No. I think it's so far removed fron Putin that the link to him will never be proved.
There is no such a person as an ex KGB/FSB agent.
It's like the line in 'Hotel California', 'You can check out any time you like but you can never leave'.
The murder (because that's what it was) of Stephen Curtis, a lawyer who became involved in the cat's cradle of Russian intrigue around the oil business Gazprom and the incarceration of Boris Berezovsky who (among others) sought sanctuary here, could never be proved, despite years of investigations.
His rented helicopter, taking him from Battersea heliport to his home on Portland, mysteriously exploded mid-air, killing both him and his usual pilot.
Efforts to untangle the financials in the case were fruitless...as you'd expect. He was known as 'The man who knew too much' as not even the Oligarchs who placed their trust in him, knew exactly where their money went or the routes by which it was sent.
The knowledge died with him.
I believe that Putin never actually orders any 'disappearance', I think it's an unspoken 'given' and that thise who know him best have no need of words to do his bidding.
Trump, IMO is an outspoken fool at times but enjoys the limelight, opening mouth before engaging brain, however, I do think that he's smarter than many give him credit for.
This is only my opinion and, depending on where you stand, the same view can look very different.
