The Chaos Surrounding Shooting in Tucson

The Chaos Surrounding Shooting in Tucson

President Obama and the First Lady lead a moment of national silence for the victims of the massacre in Tucson.

A bell tolled as they bowed their heads for more than a minute outside the White House. They then walked solemnly back inside.

Hundreds of members of Congress packed the Capitol steps to honor the 6 people killed and 14 wounded in Saturday's horrific shooting, including Congresswoman Gabrielle Giffords.

INSIDE EDITION has obtained this last photograph of Giffords taken just 5 minutes before she was gunned down. She's posing with a constituent.

Sheriff's deputies still have the shopping area locked down as the FBI continues its investigation of the deadly rampage. And for the first time, you can see where the shooting occured. The crowd was gathered around an umbrella when the gunman walked up and opened fire.

The 911 calls made show the ensuing chaos. Even the 911 operator can't believe what's happening.

Caller:  "We need more than one ambulance, there is more than one person down."
911 Operator:  "Is anybody injured? Did you say Gabrielle Giffords was hit?"
Caller:  "Um, she's hit. I do believe she's breathing. There's multiple people shot."
911:  "Okay. Oh my god."

After the gunman, 22-year-old Jared Loughner, opened fire, there were moments of great individual heroism.

20-year-old Daniel Hernandez, who had just signed on with Giffords as an intern five days earlier, rushed to her side and held her hand as she was rushed to an ambulance.

Hernandez told INSIDE EDITION, "She is definitely a fighter, so I wasn't surprised when, even after something as severe as a gunshot to the head, she was still conscious and still fighting for her life."

61-year-old Patricia Maisch is credited with saving many lives because she knocked away the gunman's extra magazine of ammunition before he could reload.

"It came out of his hand and landed on the sidewalk and I managed to get it before he did," said Maisch.

And Joe Zamudio is one of two men who tackled Loughner and overpowered him. Zamudio said, "I was more concerned for all the people who were hurt. Everybody was crying and screaming and bleeding. It was horrible."

Loughner left this chilling message on his MySpace page: "Dear friends ... please don't be mad at me."

He's now charged with one of the most shocking shooting sprees in U.S. History.
