A 72-year-old woman, María Yolanda Guerrero Medina, dies aboard a flight travelling from Chicago to Mexico, forcing the aircraft to make an emergency landing, according to multiple reports. She is on Volaris flight 7771 heading back to her home in Morelia, Mexico. The accounts say she becomes seriously ill during the trip, with her death occurring while still onboard. One report states she falls ill less than two hours after departure from Chicago, and that crew members respond by requesting an emergency landing. The plane ultimately diverts and lands due to the medical emergency. Authorities and the airline do not present differing public details in the provided accounts about the cause of death, the exact location of the emergency landing, or the condition of other passengers and crew. The reports focus on the timing of the illness and death, the flight route, and the resulting emergency procedure that leads to the aircraft landing before continuing its journey. The incident is treated as a sudden death on a commercial flight.
