Eduard Avetisyan, 35, was shot to death at his Los Angeles apartment in the Valley Glen neighborhood on July 17, 2021. The Los Angeles County Medical Examiner‑Coroner ruled the death a homicide, listing multiple gunshot wounds as the cause. The shooting happened in the early morning, about 2:40 a.m., at an apartment complex on Coldwater Canyon Avenue.

Reports say Avetisyan and his downstairs neighbor, Onik Derhovansian, had an ongoing dispute over loud music. On the night of the killing, Derhovansian allegedly called Avetisyan down to his unit; when Avetisyan arrived, Derhovansian shot him multiple times and Avetisyan was found deceased. Derhovansian was arrested on suspicion of murder and later charged in connection with the death.

Were there neighbors or friends who knew about the noise complaints or who witnessed interactions between the two men prior to that night?
