Investigative actions with this individual are underway… In order to organize this cynical plan, Russian security services recruited a Ukrainian national G, who was tasked with finding perpetrators of this cynical murder," Hrytsak said, adding that individual G was paid $40,000.
"The perpetrator was a highly professional killer, but he himself could not have planned this crime," Knyazev said.
