The FBI mission is not simply to figure out who commited a particular crime, they must build a case that will support a conviction. Confidently identifying who committed a crime does not help the prosecutor if the FBI cannot build a case they can win in court. A win is a conviction. It can be accomplished by trying a case or negotiation of a plea bargain. 

I have seen investigations in which law enforcement agencies had a really good idea who committed the crime but the active investigation was eventually terminated when they were unable to gather enough evidence to support a successful prosecution.

This brings up an interesting point that many may not understand. The FBI essentially serves the US Attorney in this case. The FBI does not investigate for their own purposes. If the US Attorney says we are not going to prosecute this case for whatever reason the FBI is compelled to close the case.

With that said, The FBI received an unknown piece of material evidence in 2010 that was submitted to Quantico. The results of the Quantico analysis were received by the FBI in early 2016. These results were the straw that broke the camel's back and caused the US Attorney to close the case. What was this evidence?

Could some of those tie particles be from cleaning the sunglasses with the tie.. one of the stews thought they looked like prescription sunglasses.

Optical coatings SUNGLASSES.. 1968

The layers 14, 16 may consist of the oxides of titanium, lead or bismuth or zinc sulphide, and the layer 18 may be constituted by Ni, Fe, Cr, Ti, Al, La, In, Sn, Pb, Ta, W, Co, Mo, Os, Ir, Pt, Yt, Zr, Ni, Zn, Cd, V, Hf, Re, Tl, Si, Ge, As, Sb, or Te or an alloy or any two or more thereof.

metals such as sodium, potassium and calcium. Specifically, titanium, iron and chromium are preferred in this reflection-reducing layer, however aluminum, lanthanum, indium, tin, lead, tantalum, tungsten, cobalt, molybdenum, osmium, iridium, platinum, yttrium, zirconium, niobium, zinc, cadmium, vanadium, hafnium, rhenium and thallium can also be used in this reflection-reducing layer. Semi-metals (i.e. elements which possess metallic and non-metallic properties) such as silicon, germanium, arsenic, antimony and tellurium have also been found to be useful in this layer.

I don't recall, does it state that Cooper used his left hand to go into the briefcase? if so, the odds are that he's left handed...

Mitchell's 302 said left hand in sack and briefcase?  others said right hand case next to him.. another said held case on side with left hand and right hand in case when he went to the lav..

reformatting to be a standard 6x9 paperback, so Sheridan will be proud.

ran into this interesting paragraph:

Back upstairs, Grecco put on a white dress shirt, black slacks and a pair of oxfords. He was a civilian and he didn't want any mistake about it. If others wanted to wear army fatigues, go on patrol with the troops, and ambush Viet Cong, that was their business.

I suppose Filipinos were in Sheridan's work environment in Vietnam.
I had been wondering when/where Sheridan met his 2nd wife.
I'm guessing in Vietnam around '69, maybe '68.

Here, he talks about a Filipino radio operator in the office.

The radio operator's desk was only a couple meters from Grecco's desk. Tony Sanchez, a Filipino, sat all day dispatching coded messages to the regional office in Can Tho. "Papa Alpha, This is Bravo Whiskey. Come in Papa Alpha," he would shout over and over again into his microphone. Grecco was surprised at how oblivious everyone was to the noise or at least they seemed to be. Vince could hardly re-strain himself. At times it was all he could do to keep from smashing the radio to bits. What were all those messages? Just how confidential were they? Were they all that urgent? He was sure they weren't. 

Interesting post on whether some tie particles came from wiping coated sunglass lenses.

Having seen the man and his garb on several occasions, I can not see Sheridan Peterson investing in expensive sunglasses with exotic optical coatings.

Sheridan and I take our sunglasses advice from ZZ Top.

When you get up in the morning and the light is hurt your head
The first thing you do when you get up out of bed
Is hit that streets a-runnin' and try to beat the masses
And go get yourself some cheap sunglasses
Oh yeah, oh yeah, oh yeah
Spied a little thing and I followed her all night
In a funky fine Levis and her sweater's kind of tight
She had a west coast strut that was as sweet as molasses
But what really knocked me out was her cheap sunglasses
Oh yeah, oh yeah, oh yeah
Now go out and get yourself some big black frames
With the glass so dark they won't even know your name
And the choice is up to you cause they come in two classes
Rhinestone shades or cheap sunglasses
Oh yeah, oh yeah, oh yeah.

EU: How did you determine this?
What would take 6 years for Quantico to process?
It sounds like they're worse than most people who post on this forum...I mean you've only got 4 years on them.

Ayn Dietrich-Williams spoke to this in an article at the time the case was closed.
