August 11, 2025
On Aug. 6, a Kershaw County jury convicted Quinterra Siriwat of murder and possession of a weapon during a violent crime. The Honorable Heath P. Taylor sentenced Siriwat to life in the South Carolina Department of Corrections.
On Dec. 17, 2020, dispatchers received a call about a shooting at a Lugoff home. Kershaw County Sheriff’s Office (KCSO) deputies found 36-year-old Vidal Bastien lying on his bed with multiple gunshot wounds.
Sirwat lived at the home with his mother and Bastien, who were engaged.
Siriwat claimed he had been outside with his mother when he heard shots. He said a man ran out of the house before leaving in a gray car. The defendant later identified the man as an ex-boyfriend of a family member.
An investigator asked Siriwat and his mother to follow him to the sheriff’s office for interviews. As they left, a deputy noticed that Siriwat had changed clothes and taken a small bag from his room.
Despite drifting in and out of consciousness, Bastien told deputies Siriwat had shot him.
Deputies later located the man Siriwat had accused and quickly cleared him of any involvement.
Bastien died shortly after arriving at the hospital.
When Siriwat was confronted with Bastien’s statement, Siriwat again denied involvement and blamed the family member’s ex-boyfriend.
When asked about what was in the small bag, the defendant claimed it was nothing important, but later admitted to investigators there was a gun in the bag and confessed to the shooting.
Siriwat told investigators he had argued with Bastien, became frightened, and opened fire. A pathologist later confirmed Bastien had been shot six times.
The Fifth Judicial Circuit Solicitor’s Office, represented by Senior Assistant Solicitor Dale Scott and Assistant Solicitor Michael Bradbury, prosecuted the case and was assisted by Solicitor’s Office Investigator Chris Davis.
