A Gaston woman has been arrested and charged with murder in connection to a fatal shooting early this morning in southern Lexington County.

Chesnee Labri Mattress, 23, is also charged with possessing a weapon during a violent crime, according to arrest warrants. Lexington County Coroner Margaret Fisher identified the victim as Annette Riley, 44, of Gaston.

“We’re working to determine more about the relationship between the victim and the suspect and what lead to the gunshots but, based on information we’ve gathered so far, this wasn’t a random act,” Lexington County Sheriff Jay Koon said.

Riley was shot in the upper body in front of a home in the 300 block of State Pond Road in Gaston, according to Koon. Deputies responded to the scene about 12:40 Wednesday morning.

“Based on witness statements, investigators developed a solid lead soon after the shooting,” Koon said. “Mattress was arrested without incident at her house about 4:30 this morning.”

Mattress is being held in the Lexington County Detention Center while she awaits a bond hearing.

“Our investigation into the shooting is still open,” Koon said. “We’re asking anyone with information related to the case to share those tips with us by calling Crimestoppers at 888-CRIME-SC.”
