On December 24, 2018, a helicopter carrying Martha Érika Alonso Hidalgo, the newly elected governor of the Mexican state of Puebla, and her husband, senator and former governor Rafael Moreno Valle Rosas, crashed on a hill in Coronango near the city of Puebla. All five people on board the helicopter were killed in the crash: Alonso, Moreno, the two pilots, Captain Roberto Coppe Obregón and Captain Marco Antonio Tavera Romero, and an assistant to the senator. Alonso was 10 days into her term as governor at that time of the crash. The accident investigation found a preexisting problem with a stability system on the helicopter.
