Teens' 'Memento' Photo Reveals Disturbing Details in Fatal Rock-Throwing Spree.

One of the three Colorado teens charged in the deadly rock-throwing spree that killed a young motorist last week reportedly had a history of “destructive behavior”. High school senior Joseph Koenig, along with Nicholas “Mitch” Karol-Chik and Zachary Kwak, were arrested this week. Two other motorists suffered minor injuries from the rock-throwing spree. The trio could face additional charges, including attempted murder or assault. They are being held without bond, and their next hearings are set for May 3.
