Calvert L. Antwine, 32, was found dead inside an overturned SUV near 13th Street and Virginia Avenue in Kansas City, Missouri, on the afternoon of March 20, 2014. First responders pronounced him dead at the scene; the Kansas City Police Department classified the death as a homicide. Witnesses reported a silver Dodge Charger chasing Antwine’s vehicle, with occupants of the Charger firing shots at the SUV before it crashed and rolled onto its roof. The Charger’s occupants fled and no arrests were announced, and the case later went cold.

Years after the killing, some investigative material and witness statements tied a man identified as Calvert Papoose Antwine II to the 2004 murder of rapper Mac Dre in Kansas City, and raised the possibility that Antwine’s 2014 death could have been retaliatory. Law enforcement has not publicly named suspects or made arrests in Antwine’s homicide. If anyone has information about the chase, the silver Dodge Charger, or the people involved that afternoon, please share what is known with investigators.
