I found it...
As the story goes Pedro went out for a quick defeat of the latest uprising in the Mayan conquest. In doing so he left his lovely Beatriz and their 5 year old daughter at home to mind the palace. Due to a landslide, he never returned alive. It was within days after his death that the Doña Beatriz seized control of the government and was in the Cathedral of the Palace with her attendants and her daughter. There was a catastrophic storm combined with an earthquake resulting in the lake that was at the top of Volcano Agua falling down to the bottom of Volcano Agua destroying the Cathedral of the Palace and those inside, as well as the majority of the city.
