CHICAGO (WLS) — Chicago police are investigating a bold crime spree that included a violent attempted carjacking and nearly a dozen other armed robberies, many of which targeted victims in parked cars. Police said the same vehicle was used in the crimes, which all took place within about a three-hour span early Monday morning. Investigators say each involved several armed suspects approaching victims and demanding their property and threatening force. In one case, a man was shot after refusing to give up his car.
