There's no way any of the family, family friends or the people who worked in that house (staff) will ever be indicted. The DA will find a way to blame it on some homeless huffer, crack head on bath salts.
Someone took the trouble to sit down and write a 2.5 page ransom note in the Ramseys' own house on their own note paper.
That has always pointed to an inside job by someone in the family.
I agree r3, the long ransom note is the most suspicious thing
Brevity may be the soul of wit, but in a well-penned ransom note, it smacks of indolence.
