Nabil Batroukh, a 64-year-old man from Chicago, was killed on September 6, 2014, one of four people who died and five others wounded in a series of shootings that weekend. Batroukh lived in the 7700 block of West 79th Street in southwest suburban Chicago.

The Chicago Police Department opened an investigation but faced challenges: few eyewitnesses and limited concrete evidence made reconstructing the shootings difficult. Batroukh’s family and community were left to deal with the loss, and the incident was cited as part of the broader problem of gun violence in the city.

Does anyone have information about Nabil Batroukh or the shootings that night that could help investigators?
