Teen gets life in prison without parole for killing 4 at Georgia’s Apalachee High School(ASSOCIATED PRESS) – According to AP, a judge on Tuesday sentenced a teenager who killed two students and two teachers in a shooting at Apalachee High School in Georgia to serve life in prison without the possibility of parole. The minimum penalty for murder in Georgia is life with the possibility of parole. “We’ve seen no evidence he has any ability to develop a conscience or any ability ever to fully value human life,” Smith said. Gray had the “mental wherewithal” to mimic details of other mass killings on the day of the shooting, Smith said. Polhamus said she visits her grandson once a week at a youth detention center and that he has improved enormously with treatment and medication.
