Law enforcement officials say violent video games and an obsession to top the murder count of another serial killer motivated Newtown, Conn., shooter Adam Lanza.
Lanza killed 20 children and six adults at Sandy Hook Elementary school in December.
According to CBS News, two officials said Lanza wanted to surpass the body count of Norwegian killer Anders Breivik, who massacred 77 people in Norway in 2011.
Lanza reportedly chose Sandy Hook because it was "the easiest target" with the "largest cluster of people."
The officials also told CBS News that evidence shows Lanza probably was living out a fantasy based on violent video games he played in his home.
They found a number of violent video games in a blacked-out room in his basement, where he reportedly spent hours playing them alone.
Connecticut Republican Rep. Debralee Hovey, whose district includes Newtown, has called for a 10 percent sin tax on "mature" rated video games. She says the money from the tax should be used to fund mental health education about "the danger of violent games."
Is this a good plan? Melissa Henson, director of communications for the Parents Television Council, talks about this and what steps parents can take to protect their children and teens, on CBN Newswatch, Feb. 19.
