NTSB are doing that lab work right now in Washington D.C.
You seem to not know the meaning of suspect, so here is the definition:

sus·pect
verb
3rd person present: suspects
/səˈspek(t)/
1.
have an idea or impression of the existence, presence, or truth of (something) without certain proof.
"if you suspect a gas leak, do not turn on an electric light"
Suspicion doesn't mean baseless hypothesis, e.g. "Mars is an orange." The NTSB would never say (and has not said, as you've conceded) it "suspects" the "bolts were never screwed in."
Were there a lack of marks where the bolts should have exerted clamping force, there would be basis for suspicion. That isn't proof. But it's more than a hypothesis.
I mean you can believe what you want but NTSB literally had a guy at a podium say into the mic last night that there is so far no evidence "the bolts were ever there", around the 17-18 minute mark if you have nothing better to do. Good luck with your investments.

Where are you getting this? Crookshanks said the NTSB had "not yet recovered the four bolts" and "have not determined if they existed there" [1].
Your source, for which I'm genuinely curious, is categorically false in suggesting the NTSB "suspects" the bolts were never there, or that Crookshanks said "there is so far no evidence 'the bolts were ever there'". (The latter being particularly reprehensible, given it involves materially misquoting an aircraft investigator.)
