Robert A. Bub Witmer, 43, was fatally shot in the 2600 block of Nicholson Avenue in Kansas City, Missouri, on April 16, 2017 — Easter Sunday. A dispute between Witmer and another man escalated into gunfire that killed Witmer. A witness said Witmer had picked up a rock during the argument and that the other man threatened to shoot him before the shooting occurred. A protection order had been filed against the accused on March 1, 2017, which barred that person from possessing a firearm.

The investigation identified 30-year-old John Williamson of Kansas City as a suspect. Williamson was arrested and charged with one count of second-degree murder, one count of armed criminal action, and one count of violating a protection order; bond for the protection order violation was set at $200,000. A preliminary hearing was scheduled for May 3, 2017.

Witmer’s family described his death as a sudden tragedy on a day meant for celebration. Does anyone have information about Witmer, the confrontation on Nicholson Avenue, or the events that led up to April 16, 2017?
