Cook County, Il., Sheriff Tom Dart says the jail is nearly full, and he's concerned the facility will be bursting at the seams as summer months approach and arrests typically rise with the mercury, the Chicago Sun-Times reports. Last week, the jail was almost 96 percent full, with a daily population of 9,721. “That will become a humongous problem for me come June, July and August,” Dart said. A confluence of events has prompted the surge in detainees, including a spike in arrests and in the amount of time suspects spend behind bars as their cases wind through the justice system. A recent drop in the number of suspects who go home on electronic monitoring also is pushing up the number of detainees. Dart and Chief Judge Tim Evans blame each other for that decrease. No doubt, Chicago's homicide rate and a crackdown on gun and other violent crimes are the reasons the jail is seeing more detainees, Dart said.
