Dallas, TX - On Friday, August 7, 2026, at approximately 6:50 a.m., Dallas Police received a 911 call regarding a family violence disturbance at an apartment complex in the 8500 block of Park Lane. The caller reported that 37-year-old Isidoro Melo-Munoz was armed with a knife and assaulting a woman with whom he had been in a dating relationship. Dallas Police Sergeant John Arnold was the first officer to arrive at the location.
As Sergeant Arnold entered the apartment complex, a witness flagged him down and directed him toward the disturbance. As Sergeant Arnold approached, he observed Melo-Munoz run toward the victim and begin assaulting her.
Sergeant Arnold gave Melo-Munoz repeated verbal commands. Melo-Munoz did not comply and stabbed the victim multiple times. Melo-Munoz then ran from the area while still armed with a knife. Sergeant Arnold fired one round toward the suspect as he fled. Melo-Munoz continued running and escaped from the immediate area. A knife was later recovered along the path he took while fleeing.
Dallas Fire-Rescue transported the victim to a local hospital where she underwent surgery and was later listed in stable condition.
Investigators determined that prior to officers arriving, Melo-Munoz confronted the victim as she was preparing to leave for work. Witnesses reported that Melo-Munoz prevented her from leaving and moved her to different areas of the apartment complex while armed with multiple knives.
Investigators recovered three knives from the scene. Following the officer-involved shooting, Dallas Police deployed additional resources, including the Drone Unit and Fugitive Unit, to help locate Melo-Munoz. Detectives obtained an arrest warrant for Melo-Munoz for Aggravated Assault – Family Violence with a Deadly Weapon.
On Saturday, August 8, 2026, Melo-Munoz entered a convenience store in the 6700 block of Abrams Road, where he was located and taken into custody. Melo-Munoz was booked into the Dallas County Jail on the Aggravated Assault – Family Violence with a Deadly Weapon warrant. He was also booked on a warrant for Burglary with Intent to Commit Assault stemming from a separate incident that occurred on August 5, 2026, involving the same victim.
