Michael Smith, 33, was fatally shot on January 27, 2016, in front of his Brookfield, Illinois, home just hours after testifying in a criminal case. He was sitting in his car around noon when another vehicle approached and someone inside opened fire. Smith worked as a security guard and was described by neighbors as a quiet, dedicated father who left behind a wife and a young son.

Investigators tied Smith’s killing to the testimony he gave that morning. Authorities allege Smith was a witness in a case involving Comfort K. Robinson, charged with armed habitual criminal and unlawful use of a weapon by a felon, and that Robinson, with Jermaine Douglas and DeJuyon M. Johnican, conspired to prevent Smith from testifying. Douglas is accused of firing the shots; he was arrested after a car chase that ended in a crash. Robinson and Johnican were also taken into custody and charged with first-degree murder, with Douglas held without bail and the others’ bail set at $250,000 each.

The community rallied around Smith’s family after the killing. Does anyone have information about Michael Smith, his routine that day, or the events around the shooting?
