'I knew she was gone': Witness describes aftermath
After a gunman opened fire at the Allen Premium Outlets, Joshua W. Barnwell, an eyewitness with military experience, rushed to help the wounded.
A woman who was conscious asked him to help her daughter, he said.
"This woman had massive trauma, five to six gunshot wounds," Barnwell told "Good Morning America" on Monday.
He went to the daughter to start chest compressions, he said.
"When I saw the massive amount of blood come out from her when I gave her chest compressions to her back," Barnwell said. "I knew she was gone."
