Richard Coss was 25 when he was shot and killed inside his Phoenix apartment during a violent early-morning home invasion on December 18, 2021. A verbal dispute with a downstairs female neighbor earlier the same night escalated, and the neighbor later told Richard’s girlfriend she had called someone to take care of the victim. Just before 1 a.m., at least three men, many wearing masks, forced their way into the apartment. During a struggle one of the intruders produced a handgun and shot Richard once in the chest. His girlfriend escaped and called 911; Richard was pronounced dead at the scene.

Phoenix police identified and charged three men in connection with the attack, including 46-year-old Carl Robert Blazak, who admitted being present but denied shooting Richard, and two others who were arrested and charged. Prosecutors described the killing as a gang-retaliation attack and linked one defendant to the Hells Angels motorcycle gang. What information do readers have about Richard, the neighborhood, or the events that night that could help clarify what led to this fatal confrontation?
