Onil considers Ariel to be a "monster," not a brother. "The monster is a goner," he said.
"I hope he rots in that jail," he said. "I don't even want them to take his life like that. I want him to suffer in that jail to the last extent. I don't care if they even feed him. What he has done to my life and my family's."
"I feel the same way," Pedro said. "I loved him so much. I loved him so much. As a matter of fact, the second time I seen him going in to use the toilet, when he finished, I was by the rails and he said 'I love you' and we, you know, we touched fists."
'I am a walking corpse'
Onil's and Pedro's bitterness is intensified by the embarrassment of having their mugshots released to the world as suspects in the horrifying crime.
"I haven't realized what is going on and why, why this happened," Onil said. "And my life is now, I feel I'm free, I'm out here now, but I'm not free. I'm still locked in somewhere."
He's haunted by nightmare each night, he said. "This has torn my heart apart. This has killed me. I am a walking corpse right now."
Pedro said that he, too, "is still locked up."
"I can't go nowhere because they think I'm a monster, too, and I'm not," he said. "And it just keeps going over and over in my head that people are just thinking that I did this."
The men are in hiding in an undisclosed location. They say rocks have been thrown through their windows, and they have been receiving death threats online.
"I don't want to be hunted down like a dog for a crime that I did not commit," Pedro Castro said. "I don't want to be locked up in my house because somebody out there is going to do harm to me. I want to be free like I was."
"Now, I feel trapped for what somebody else did, and it's a family member. ... They should not take it out on the family. Threats of burning up the houses, killing Pedro, that's not right. You already got your monster. Please give us our freedom. I want the world to know this."
