From the moment Alexander VI knew this crime had been committed, and assumed responsibility for its motives and consequences, and pardoned the murderer, he became morally accessory after the fact, and fell himself under the power of his terrible son.

From that time on, every act of his was intended to further Caesar's fiendish ambition.
None of the records of the day say that Don Giovanni's consort was in Rome when this tragedy occurred.

We are therefore forced to assume that she was not there when her husband was murdered.

It is much more likely that she had not left Spain, and that she was living with her two little children in Gandia or Valencia, where she received the dreadful news in a letter written by Alexander to his sister Dona Beatrice Boria y Arenos.

This is rendered probable by the court records of Valencia.
September 27, 1497, Dona Maria Enriquez appeared before the tribunal of the governor of the kingdom of Valencia, Don Luis de Cabaineles, and claimed the estate, including the duchy of Gandia and the Neapolitan fiefs of Suessa, Teano, Carinola, and Montefoscolo, for Don Giovanni's eldest son, a child of three years.
