A New Ellenton woman will spend the rest of her life in prison for the 2017 murder of 74-year-old David Mackie.

Kayla Nicole Moore, 20, pleaded guilty to the charge of murder on July 26, but sentencing was delayed until Thursday.

Second Judicial Circuit Judge Doyet A. Early III sentenced Moore to life in prison Thursday, saying "I've never had a person stand before me as cold as you are."

Prior to sentencing, several members of Mackie's family spoke before the court.

Earnell Mackie, David's son, was first to speak Thursday.

"In 19 years of my life, my dad taught me everything I know," he said. "(David Mackie) loved everybody. If someone needed something, he would give it to them even it was his last. What happened to him shouldn't have ever happened."

Mackie's brother also spoke, saying he felt Moore should spend the rest of her life behind bars, which prompted Moore to interrupt by saying, "That was cute." 

Moore showed no remorse throughout the sentencing Thursday, and when asked by  Early if she had anything to say – she responded with, "I don't have nothing to say. What is there to say?"

Early then asked if there was anything she would like to say to Mackie's family, to which she responded, "No."

Mackie's family erupted in applause after Early delivered his sentence Thursday.

Moore had no family members in court to support her or speak before the court.

Investigator Brendan Egan, with the Aiken County Sheriff's Office, investigated the murder and also had a few things to say about Moore on Thursday, describing her as "cold-hearted."

"This is one of the most cold-hearted crimes I've ever witnessed," Egan said. "Speaking with her during my investigation, she showed no remorse and has no accountability for what she did."

Lakisha Davis, Mackie's step-daughter, went as far as to say Moore had "no soul" and couldn't even say she was sorry for her crime.

Charles Hayes, Moore's attorney, noted Thursday a mental evaluation showed Moore as having an antisocial personality disorder, which is a mental condition in which a person consistently shows no regard for right and wrong and ignores the rights and feelings of others. 

Moore was also originally charged with robbery while armed with a deadly weapon, second-degree arson, conspiracy and grand larceny of $5,000 or more, according to jail records. Those charges were either dismissed or dropped for her guilty plea in July.

However, her co-defendant in the case, 19-year-old Jayson Antonio Miles, of Aiken, is still facing all those charges. His case has not yet been heard in court. A hearing for Miles will likely be scheduled sometime next year.

On April 22, 2017, Aiken County Sheriff's Office deputies and the New Ellenton Fire Department responded to 1018 Cedar St. around 10:29 p.m. after receiving a 911 call for a residential fire, according to the report.

The 911 caller claimed to have heard a "small explosion" coming from the trailer, which was fully engulfed in flames when units arrived, the report states.

Investigators reported firefighters entered the trailer and found Mackie's body in the back bedroom of the trailer, the report states.

Autopsy results revealed Mackie did not die in the fire, but had died from blunt force trauma and sharp force injuries to his body, according to Aiken County Coroner Tim Carlton.

Solicitors said investigators determined Mackie had been hit on the head multiple times with a hammer.

At the scene, investigators spoke with several of Mackie's family members who claimed Moore had been staying in the trailer.

Mackie owned the trailer, but had been letting Moore stay there for free because she had no other place to go.

Following Mackie's murder, Moore and Miles took Mackie's vehicle and fled to Georgia until it broke down and they had to walk, solicitors said.

On April 23, 2017, the Morgan County Sheriff's Office found the vehicle abandoned on the side of the road. Moore and Miles were then located a short time later at a Waffle House in Conyers, Georgia.

They were both arrested by the Rockdale County Sheriff's Office on grand larceny charges associated with Mackie's stolen vehicle.

Moore and Miles were then extradited to the Aiken County detention center on May 5, 2017.
