also there when the incident happened at their house. Heath gave a detailed account of the incident and the events that preceded the shooting during his testimony during the trial.Earlier in the week, prosecutors unveiled a crucial piece of evidence: a video clip of the encounter. Gregg is seen in the video allegedly carrying a pistol behind her back before leaving the frame of the camera. Shots are heard a little while later. The prosecution claims that a.357 Magnum handgun was used in the crime and that it was subsequently found at the site. Gregg is accused with attempted murder in addition to the murder allegation. After shooting her mother, she reportedly attempted to kill Heath, her stepfather. Heath lived to testify about the shooting, which shed more light on the situation.Gregg's legal team is pursuing an insanity defense in response to the charges. They argue that mental health issues may have played a significant role in her actions. The defense had previously rejected a plea deal offered by the prosecution, which could have resulted in a 40-year prison sentence for the teenager.It is anticipated that the trial will proceed with more scrutiny of the evidence and witness statements. Gregg is charged with both murder and attempted murder in addition to tampering with evidence, which adds another level of complexity to the continuing legal dispute. Gregg's behavior and the specifics of the terrible events that resulted in her mother's murder continue to be the center of attention as the trial progresses.
