MARIETTA, Ga. -- Closing arguments are finished in the DeMarquise Elkins first-degree murder trial. The 18-year-old is accused of shooting and killing 13-month-old Brunswick baby, Antonio Santiago.
Police say Elkins and Dominique Lang, 15, tried to rob the baby's mother.
The teenager's defense team wrapped up its case late Thursday, but not before grilling the victim's father, Louis Santiago, about where he was and what he was doing the March morning his son, Antonio, was killed.
The defense attorneys did everything they could to implicate the parents in the crime, even playing on the mother's mental illness, saying it made her an unreliable witness. They said Sherry West's illness made her unable to say for sure Elkins was the one who tried to rob her, the one who shot her son right in front of her.
DeMarquise Elkins and his mother, Karimah Elkins, are being tried together. She's accused of hiding the suspected murder weapon. Both decided not to testify.
Elkins faces life in prison if convicted. A verdict could come this afternoon.
