The Strange Death of Denys Kiryeyev: Hours before Russia first sent troops into Ukraine, Mr. Kiryeyev warned of Moscow’s plan to capture Kyiv. Days later, he was killed by [Ukrainian] security agents.

“If it were not for Mr. Kiryeyev, most likely Kyiv would have been taken,” the general said.

He used his Russian connections to save Kyiv. He wanted to negotiate an early end to the war. Then the SBU summarily executed him claiming he was a Russian spy.
