The grandmother parked her grandson in the shopping cart and was looking at items, when the 55-year-old suspect, Timothy Wall, walked up.

- There has been a shooting.

- Who was shooting?

- I couldn't recognize him. He's wearing all black and sunglasses. He just shot a child.

MANUEL BOJORQUEZ: He shot the one-year-old first, and then turned toward the grandmother.

TALAL MASRI: The grandma instinctively jumps in trying to stop him, she struggles with him. His gun jams, she was able-- he was able to overpower her, push her down to the ground and he shoots her down while she's on the ground.

MANUEL BOJORQUEZ: Wall then turned the gun on himself. The carnage was over in less than four minutes. The suspect did not know the victims.

RIC BRADSHAW: There was a chance this could be stopped. You know why? The reason is, he's on Facebook. He has said, "I want to kill people and children." You think a damn soul told us about that? No.

MANUEL BOJORQUEZ: There is now a growing memorial for the victims outside this Publix store where deputies say surveillance cameras captured the entire incident. They say the suspect had declared bankruptcy earlier this year. His ex-wife telling them he had recently started to act strangely. Nora?
