Latrell McMahon was 18 when he was fatally shot during an altercation on June 17–18, 2016, in the 3400 block of West Madison Street in Chicago. The shooting happened inside a minivan after a confrontation with his 17-year-old cousin, Keshawn Freeman. McMahon was struck once in the chest and pronounced dead at the scene.

A 16-year-old cousin was also struck in the shin and treated at Mount Sinai Hospital. Witnesses inside the van and the surviving cousin identified Freeman as the shooter. Freeman was charged with first-degree murder and aggravated battery with a firearm and was held in lieu of $200,000 bail. He claimed self-defense, but witness statements and other evidence reportedly contradicted that account.

Who has information about the minutes before the confrontation or about the people who were in the van that night?
