Yup, I'm in Milwaukee,Wisconsin and just a few months ago a group of "kids" used base ball bats, crates and anything else they could get their little hands on to beat a grown man to death out in the streets
From my understanding, this happened late at night or in the wee hours of the morning (hummmmmmmmm.... why weren't the parents concerned that their kids were out that late, but that's another topic). Apparently the kids were making fun of the man, he hit one of the kids, and then all hell broke loose. It was a mob of children (with a smattering of 18,19, and one 30 year old in the mix) who chased him in the streets, in and out the abandoned houses he tried to hide in and beat him to death. The youngest was 10 years old, but he was found not competant enough to stand trial. Sad and very wierd.
