A suspected Mexican cartel leader has been arrested after authorities linked him to the livestreamed murder of TikTok influencer Valeria Márquez. Ramón Ángel Álvarez Ayala, better known as “El R-1,” was captured during a federal operation in Atotonilco El Alto, Jalisco, on July 30. Álvarez Ayala is accused of leading Los Rs, a violent criminal cell connected to the Jalisco New Generation Cartel. Mexican officials claim the group helped coordinate the May 2025 killing of 23-year-old Márquez after she split from his son.
