MARIETTA, Ga. -- A jury heard more than seven hours of testimony Tuesday, from the mother of a murdered baby.
Sherry West testified in the trial of the teenager accused of shooting her son, Antonio Santiago, between the eyes.
West relived the 13-month-old's murder on the witness stand, often finding herself on the defensive.
"He asked me if I wanted him to shoot my baby. And I said 'please don't shoot my baby'," she sobbed.
Santiago was killed March 21, the same day West said she came face to face with DeMarquise Elkins, 18.
She said she was walking home from the post office, pushing her baby in a stroller, when Elkins pointed a gun at her and demanded her money.
"I tried to stop him. And I put my arms over my baby, but he still shot him," said West.
After that, the questioning got personal. Public Defender Kevin Gough questioned West's ability to accurately remember things. He said it was a side effect of medications she takes for mental illness.
She admitted she was bipolar, suffered from post traumatic stress disorder, and borderline personality disorder.
Gough took it a step further, suggesting she was a drug addict and a bad mother.
He asked her, "Were you on cocaine the day that your child died?"
West said, "No. And I never starved my children either."
The defense is trying to poke holes in her story, trying to create a reasonable doubt that Elkins is not guilty. That's all they need to keep the teenager out of prison for the rest of his life.
But West is sticking with her story. She said DeMarquise Elkins killed her baby even after she begged him not to.
The judge finally called it quits around 7:30 p.m. Tuesday. But the defense isn't finished yet. West will be back on the witness stand Wednesday.
Last week, we heard from the second teenager charged with the baby's murder. Dominique Lang, 15, also testified how Elkins tried to rob Sherry West and how he counted down from five before firing the fatal shot between her baby's eyes.
Lang is also charged with murder. He will be tried separately.
