Searching for the Lost
William, Sabrina's older brother, was 8 when she was abducted. Her sister, Monica, was 4. "I remember I used to go into her room sometimes right when I woke up and just look at her," Monica says. "That's pretty much the extent of what I remember from her, but I did it every day, so I remember it. I definitely miss her a lot."
The Aisenbergs believe vital information could come from anywhere. "Somebody who knows the family she's with right now could see your show today and say, 'Wow, I heard the story of how they got this child and when you look at this story, that story doesn't add up,'" Marlene says.
