(WTXL) - Two people are dead and nearly a dozen more injured after a gunman opened fire at a video game tournament Sunday in Jacksonville.
The shooting was captured during a livestream of the tournament.
Just moments before the shooting, the livestream captured a laser dot appearing on one player's chest.
Meanwhile, police have identified the alleged gunman as 24-year-old David Katz, who was an avid gamer who regularly competes in big money tournaments.
Why the suspect went on a rampage remains unknown, but witnesses say he lost in this tournament early.
Family Therapist Jane Marks says parents should be aware of what video games their children are getting involved with. But it's also important to measure how much time they spend playing them.
Marks says unchecked video game playing can lead to addiction.
So it's critical that parents make rules about how much time kids can spend playing and then actually enforce them.
"I think for parents out there looking at something like this, they want to make sure that there is balance in their youngsters lives," Marks explained. "It's O.K. to play video games but there must be other things, there must be other experiences, there must be other ways to express themselves."
She said video game addiction could interrupt with the way children adapt to society. If gaming becomes too much of a child's life, it could close off socialization, interaction and social skills.
