CHICAGO – Two men were gunned down in the same day along Chicago’s “Safe Passage” school routes.

The Chicago Public Schools website contends the Safe Passage program is “designed to provide safe routes for students while traveling to and from school,” but recent news reports prove the program might need some tweaking.

Chicago Police report a 21-year-old man took four bullets to the chest on one “Safe Passage” route near Lake Street and Central Avenue in a suspected drive-by shooting at around 8:20 a.m. Monday, and later died at Loyola University Medical Center, the Chicago Tribune reports.

Hours later, around noon, a 28-year-old man was shot in the left thigh while driving down West Palmer Street. Chicago Police Department spokeswoman Nicole Trainor told the Tribune the man was shot at by two people he did not know, and drove himself to Saints Mary and Elizabeth Medical Center for treatment.

CLTV reports the deadly morning shooting occurred near a Chicago Transit Authority train stop, and police described the victim as a “documented gang member.”

Police are now reviewing at least three surveillance video cameras from the area, but currently have no suspects in custody.

“It’s really a shame the way these shootings going on around here, especially when it’s between two schools, an elementary school and a high school,” one unidentified parent of 5- and 6-year-old boys told CLTV as she walked them to school through the crime scene Monday.

“The kids don’t seem to have anything to do to occupy their time, so they try to utilize their time by doing negative stuff,” a local man told the news site. “As a result, innocent people, the kids, are getting hurt.”

The Safe Passage murder in only the most recent in a number of violent incidents that have occurred along Safe Passage routes in the Windy City in the past few years.

ABC 7 News in October 2013 documented 100 serious incidents along Safe Passage routes – from reports of shots fired to gang fights to drug deals – in the first three weeks of school alone.

A few months later, the news site reported on a 15-year-old girl who was beaten and sexually assaulted along a CPS Safe Passage route to Northwest Middle School.

DNAinfo analyzed crime along 64 of Chicago’s Safe Passage routes in September and compared crime data along the routes during the times adult monitors are on duty.

“The analysis found that crime along these routes between 6 a.m. and 6 p.m. on school days dropped 26 percent between the 2012-13 school year and 2014-15, a number confirmed by the Chicago Police Department’s own analysis,” according to the news site.

“There have been 44 percent fewer drug offenses along routes during the 2014-15 school year compared with 2013-14. Robberies are down 34 percent. Batteries are down 22 percent.”

CPS officials at the time touted the fact that there had not been a serious crime along Safe Passage routes during the 6 a.m. to 6 p.m. window.

“We’re able to say we still haven’t had a serious incident involving our students during times that Safe Passage workers are on duty,” district safety and security chief Jadine Chou told DNAinfo in September.
