Good summary! So there are 4 men in jail waiting for court and one fighting to keep his immunity not in jail yet.
My opinions only, no facts here:
A grand jury proceeding allows the presentation of hearsay evidence by the prosecution. What is hearsay? Think of "The Camping Episode" of Spongebob Squarepants. Hearsay is a friend of a friend of a friend of a friend of a friend of a friend, whose cousin said....... and so on. There is a darn good reason that so-called "evidence" in a grand jury proceeding is commonly NOT ADMISSIBLE in a real criminal trial. Frankly, using grand juries only, I am comfortable that the the suspect count in the Holly Bobo case could be increased even more.
I have followed criminal cases for about forty years. Simple female abduction cases that involve oodles of perpetrators and after-the-fact conspirators/witnesses are the exception and not the rule (but possible). More importantly, abduction cases that involve more than two perpetrators + independent witnesses + after-the-fact conspirators, are typically solved quickly. In the Holly Bobo case we are told that there are multiple kidnappers and after-the-fact conspirators/witnesses, yet it took three years to 'solve'.
On a side-note I just love The Musgrave Ritual with Jeremy Brett as Sherlock Holmes. The entire poetic ritual is wonderful, including these investigative parts:
'Whose was it?'
'His who is gone.'
'Who shall have it?'
'He who will come.'
AND
'What shall we give for it?'
'All that is ours.'
'Why should we give it?'
'For the sake of the trust.'
Quoting from 'The Adventure of the Naval Treaty' episode of Sherlock Holmes (Jeremy Brett), after picking up and examining a single red rose, Sherlock says something that makes me think of Holly Bobo: "There is nothing in which deduction is so necessary as in religion. It can be built up as an exact science by the reasoner. Our highest assurance of the goodness of Providence seems to me to rest in the flowers. All other things, our powers, our desires, our food, are all really necessary for our existence in the first instance. But this rose is an extra. Its smell and its color are an embellishment of life, not a condition of it. It is only goodness which gives extras, and so I say again that we have much to hope from the flowers."
In my sole opinion, there is one man we still need to hear from and one place we still need to look.
Sleuth On!
