Chicago Weekend − 72 Shot Over The Weekend, 13 Killed

At least 72 people were shot, including 12 fatally, over the weekend in Chicago, marking a chilling eruption of violence for a city that has struggled with murders and shootings in recent years even as the national homicide rate hovers near historic lows.

Police are also investigating a thirteenth murder— a 32-year-old woman who was found dead around 9 p.m. Sunday in a bathtub with her hands and feet bound. Police did not reveal how the woman was slain.

No arrests have been been made in any of the incidents, but police said investigators have strong leads for some of the shootings.

"There is a shortage of values about what is right, what is wrong," said Mayor Rahm Emanuel. "We as a city, in every corner, have an accountability and responsibility. If you know who did this, be a neighbor. Speak up."

The violence, which police say is primarily fueled by gangs, disproportionately impacts several swaths of low-income black and Latino neighborhoods on the city’s West and South Sides.
