"We had planned a whole holiday Memorial Day family time here. He wasn't here," Sheri said.
Byron was shot three times, in both legs and his shoulder.
He's already been through several surgeries and blood transfusions today.

"It's trying to put all the events together," Sheri explained. "It happened all so fast."
At first, police labeled Byron as a possible suspect.
Then, as the investigation unfolded, police clarified -- Byron was a good Samaritan, seemingly trying to stop the shooter.
But, for Sheri, the most disturbing part of all is who police have identified as the shooter: 25 year old Dionisio Garza, a 25-year-old veteran.
"A veteran. A nice looking guy," she said. "I mean, what are we doing? What are we doing for our veterans? They, too, have families. They're hurting and we have got to listen. We have to listen."
