"I want him to suffer in that jail," Onil Castro told CNN. "I don't care if they even feed him."
The two brothers, who were arrested last Monday in connection with the kidnappings, were initially believed to be complicit with Ariel. By Thursday however, they had been cleared of all charges, and released from police custody.
Onil recalled what their brother said when they ran into each other in jail:
"When he walked past me, he goes, 'Onil, you're never going to see me again. I love you bro.' And that was it. And he put his fist up for a bump."
Pedro also elaborated on how the Castro's knew Feliz DeJesus, the father of Gina DeJesus.
"We've know this man for a long time, and you got his daughter? And you go around like it's nothing. You even went to the vigils. You put out posters, and you gave her mama a hug, and you had her captive?"
"This has torn my world apart," Onil said. "This has killed me. I'm a walking corpse right now."
