• Sixteen-year-old Aidan Zingg, an AMA national champion and Kawasaki Team Green rider, was fatally injured June 28 after being run over by multiple bikes and left unconscious on the track for two laps.
• Mammoth Lakes Police Department and the Mono County coroner are jointly probing the accident, with an autopsy still pending to clarify cause of death.
• Zingg’s parents report that witness accounts from fellow riders conflict with race officials’ statements, prompting questions about the timing of flagging and on-track medical interventions.
