Winnsboro, SC – A York man is facing serious charges following an alleged attempted armed robbery at a Fairfield County grocery store that authorities say unfolded in front of a cashier.
According to the Fairfield County Sheriff’s Office, the incident allegedly occurred Wednesday, March 18, 2026, at the Food Lion located along U.S. Highway 321 in Winnsboro. Investigators allege that 19-year-old Trevor Zain Demby entered the store with a female companion and approached the checkout line before the situation escalated.
Authorities allege Demby removed a handgun from his hoodie and placed it on the conveyor belt, pointing it in the direction of the cashier. The cashier reportedly told investigators she heard a statement referencing the cash drawer but was too stunned to fully comprehend or respond before Demby allegedly retrieved the weapon and exited the store. The female, identified as a juvenile, followed him out.
Surveillance video from the store allegedly corroborates the encounter, showing Demby placing the firearm on the counter while the cashier appeared visibly shaken. Although the footage did not include audio, investigators say the visual evidence supports the sequence of events described.
By Friday, March 20, 2026, deputies had developed leads and identified both individuals. Investigators located the pair at a residence within Fairfield County later that day. Demby was taken into custody without incident, while the juvenile was released to a parent due to her age.
Demby has been charged with attempted armed robbery and possession of a weapon during a violent crime. He remains detained at the Fairfield County Detention Center. Authorities say the investigation remains active, and additional charges could be forthcoming.
Anyone with information is urged to contact the Fairfield County Sheriff’s Office.
