The parents of Aidan Zingg, a motocross athlete who died in June 2025 at age 16, have filed a wrongful death lawsuit against the organizations involved in their son's fatal race, alleging his death was preventable. Robert and Shari Zingg claim the collision happened as a result of careless race operations and defective safety equipment, according to court documents obtained by Us Weekly on Friday, January 2. 2XP LLC, Alterra Mountain Company, the American Motorcyclist Association, Mammoth Mountain Ski Area and Revelyst Adventure Sports are all listed as defendants. "Most of all, the Zingg family is seeking transparency and accountability wherever it is fair and just," attorney Kevin Biniazan said in a statement to USA Today. "If this legal action motivates safer operations of these races and equipment that these riders wear in a way that saves another family from enduring what the Zinggs have endured and will continue to endure, it will have been a success." 9-Year-Old Motocross Rider Killed in 'Freak Accident' at California Track Aidan died on June 28, 2025, following a mid-race accident during a Mammoth Motocross event in Mammoth Lakes, California. Outlet Dirtbikelover reported he went down in a corner of the track before being run over by multiple bikes. The race continued for two more laps as he lay unconscious before it was halted. "Aidan's fall would have been, and should have been, quickly observed and responded to by a caution flagger waving a yellow flag to warn other riders that Aidan was down on the track within a couple seconds of his fall," the complaint reads, alleging the corner where he fell was unmanned by a flagger at the time. Due to the race not being properly staffed, the complaint states, Aidan remained on the ground for up to four minutes while other riders continued to pass him. The complaint also alleged that Aidan's jersey and equipment showed signs of being struck by another rider and that his chest protector was punctured. 15-Year-Old Dirt Bike Star Amelia Kotze Dead After Race Crash Aidan was pronounced dead at Mammoth Hospital the day of the event.

Us reached out to Mammoth Lakes Police Department for comment at the time. "The things I could say. The stories I could tell. It's been a day and I feel like it's been a lifetime. My heart is completely broken," Aidan's sister, Alexandria, wrote via Instagram after his death. "You used to joke that I was so old and that I'd die first, I would always joke that you were crazy and you'd be the first. Now I'm sitting here wishing with everything that I am that you were right so I'd never have to live a day without you."
