A neighborhood in Duarte, Los Angeles County, was the scene of a fatal incident following a domestic dispute on Wednesday evening. FOX LA reports that a woman was assaulted by her ex-boyfriend with a tire iron near the intersection of Crestfield and Maynard drives. The confrontation escalated when a resident intervened to help the woman, leading to the assailant's unexpected death.

The neighbor, who intervened, reportedly knew both individuals as all three had grown up together in the area. After stepping in to defend the victim by subduing the assailant, the suspect ceased breathing. According to information obtained by ABC7, the suspect was later pronounced dead at a local hospital. The good Samaritan was initially detained by authorities but later released pending further inquiries.
