My father, named Silas Costa (graduated at the Southwestern Baptist Seminary) at facebook passed away on the **th of May ****. Just a few days after that, my brother got inside his computer, changed his password, his phone number, and since then he is using his account, as he was alive. On the *nd of february he posted a message, showing clearly that he keeps the account active. My brother is blocked in my account, so he uses my father's account to spy on me. I haven't blocked my father's account, because he used to send me messages constantly, and many memories come up almost every day, related to his account and mine. *I was the one who created his account. I had his access code which was ****** at first, and when he was hospitalized, he gave me the new code as well. His email account is *****@***.com. I used to have the access to his email account as well, but my brother had changed the code of this email account as well. *My brother changed his telefone number to **(***)***-**** days after his death. And my dad didn't move from Brazil, so his phone number isn't a american one. *I was the heir contact elected by my father. But I don't know if my brother changed that feature. *I would like to know if I still am the heir contact? Do you have access to that information. *If I ask to turn that account as a memorial account, I would lose access to my father's profile, if my brother is the new heir contact? *Once again, I am deeply afraid to lose all the precious messages my father sent me. I have all the information proving my father's death. And if you look into his account You would see the information of his funeral near to the **th of May ****. *Please, help me!
