Read the story of how Daniel Hernandez cared for fallen Congresswoman Gabrielle Giffords before medical personnel arrived.
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.
Ron Barber, Giffords' district director, was next to her. Hernandez told a bystander how to apply pressure to one of Barber's wounds.
Barber told Hernandez, "Make sure you stay with Gabby. Make sure you help Gabby."
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.
Hernandez rode in the ambulance with the Congresswoman to the hospital and said she was squeezing his hand. Our prayers are with Giffords, and the presence of mind and coolness under fire (literally) of Hernandez can't be praised enough.
