Skender Pasha convoked the delegates of the Three Nations to a Diet at Gyulafehérvár. The Diet dethroned Gabriel on 21 October, urging him in a letter of farewell to accept the decision, and elected Bethlen prince two days later. According to the contemporaneous historian Máté Szepsi Lackó, András Géczi and Miklós Abaffy soon hatched a plot to murder Gabriel in Várad. They entered his room on 26 October 1613 and persuaded him to give them his sword, but did not attack the strong prince because he still had a dagger. The following day, Abaffy told Gabriel that the troops from Royal Hungary wanted to see him. After visiting Abaffy's army, Gabriel returned to Várad in a carriage. Horsemen suddenly attacked the carriage, forcing it to turn into a narrow street. Gabriel jumped out of the carriage, but was soon shot. He tried to resist at a willow tree near the Pece Stream, but dozens of Hajdús attacked and killed him. Hajdú infantry captain Balázs Nagy brought Gabriel's body first to Nagyecsed, and then to Nyírbátor. His body lay unburied in the crypt of the church in Nyírbátor, and he was ceremoniously buried at Bethlen's order only in 1628.
