Authorities in upstate South Carolina have arrested the 19-year-old grandson of a retired couple found slain in their home earlier this month, charging him with two counts of murder in a case that has shaken a small rural community.

The Oconee County Sheriff’s Office said Levi Kevin Jones was taken into custody late Friday and charged in connection with the deaths of Larry Moore, 76, and Sandra Moore, 75, who were discovered inside their residence on Cromer Moore Road near Westminster on Jan. 15.

Jones is also charged with two counts of possession of a weapon during the commission of a violent crime, according to arrest warrants obtained by Fox News Digital. He remains in custody pending a bond hearing.

The couple was found after a family member requested a welfare check when repeated attempts to reach them were unsuccessful. Investigators and the county coroner later determined the deaths were homicides.

According to the Oconee County Coroner’s Office, Larry Moore died from multiple stabbing injuries, while Sandra Moore died from manual strangulation. Autopsies were conducted the following day.

Arrest warrants allege Jones stabbed his grandfather multiple times in the torso and neck and strangled his grandmother, cutting off her airway and blood flow. Authorities said a knife was used during the attack.

Authorities have not provided a motive for the attack.

They were also active members of Calvary Church, where friends described them as regular attendees.

“They were always there,” Stacy Brooks, who attended church, told Fox News Digital. “You expected to see them every time you went. They were faithful people.”

Brooks said the killings have been difficult for residents of the small upstate South Carolina town to process.

“This is a close community, and something like this just doesn’t happen often,” she said.
