An 18-year-old man was convicted of murder in the shooting of a baby who was riding in a stroller alongside his mom in a town in coastal Georgia.

Jurors deliberated about two hours before finding De'Marquise Elkins guilty in the March 21 killing of 13-month-old Antonio Santiago in Brunswick. The man's mother, Karimah Elkins, was on trial alongside him and was found guilty of tampering with evidence but acquitted of lying to police.

De'Marquise Elkins' attorney asked for bond for his client while they appealed, which a judge denied.

Prosecutors said Elkins killed Antonio in an attempted robbery. The baby's mother, Sherry West, also was shot.

Another teen, 15-year-old Dominique Lang, is also charged with murder in the case and is set to be tried later.

Sherry West testified during the two-week trial that she was walking home from the post office with 13-month-old Antonio Santiago in a stroller on the morning of March 21. She said a gunman demanding her purse shot her baby in the face after she told him she had no money.
