Three of the four homicides in Logan Square that made news recently occurred in Beat 1413, which had the most homicides in Chicago in 2003; the fourth was just north in Beat 1412. The Trib had a long piece on Beat 1413 in early 2004 which reads virtually the same (“The split personality of Logan Square” vs. “Thriving area still harbors deadliest police beat of city”). The MSN group on Logan Square has some info on the gangs (active and historical) in the area. recently added an interactive map that has more detail on the various sub-gangs, one of which is called the “Insane Orquesta Albany,” which very allegedly started as a high school salsa band.
