Odell Williams, a 69-year-old Chester city councilman and retired police officer, was fatally shot on the evening of November 4, 2014, after a confrontation that began when his wife reported a suspicious pickup truck near their home. The truck was occupied by five members of the Roundtree Circle gang who had been planning a robbery of a rival gang member. When that robbery failed, they began to leave and Williams followed them in his vehicle, starting a chase through Chester.

The pursuit ended when the truck turned onto Roundtree Circle and 18-year-old Christopher Moore exited and fired multiple shots from an assault rifle into Williams’s car; one shot struck Williams in the head and his car then crashed into a nearby house. Moore was later identified as the triggerman and charged with murder; four others — Quinton McClinton, Deangelo Roseboro, Derrick Dixon, and Terrance Williams Buchanan — faced related charges including accessory and conspiracy. Moore’s first trial in April 2016 ended in a mistrial; a second trial in July 2016 produced a guilty verdict for murder and weapon possession and led to a life without parole sentence, while other defendants received varying sentences, with some pleading to lesser charges and testifying against Moore.

Were there witnesses on Roundtree Circle who saw the chase or the truck before the shooting?
