Salim Khamo, 66, was a long-time West Ridge small-business owner, described as a devoted father, grandfather and community fixture. An Assyrian refugee who came from Iraq in the early 1990s, he ran J & K Food and Liquor and had recently sold the store to a relative as he prepared to retire and spend time with his wife, three children and seven grandchildren.

On the night of October 17, 2022, Khamo was behind the counter with a cousin when a man rode up on a bicycle, entered and placed a handgun on the counter demanding money. Khamo, who held a concealed-carry license, stepped back to draw his own weapon; the robber fired one shot, striking Khamo in the chest. He was taken to Saint Francis Hospital in Evanston and died of his wound.

Police recovered the suspect’s abandoned bicycle and a cell phone at the scene. Photos on the phone linked it to Sean Dunnavant and to the bicycle and a handgun consistent with the murder weapon; surveillance footage and a community tip led to Dunnavant’s arrest. What details about the night haven’t been shared publicly that might help explain how the suspect was identified?
