Marquise Demond Webb, 25, of Spring, Texas, died on November 5, 2022, in a case that is tied to an earlier fatal shooting aboard an Amtrak train in January 2022. Webb was charged in connection with the train killing of Richie Aaron and later faced additional counts including armed criminal action, vehicle hijacking, and unlawful use of a weapon. He was taken into custody after a multiweek standoff with the Kansas City Police Department.

Reports say Webb pleaded guilty to the murder in September 2023. The Aaron family also pursued a wrongful death suit against Amtrak alleging failures in response, emergency aid and onboard security; a federal jury assigned responsibility primarily to Amtrak and awarded damages. Limited publicly reported details remain about the November 5 death and how it connects to the earlier events.
