The family of the victim identified him as 43-year-old Joel Villarreal.
They're devastated and gathered in the same place their loved one was shot and killed just 24 hours earlier.
"The morgue told us he was there, but they wouldn't let us see him. I just want to see him," Villarreal's sister, Veronica Gonzales, said.
Gonzales said the family has only learned bits and pieces of what happened to Villarreal from people across the community.
"So my brother went over there to help him, and he got shot. And he lost his life to go help somebody else," Gonzales said.
Joe Luis Villarreal said his brother was the kind of person to help others.
"At the end of the day, he was a good man. He would give the shirt off his back," he said.
Police are still trying to connect the dots to figure out who is responsible and how things escalated to this deadly level.
A good Samaritan nurse, who wanted to stay anonymous, told ABC13 she saw the man lying on the floor and stopped her car. She said she stayed with the 43-year-old until paramedics arrived and took him to the hospital.
"He didn't deserve that, and I'm not going to stop until I find out what happened to him. And they're going to pay. I'm going to make sure they pay," Gonzales said.
They sent balloons straight to heaven on Wednesday night as the family tries to wrap their head around their new reality.
