UPDATE: No one was inside the building once police made entry.

SUSPECT IDENTIFIED: PCSD says: "On Friday, September 25, 2026, at approximately 3:45p.m. deputies from the Pima County Sheriff’s Department (PCSD) San Xavier District responded to a domestic dispute at Kay Lynn Drive. Upon arrival, deputies attempted to speak with a male who was armed with a sword; however, he was uncooperative. After multiple attempts to de-escalate the situation, the male, who was still armed with the sword, proceeded walking at a fast pace towards the deputies while ignoring their commands. A deputy-involved shooting subsequently occurred. The suspect was pronounced deceased at the scene. No deputies or other community members were injured during the incident. The male has been identified as 35-year-old Joseph Arnold Vallombroso. This case remains under investigation."

The latest release from MPD says no charges have been filed, which typically means someone is claiming self-defense. Here’s what they say: “On October 1, 2026, at approximately 3:28 p.m., Marana Police Department officers responded to the area of Ina Road and the I-10 Frontage Road following reports of possible gunshots and a separate report of a possible road rage incident. Initial information indicated that a caller heard what sounded like gunshots and subsequently observed an individual fall to the ground. Upon arrival, officers detained a suspect. One victim was treated at the scene and transported to a local hospital with serious injuries. The victim was last reported to be in critical but stable condition. Preliminary information indicates this incident may have stemmed from a road rage incident. At this time, no charges have been filed, as the investigation remains ongoing. There is no ongoing threat to the public. The Marana Police Department is actively investigating this incident and will release additional information as it becomes available. Anyone with information regarding this incident is asked to contact the Marana Police Department.”
