The woman says she saw the mother lay the child on the ground to try to revive him with CPR.

"Yes, I heard the shots. Somebody shot this child," the caller said. "She's got him on the ground. Please, we need everything we can get."

One caller solemnly tells an operator: "No, the baby's not breathing." He says the child was shot "right between the eyes."

A woman can be heard screaming in the background just before police arrive and sirens drown out her cries.

No callers reported seeing the shootings, and police said the three calls were the only ones they knew of.

At her apartment Saturday, West had filled several bags with her son's clothes and diapers to donate to charity. She said she hopes prosecutors pursue the death penalty in the case.

"My baby will never be back again," West said, sobbing. "He took an innocent life. I want his life, too."

Debra Obley says she never imagined she'd have two ties to the investigation into the murder of the toddler.

"I feel sad I'm being threatened, yeah I'm being threatened by people saying they are going to kill me or have people to kill me, because I'm a snitch," said Obley.

Obley's nephew is the 14-year-old accused of being an accomplice to the murder.

She tells Channel 4 that she gave Elkins a ride from her mother's house, not knowing who he was.

"When he got in the car, he laid down in the backseat," said Obley. "He kept looking around, peeping up and I said, 'Boy, what you doing? You skipping school?' You know, he said 'No ma'am.'"

When she started asking for more questions, Obley said Elkins cut the ride short.

"When he got out of the car, he had something hid up in his pants. It was a gun," said Obley.

Obley says she felt something wasn't right, so she asked her nephew about it.

"I said...if you've got something to do with this little baby, you can't talk to me. I'm your auntie," said Obley. "He said 'Auntie, I don't even know the boy. I don't have anything to do with that.'"

Even though he wouldn't talk to her, Obley decided to talk to police. While it's hard to see her nephew behind bars, Obley said she feels she did the right thing.

"It's wrong. That was a baby. That baby can't come back," said Obley. "That mama will never get that baby back. Whoever did it deserves to be behind bars."

Obley said she doesn't believe her nephew would have fired at anyone. She hasn't talked with him since.
