Joshua Monugian, a 34-year-old male of Latino ethnicity, was shot and killed just before dawn on July 13, 2025, on a quiet residential stretch of the 14800 block of Steprock Drive in La Mirada, California. According to investigators, the trouble began as a dispute between a man and a woman; when Joshua Monugian and another man stepped in to break it up, a vehicle pulled alongside them. A suspect got out and opened fire. Deputies arrived around 3:45 a.m. to find Joshua Monugian fatally wounded; he was pronounced dead at the scene from a gunshot wound to the head, and the case was immediately classified as a homicide. A second victim, a 51-year-old man, was shot in the torso and taken to a hospital, where he survived.
