MARIETTA, Ga. (CN) - Sherry West, whose year-old baby was shot to death in a stroller, pointed to De'Marquise Elkins from the witness stand Tuesday and said, "I saw him shoot my baby."
Elkins, 18, is charged with the felony murder of 13-month-old Antonio Santiago. He also is charged with shooting West and trying to rob her.
Elkins' mother, Karimah, is being tried with her son, charged with obstructing justice by throwing the gun into a swamp and lying to police.
West testified for 4 hours Tuesday about the shootings on a street in the historic Old Town area of Brunswick, Ga.
If convicted of murder, De'Marquise Elkins faces up to life in prison.
Dominique Lang, 15, also is charged with murder and will be tried separately. He has testified that he was with Elkins when the crime began, but said he ran away when the shooting started and heard, but did not see, the shot the killed the baby.
Also to be tried separately is Karimah Elkins' sister, Sabrina, who is charged with tampering with evidence.
The jury trial was moved from Glynn County to Cobb County because of pre-trial publicity.
Entering the courtroom, West, dressed in black, walked by Antonio's empty stroller, wrapped in evidence tape and brown paper, then sat in the witness chair.
Glynn County Special Prosecutor Andrew Eknomou asked her to tell the jury what happened that day, March 21.
With tears in her eyes at times and a trembling voice, West said she needed a stamp for a letter, so she bundled up her son and put him in a stroller to walk to the post office.
"I dressed him to go out at 8 a.m. It was cold. I put on his sweatpants, sweatshirt, mittens and a hat." She began to weep.
Eknomou prompted: "Didn't you put a cute little hat on him?"
"I put on a hat, it was blue, to match his mittens," West sobbed. A few jury members sobbed too.
West said she spent about an hour at the post office and left around 9 a.m. As she walked home she was approached by two black males.
"I was five minutes from my home. Two boys were walking down the street. We were both walking toward each other," West said.
"I moved to the right, so they could go past me."
West said the two boys were different in height and age.
"One was tall and the other was very short. The tall one looked to be about 15, and the short one looked like he was five," she said.
"The big one approached me and demanded me to give me money. I told him I didn't have any. He repeated it. He said, 'Give me your money.'
"Again, he demanded me to give him my money, and I told him that I had a baby and had expenses and I didn't have any money."
Sobbing, West continued: "He asked me if I wanted him to shoot my baby, and I said, 'Please don't shoot my baby.'"
West said Elkins pulled a gun from the waist of his pants and shot a warning bullet into the ground, then took aim at her.
"He pointed it at me and tried to shoot me in the head and I ducked.
