An 18-year-old pleaded guilty but mentally ill to killing his mother on Mother's Day in 2011.
Joshua McEachern was sentenced to 27 years in prison for voluntary manslaughter, attempted murder and possession of a handgun during a violent crime, according to 13th Circuit Solicitor Walt Wilkins.
Investigators said McEachern, who was 17 at the time, shot his mother and brother at the family's Greenville home after an argument, then called 911 to report the shooting.
Deputies said he shot 59-year-old Kathy McEachern in the face, then shot 21-year-old Daniel McEachern multiple times in the chest.
Daniel McEachern survived and was at his hearing on Wednesday along with his sister Debra Davis, who asked for leniency for Joshua McEachern, Wilkins said.
Wilkins said a clinical psychiatrist presented testimony that Joshua McEachern suffers from autism and was diagnosed with Asperger's disorder, allowing the court to accept Joshua McEachern's guilty but mentally ill plea.
Joshua McEachern will have to serve 85 percent of his sentence before he is eligible for release.
