BETRAYAL OF PUBLIC, ESTE, MARITAL TRUST

Chief Justice Renato Corona wants to project the image that he is a loving husband to his wife, Cristina. The fact is, the Chief Justice has not only betrayed the public trust but most importantly, has betrayed his marital vow. 

If the Chief Justice is man enough, He should admit the fact that he has a long-standing romantic relationship with a gentle lady named EVA with whom the Chief Justice has two (2) illegitimate sons. EVA also hails from Batangas and had her education from Assumption College just like his wife Cristina who also graduated earlier from the same school.
For Chief Justice Renato C. Corona not to mention his children with EVA as if they do not exist at all, is the highest form of ignominy and immorality that he can commit not only against his legitimate wife and family but against his oath as the highest magistrate of the land.
An inquiry into his relationship with EVA and his illegitimate children in connection with the on-going impeachment trial becomes extremely necessary in the light of the properties given by the Chief Justice to them. EVA, who has previously undergone a heart bypass operation, is known not to have worked from the time she had this romantic liaison with the Chief Justice nor does she have any known business of her own and yet, EVA is luxuriously living in the United States, together with her two (2) illegitimate children with the good Chief Justice.

The SALN of CJ Corona does not indicate any such properties. 

And the reason for the frequent trips of CJ Corona to the United States, the latest of which was late last year, was to visit EVA and his children with her. That CJ Corona could afford to support the kind of luxurious lifestyle of EVA and her children in the U.S. is certainly for the Chief Justice to explain considering his small salary.

A simple investigation on the identity and circumstances of EVA can easily be done by a simple inquisition in Batangas as well as from the classmates, relatives and friends of EVA and of CJ Corona.
I know these facts because EVA is a relative of mine and it pains me immensely to see the Chief Justice professing his love for Cristina on nationwide television when he has confessed to my relative that he loves her far more than his wife. In fact, the Chief Justice made EVA believe that he was already separated from his wife Cristina. This probably explains why for the longest time, the Chief Justice has not reported in his SALN the fact of Cristina's working in government and the fact that Cristina has not signed the SALNs as his wife. 

Betrayal of public trust? This is a small matter than what the Chief Justice has done to his wife and family which constitutes the highest form of immoral act - BETRAYAL OF MARITAL TRUST.
Real name of CJ Corona's girlfriend - Eva Auria; She hails from Rosario, Batangas; She graduated from Assumption College (not from Maryknoll College) She has two (2) sons with CJ Corona who are now in their teens; She is residing now in the United States. CJ Corona's wife, Cristina, knows about the elicit relationship of her husband with Eva. To know more about the details on Eva, a simple investigation of Eva's background in Rosario Batangas and Assumption College would elicit the necessary informations. Eva has plenty of properties in the US. They keep secret the exact address. The bagman of CJ Corona (who facilitates the transfer of funds from Corona to Eva is "Abet" who is a relative by affinity of Eva, being married to a stepsister of Eva. (The wife of Abet has the same mother as Eva but different Fathers). The biggest delivery to Eva involves the bribe money given by the Aguirres of Banco Filipino.
If the bank accounts of CJ Corona and his wife are opened, it will not be a surprise to see a running balance of not less than P200M. The bribe from the owner of the previously closed alone was a whopping P200M. And most money went to Eva through the Assistance of Abet.
The sons of Corona carry the name of the mother. But CJ Corona has openly recognized Ate Eva's sons as his. A simple search at the NSO using "Renato C. Corona" would readily reveal this. For a time, when Eva was still in the Philippines, Renato and Eva lived as husband and wife. In fact, all our relatives in Rosario, Batangas and in the United States, knew the long-standing relationship. We all thought that Renato was already separated from Cristina. Some of Renato's relatives in Tanuan, Batangas where he hailed from, know about this relationship. Some friends of Renato have seen the 2 sons and have been their ninongs. All our relatives thought really that Renato will never deny his relationship with Ate Eva. Sana hindi nya gagawin iyon kasi kawawa sya at ang mga bata.
