"So that's when I noticed he had been shot once in each arm. I took it upon myself to let him know that I'm going to try to stop the bleeding. I took my shirt off, tied it around his first initial gunshot wound on his left arm. I took his shirt off, tied it around his other arm where the other gunshot wound was," he said.
The bartender had also been shot in the back.
