If I was 25 years old again, and my baby disappeared in similar circumstances, and LE shared with me that they were positive they had the perpetrator in custody, and they shared with me WHY they believed so...
And if, because of a family link to another high profile child missing case, going public might do more harm to the case against him, especially, if I was CONVINCED he did it...
I wouldn't go public either. I would cooperate with LE, stay low so the media focus stays on LE's statments only, and not give the media, or his defense side ANY room to pin it on me or my family.
If I felt there was no point in going public because the perpetrator is already caught...I wouldn't do it. I'm camera shy, I don't handle unfamiliar people questioning me very well at all, and I would be very afraid of saying too much, or being misinterpreted. Especially if I were sure my child was dead, I just wouldn't want to be anywhere near media, cameras, and drama. I would be too busy taking care of my daughter while grieving the loss of my baby, and I wouldn't care what anyone thought. But that's just me...
I am bothered by Lonna not being interviewed yet, but I can see a scenario where she may not want to talk or perhaps she has been advised that it is the best thing she could do for now.
Just a thought and JMO
