Curtiss Walker, 29, died in a workplace shooting at a Discount Tire on Grape Road in Mishawaka, Indiana, on the afternoon of January 28, 2026. Walker, a former U.S. Marine and the store’s general manager, was inside a closed office with two other people when a friend’s semi-automatic handgun discharged. The single gunshot struck Walker in the head; he was pronounced dead from the injury.

Mishawaka Police and Fire responded shortly after 5:00 p.m. There were other employees and customers in the store but no one else was injured. Investigators interviewed the two people who had been in the office with Walker, and the Mishawaka Police Department found no evidence of foul play. The St. Joseph County Coroner’s Office ruled the death an accident. Authorities said it was unclear whether Walker or the gun’s owner knew the handgun was loaded; no arrests were made.

Walker was a husband and father of three young children. Does anyone who worked at or visited that Grape Road store that day have information about what happened in the office?
