Sources: 6. Developments: 2. The Noche Suprema boxing and entertainment event in Hermosillo, Sonora, has been indefinitely postponed following a violent incident at the Centro de Usos Múltiples on August 28. During pre-show preparations, armed individuals entered the venue, fired shots, and set fire to the boxing ring. While the attack caused significant material damage, no injuries or deaths were reported. Jose Luis Castillo Jr. confirmed that he and his team returned to Boston “safe and unharmed.” Organizers clarified that the event is on hold rather than canceled, emphasizing that the safety of athletes, artists, and collaborators is the priority. The Sonora State Attorney General's Office is investigating the incident. One working hypothesis suggests the violence may stem from a dispute between two drug trafficking groups, though authorities have ruled out extortion at this stage. Additionally, the Prosecutor's Office noted that some individuals on the event's roster have active police records or outstanding arrest warrants. ## Timeline ### 2026-09-04: Noche Suprema boxing event postponed after venue arson and gunfire The Noche Suprema boxing event in Hermosillo, Mexico, is postponed after the ring was torched and shots were fired at the venue.
