According to the initial statement by the hospital, Aguayo died from a cervical spine trauma, reportedly as a result of the dropkick by Mysterio Jr. that propelled him forward to the ring ropes, causing severe whiplash trauma that snapped his neck. The cause of death was later determined as cardiac arrest, due to a cervical stroke caused by three fractured vertebrae. Autopsy results showed that Aguayo Jr. broke his C1, C2, and C3 vertebrae. The coroner stated that the fractures took place at two different moments of impact and that Aguayo died almost instantly. Aguayo Jr. was not immediately attended to by a physician and was actually taken from the ring on a piece of plywood instead of a stretcher, which led to some criticism of the event organizers. However, the coroner stated that it made no difference. The Tijuana wrestling commission later explained that the doctor was backstage, attending to two other injuries that happened during the show. One of those injuries was a spinal injury and they did not want to remove that wrestler from the stretcher he was on, which was why they used the plywood to move Aguayo from the ring. The doctors worked on resuscitating Aguayo for over an hour before declaring him dead. On March 21, the attorney general for Baja California conducted an investigation into Aguayo's death but no criminal charges were filed. Aguayo Jr. was buried in Guadalajara on March 23 with Konnan and Rey Mysterio Jr. serving as pallbearers. After his death, the "Comisión de Deporte del Senado del México" (The Commission of Sport of the Mexican Senate) presented the initiative "Ley para la Seguridad del Deporte en el País" (Law for the Safety of Sport in the Country").
