Testimony delivered Monday in an ongoing murder trial at the Dubuque County Courthouse revolved around threats exchanged between multiple parties prior to a fatal 2022 shooting. 32 year old Keywani Evans of Freeport is charged in Iowa District Court of Dubuque County with first-degree murder and first-degree robbery in relation to the fatal 2022 shooting of 20-year-old Taiwon Jackson Jr., of Dubuque. Prosecutors rested their case Monday after calling their final witness, Dubuque Police Department investigator Nick Schlosser. Schlosser testified to carrying out initial interviews with Evans after his arrest. Jurors saw clips of those interviews from Schlosser’s body camera footage, where Evans stated he could not exactly recall the events leading up to the shooting but that he believed Jackson was armed leading up to the incident.Â
