Rico Martinez and Javari Long said they were among the first to meet terrified witnesses and victims as they ran from the Landing.
“I [saw] a lady, she got hit in the leg, and they [were] carrying her out," Martinez said.
Martinez said people fleeing told him and Long that a disgruntled gamer started shooting at the Madden video game tournament.
“I've never seen a grown man that shook in my life,” Long said. “The look on everybody’s face. They were terrified; they were frightened."

Long said their first instinct was to start running, but police and paramedics began arriving, so they started taking videos because they're upset over the recent spike in Jacksonville gun violence.
They specifically mentioned the triple shooting that left one person dead outside the Raines High School football game on Friday.

“When I went on live, I wasn’t trying to get attention; I was trying to let people see what was going on in Jacksonville," Long said.
