Five Mexican children between the age of 11 and 15 have murdered a 6 year old. "They took his eyes out, they broke his lip, they cut his cheek and stabbed him 27 times on the back", said the kid's aunt.
"Neighbors said that the older of the teens, the group leader, attacked a neighbor with a machete a week prior to the murder"
