Carly Gregg, the teenager who shot and killed her mother and tried to kill her stepfather, was sentenced to life in prison on Friday.
A Rankin County, Mississippi jury found 15-year-old Gregg guilty of all charges, with prosecutor Katherine Newman saying Gregg “showed absolutely no remorse.”
The girl was charged with murder and aggravated assault in the March 19 shooting that killed her mother, Ashley Smiley, 40, and injured her stepfather, Heath Smiley, and with tampering with evidence for allegedly hiding a security camera after the shooting.
Gregg was sentenced to life in prison on the first and second counts and 10 years on the third count.

The verdict came after a week of deliberations over the shocking murder of Mr Smiley in his own home.
The incident, recorded on a surveillance camera in the family's kitchen and shown in court on Wednesday, shows the shocking footage nonchalantly showing the 14-year-old girl carry a .357 Magnum handgun into her mother's room and shoot her.

Heath Smiley testified on the stand Tuesday that when he opened the kitchen door, “the gun went off in my face before the door was even open about three or four inches and it all happened really fast from there.”
“The gun flashed in front of my face,” he said. “The gun fired two more times, but after the first shot, my hand was on the gun, so I wrenched it away from Carly.” Police said Heath was shot in the shoulder during the encounter with Gregg.

During the trial, Gregg's defense lawyers did not deny that the girl killed her mother, but tried to prove that she was experiencing a mental crisis and did not remember the shooting.
Expert witnesses also appeared during the five-day trial, providing insight into Greg's mental state.
“Dr. Clark, based on your experience, expertise and your assessment of Carly, do you believe that on March 19th, the day this incident occurred, Carly was able to understand the nature of her actions and know the difference between right and wrong?” attorney Bridget Todd asked Dr. Andrew Clark, a child and adolescent psychiatrist based in Cambridge, Massachusetts.
“I don't think so,” Clark said.

In closing arguments Friday, prosecutor Michael Smith focused on incriminating security camera footage, saying “Greg knew what he did.”
“Folks, there is no doubt that Carly Madison Gregg is the murderer of her mother, Ashley Smiley. There is no doubt that she put a gun to Heath Smiley's head and shot him. And there is no doubt that she hid the camera and tampered with the evidence,” he said.

“She knew exactly what she was doing and she knew the difference between right and wrong.”
“We would love for you to go back there and find her guilty of all three charges, because at the time of the crimes she was not in her right mind,” he said. “She knew exactly what she was doing and she knew the difference between right and wrong.”
