The trial of Carly Madison Gregg, a Mississippi teenager accused of murdering her mother and attempting to kill her stepfather, has concluded with a guilty verdict on all charges. The high-profile case, which drew national and international attention, centered not on whether Gregg committed the acts, but on her mental state at the time. This complex legal battle explored the intersection of mental health and criminal responsibility, raising difficult questions about accountability and justice.

The defense argued that Gregg was suffering from insanity at the time of the killings. Gregg’s stepfather, Heath Smylie, testified that she appeared to have “seen a demon” during the attack, suggesting an altered mental state. He maintained that the girl who committed these acts was not the stepdaughter he knew and with whom he still speaks daily. The defense also presented medical experts who testified about a recent change in Gregg’s medication and her use of THC products, suggesting these factors could have induced a state of hypnosis, rendering her unaware of her actions.
The prosecution, however, painted a picture of deliberate and malicious behavior. Assistant District Attorney Katherine Newman stated after the verdict, “Those crimes were awful. She has shown zero remorse. Zero remorse for what she has done. We don’t know why she committed these crimes, but we know she did and we know that she is a danger to society.” The prosecution’s case relied heavily on home security footage and witness testimony to establish a timeline of events and demonstrate Gregg’s actions before, during, and after the crimes.
Home security footage presented in court detailed the events of March 19, 2024. Video showed Gregg and her mother, Ashley Smylie, a local teacher, arriving home from Northwest Rankin High School around 3:54 p.m. At approximately 4:14 p.m., Gregg was seen walking towards her mother’s bedroom with what appeared to be a gun concealed behind her back. While there were no cameras inside the bedroom, the kitchen camera captured the sound of three gunshots. Ashley Smylie was later found deceased with three gunshot wounds to the head.
Following the gunshots, Gregg was seen returning to the kitchen, seemingly undisturbed by two agitated dogs. She then used her mother’s phone to text her stepfather, asking, “Are you almost home, honey?”
Heath Smylie, believing the text was from his wife, returned home at 5:03 p.m. As he entered the house, three more gunshots were heard. He managed to disarm Gregg, who then fled the scene but was apprehended shortly after by law enforcement.
The prosecution’s case was further strengthened by the testimony of medical professionals. Dr. Jason Pickett stated that he found no evidence of insanity in Gregg. “My opinion is that Carly does not meet Mississippi’s standard for insanity at the time of the events and that she knew the nature, quality, and wrongfulness of her actions during that day,” Pickett testified.
Dr. Andrew Clark, who conducted Gregg’s psychological evaluation before the trial, acknowledged a history of dissociative experiences and diagnosed her with Bipolar II disorder. While he stopped short of offering a definitive opinion on her sanity at the time of the crimes, he described Gregg as being in a “mental health crisis” on March 19th. His testimony, while called by the defense, ultimately did not provide the conclusive evidence of insanity they were hoping for.
The jury ultimately sided with the prosecution, finding Gregg guilty of first-degree murder, attempted murder, and tampering with evidence. She received two concurrent life sentences for the murder and attempted murder charges, along with an additional 10 years for tampering with evidence. This verdict came after Gregg rejected two plea deals for a 40-year sentence, choosing instead to take her case to trial.
Gregg’s legal counsel has indicated their intention to appeal the verdict within the allotted 10-day period. The case raises important questions about the role of mental health in criminal proceedings and the challenges of determining culpability when mental illness is a factor.

This tragic case serves as a stark reminder of the devastating consequences of violence and the complexities of the legal system when dealing with issues of mental health. While the verdict brings a sense of closure to this particular chapter, the larger conversation about mental health and criminal justice continues.
This case continues to draw significant public interest, underscoring the need for further exploration of the interplay between mental health and the legal system.
The family of Ashley Smylie has expressed relief at the verdict, but also profound sadness at their loss. They have requested privacy during this difficult time.
The verdict in this case will undoubtedly have lasting implications for both the Gregg and Smylie families, as they navigate the aftermath of this tragedy. The case also highlights the ongoing need for accessible and comprehensive mental health resources, particularly for young people.
