Teens Charged in Fatal Beating of Chicago Man Posted Video on Facebook (AP)
Three Chicago teenagers accused of fatally beating a disabled man and posting video of the attack on Facebook were playing a game that involved finding an innocent victim and trying to knock him out with a punch, investigators alleged in court documents released Monday. Delfino Mora, a 62-year-old father of 12, was attacked in an alley last week while searching for cans that he collected to make extra money for his family. Chicago Tribune Mora was found unconscious in the 6300 block of North Artesian Avenue in just before 8 a.m. Tuesday. An autopsy found that he died of blunt head trauma in an assault. CNN Malik Jones, 16, allegedly was playing a game called “pick ’em out and knock ’em out” when he punched Mora in his jaw, sending Mora to the ground, where the back of his head was cracked by concrete, a Cook County, Ill., prosecutor told a judge during a hearing Monday. Nicholas Ayala, 17, and Anthony Malcolm, 18, used Jones’ cell phone camera to record the attack, picking up the “loud crack of his head hitting the cement,” prosecutor’s spokeswoman Tandra Simonton said. Jones was charged as an adult and is scheduled to appear for a preliminary hearing Monday. Ayala and Malcolm are expected to appear Monday in bond court.

VentureBeat Posting the video to Facebook seems to demonstrate both an outrageous lack of moral sense that is equally matched by almost unfathomable naiveté, as the teens either felt that they were not doing anything wrong, or that authorities would not notice, or both. In a statement given to the Chicago Tribune, the victim’s youngest child said, “They think posting a violent video makes them tough. It’s like they want to get famous.
