All of the attention on the parents may have impeded the investigation. (per Greta)
that would have been avoided if the parents took LDT's and let Burke get interviewed alone....
Marc Klaus had it right....give everything to the police and then they can move on.....
until the parents were fully dismissed as suspects, the cops can not move on....as in the Westerfield case.....parents had to go thru the gauntlet so to speak for the cops to look in other directions.....
