"Chicago’s clearance rate – the calculation of cases that end with an arrest or identification of a suspect who can’t be apprehended – dipped to 26 percent in 2016 from 46 percent in 2013, according to the University of Chicago Crime Lab. Most of the killings, largely fueled by gang violence, take place in a smattering of low-income, predominantly black and Latino neighborhoods on the South and West sides of the city."
