Tyler TX (KETK) — The tragic shooting at Sandy Hook Elementary school still raises many questions.

But mainly why did this happen?

Reports now show the shooter, Adam Lanza, was a fan of violent video games.

There has been lots of studies trying to figure out if violent movies and video games cause people to act violently.

But, researchers still have many questions and no clear answers.

"It just doesn't make sense. We try to understand an irrational world with logic it doesn't work," said Psychologist Steven Westmoreland.  

Researchers have been looking into past shooter's interests to see if the media has anything to do with their violent outbreaks.

We asked some East Texans their thoughts about this issue.

"Growing up as a kid I played some of them and I'm not running around doing what some of these idiots are doing."

"Everybody makes their own decisions. It's not necessarily based on if they are playing a video game or not."

New reports show Lanza liked to play the bloody video game Call of Duty.

Westmoreland says human beings are visual learners.

When we see something we are most likely to copy.

"With video games, they just become addictive. Most people spend hour upon hour and that's like repetitious learning. If you study multiplication tables 10 hours a day they would be really deeply ingrained in your brain."

But how do you keep a child away from violence?

90% of movies and 68% of video games depict violence.

It is basically impossible to live in a violence free world.
