On the evening of November 17, 2025, Brianna Sanchez, 34, was fatally shot at a large multi‑building apartment complex at 750 East Third Street in Pomona. Police were called just after 6:40 p.m.; officers found two adults with gunshot wounds somewhere within the sprawling property. Paramedics and officers attempted to render aid, but Brianna Sanchez was pronounced dead at the scene. The Los Angeles County Medical Examiner later confirmed her death was due to gun violence in Pomona on November 17.

The second victim, identified days later as 57‑year‑old Benjamin Aguilar Orozco, was transported to a hospital and initially survived but later died of his injuries. Pomona Police Department homicide detectives are treating the double fatality as an active homicide investigation. Reporting indicates detectives believe the two adults were in a relationship and that the violence arose in a domestic context, but officials have not released a full narrative, named a third‑party suspect, or announced any arrests.

An online memorial page for Brianna notes she was lost to gun violence and shows many virtual candles from friends, family, and strangers. Does anyone who knew Brianna or lived at the East Third Street complex have information about that November evening?
