This is a shoddy piece unworthy of Pepe which would not be out of place on the page of a UK tabloid.
Are you telling me the following are points of information and not conjecture?

"Let’s start with the possible chain of events that may have led to the Crocus terror attack".

"The Budanov connection is betrayed by the modus operandi" (where,s the connection with Budanov?)

"There seem to be holes aplenty in the narrative concocted by the ragged bunch turned mass killers"

"Still, the FSB seems to have broken them all"

A potential handler has surfaced, named Abdullo Buriyev

"Yet the real person of interest here is not Tajik Ghafari but Chechen Abdul Hakim al-Shishani,"(says who?)

"Some of the four hapless Tajiks seem to have followed ideological/religious indoctrination on the internet dispensed by Wilayat Khorasan, or ISIS-K, in a chat room called Rahnamo ba Khuroson"

"Khurosoni is arguably a messenger between ISIS-K and the CIA."

"Yet in this case it seems it’s Khurosoni himself who has approved the 500 thousand ruble reward."

"After handler Buriyev relayed the instructions,"
(so the potential handler has now become the handler)

"Khurosoni may have been the ideological mastermind of Crocus"

"The FSB investigation is establishing a trail"
"The FSB investigation is also unveiling the standard modus operandi of online terror, everywhere"(ongoing,not concluded)

"
As for ISIS, everyone seriously following West Asia knows..."(so anyone who disagrees is dismissed as not serious?)

"The FSB is right in the middle of the painstaking process of cracking most, if not all ISIS-K-CIA/MI6 connections. Once it’s all established, there will be hell to pay."(so it,s clearly not established)

" the Crocus investigation seems to be leading exactly to where Moscow wants it:"
