Lamanta Reese, a 19-year-old African American male, was shot dead on May 23, 2017, on a porch in Chicago’s Englewood neighborhood. Reports say he was struck multiple times — including wounds to the head, groin, shoulder, and abdomen — and was pronounced dead at Advocate Christ Medical Center in Oak Lawn shortly after the shooting.

Witnesses identified Gates as the shooter; prosecutors charged him with first-degree murder and a judge set bail at $1 million. The shooting was described as rooted in gang rivalry: Reese was said to belong to the rival Lowe Life faction, and social media exchanges — including posts on Twitter and YouTube that taunted rivals — were reported to have escalated tensions between the groups.

Does anyone have information about Reese’s activities online or about the social media exchanges that preceded the shooting?
