Daniel Hernandez, a 20-year-old intern for Gabrielle Giffords, ran toward the scene of the shootings.

The Arizona Republic reports:

Hernandez said he moved from person to person checking pulses.... One man was already dead. Then he saw Giffords. She had fallen and was lying contorted on the sidewalk. She was bleeding.

Using his hand, Hernandez applied pressure to the entry wound on her forehead. He pulled her into his lap, holding her upright against him so she wouldn't choke on her own blood. Giffords was conscious, but quiet....

Hernandez used his hand to apply pressure until someone from inside Safeway brought him clean smocks from the meat department. He used them to apply pressure on the entrance wound, unaware there was an exit wound. He never let go of her...

"Of course you're afraid, you just kind of have to do what you can.... You just have to be calm and collected... You do no good to anyone if you have a breakdown. . . . It was probably not the best idea to run toward the gunshots, but people needed help."
