BRUNSWICK, Ga. -- The teenager who killed a Brunswick baby will never know freedom again.
A judge sentenced De'Marquise Elkins, 18, to life in prison without the possibility of parole.
It was the maximum punishment he could receive for shooting 13-month-old Antonio Santiago between the eyes while trying to rob the baby's mother back in March.
At Thursday's hearing, the mom, Sherry West, briefly took the stand to read a poem about how much she misses her little boy.
West said, "His first word was never heard. His first sentence was never said. He never got to sleep in a toddler bed."
Elkins' attorneys argued that life without parole, for a teenager, amounts to death.
Public defender Kevin Gough said, "Life without parole for a juvenile is cruel and unusual punishment."
Gough plans to appeal.
Elkins' accused accomplice, 15-year-old Dominique Lang, is still awaiting trial.
His mother, Karimah Elkins, was tried at the same time as her son. While the same jury found her not guilty of making false statements to police, they did find her guilty of evidence tampering.
She tried to cover up her son's crime by throwing the gun he used in a saltwater pond.
She is still awaiting sentencing. She faces 10 years in prison.
