Jon Robert Ruff, 61, male, White/Caucasian, died after being shot during a daytime disturbance just off Denton’s downtown Square on August 9, 2025. Police were called shortly after noon to the 200 block of West Hickory Street near Elm Street, where the confrontation—described by authorities as beginning on the Square—culminated in gunfire that fatally wounded Jon Robert Ruff. The man who fired the shots had been visiting the area with his family, remained at the scene, and cooperated with investigators.
Denton police identified Jon Robert Ruff publicly in the days following the shooting and noted that he was taken to a hospital, where he died. Subsequent reporting described him as a street musician who had been experiencing homelessness around the Square. An obituary later confirmed his name, age, date of death, and that he died in Denton on August 9, 2025.
Detectives conducted a homicide investigation and presented the case to the Denton County District
Attorney’s Office for an independent grand jury review. On September 30, 2025, the Denton Police Department announced that the grand jury returned a “no bill of indictment,” declining to charge the shooter; with that decision, police closed their investigation. Authorities did not publicly identify the shooter, and no arrest or charges were filed.
Beyond the immediate investigative outcome, public records and memorials filled in pieces of who Jon Robert Ruff had been. Born in 1963, he served in the U.S. Navy and later studied computer science; friends and community members marked his passing in online memorials that recounted his life and ties to the region. Listings that track gun-violence victims also recorded his death in Denton on the same date.
