A family dispute in Anderson, South Carolina, ended with a young man dead and his teenage sister charged in the killing. Deonte Marquez Luster, 27, was shot on Squirrel Drive after a heated argument on January 25, 2025. Authorities were called about 2:30 p.m.; emergency crews found Luster with a single gunshot wound to the chest and he died after being taken to AnMed Medical Center. The Anderson County Coroner ruled the death a homicide.

Investigators say the altercation became violent and identified 18-year-old Ly-Rique Lajada Grayson, Luster’s sister, as the suspect. Grayson reportedly contacted emergency services after the shooting and was arrested and charged with murder and possession of a weapon during the commission of a violent crime. At a bond hearing she was denied bond; family members told the court both siblings had struggled with mental health issues and asked that untreated mental illness be considered.

Does anyone in the Anderson area have information about the events on Squirrel Drive that afternoon or about the family’s situation leading up to January 25?
