They came up with pretty much everything except a film of them planting the poison or a signed confession, but the Russians clearly have no plans to extradite them or even charge them with anything judging by how Putin is describing the situation.
British officials have said the men were agents of Russian military intelligence dispatched to kill Sergei Skripal, a Russian ex-spy who had given information to the British.
British authorities last week charged two Russian men, identified as Alexander Petrov and Ruslan Boshirov, with attempted murder over the botched poisoning earlier this year, which used the military-grade nerve agent novichok.
Russian state TV channel Rossiya-24 said the suspect named as Alexander Petrov would maybe speak next week.
Alexander Petrov and Ruslan Boshirov (who have to be the two Russians with the most Russian names ever) were accused of the Sergei Skripal assassination attempt.
VLADIVOSTOK, Russia-President Vladimir Putin said he knows the identities of the two Russians accused by the United Kingdom of poisoning a former Russian spy in England, urging them to come forward and tell their story.
In an address to the Easter Economic Forum in Vladivostok, he said: 'Of course, we looked who these people are.
'I hope that they will emerge (in public) themselves and tell about themselves. "There is nothing particularly criminal there, I assure you", he said. "We'll see in the near future", he added.
The Skripals survived, as did a police officer, Nick Bailey, who became sick after responding to the scene.
Rowley gave it to his girlfriend, Dawn Sturgess, who later died.
He said the government had exposed them as GRU operatives - and that is what they are. The Brits have leveled charges against them, while not having much in the way of expectations that they'll ever get their hands on them.
British Home Secretary Sajid Javid said on September 9 that Britain will catch the two men and bring them to prosecution if they ever step out of Russian Federation.
British prosecutors issued a warrant for the suspects' arrest last week.
Russian Federation adamantly denies involvement in the poisoning, which had added to severe strains in ties between Russian Federation and the West.
In July, Mr Rowley came across the poison, which had been concealed inside a perfume bottle and left in a charity bin.
