Harris’ mother and stepfather say they are holding on to hope that he will be found.

“We don’t want to think about the worst, so right now I’m keeping myself very optimistic,” Harris’ mother Margaret Fernandez said. “I’m not really letting my mind wander anywhere else. It’s an ongoing investigation, so I’m very hopeful.”

“I feel that confident that we’re going to find him, that he’s going to come through, wherever he is,” stepfather Charles Taylor said. “I have to believe that. I have that kind of faith that we’re going to find him.”
