On the night of September 9, 2019, gunfire erupted at about 10:30 p.m. at the intersection of East 29th Street and Park Avenue on Kansas City’s East Side. First responders found Antwain Damon Foster, 41, suffering from gunshot wounds; he was pronounced dead at the scene. His death was one of four homicides in a single 24-hour period that overwhelmed local resources and alarmed the community.

Foster, known by the nickname 4Knottz, was a resident of the area and is remembered by family as a devoted father to his children Aniyah and Amir. Funeral services were held later that month at Golden Gate Funeral & Cremation Services. As of late 2025 no suspects had been publicly identified and no arrests announced, and the investigation remains open.
