Digital Sleuths ID Third Man in Novichok Case
Investigative site Bellingcat has named Denis Sergeev as the third suspect in the nerve agent poisoning of Russian ex-spy Sergei Skripal and his daughter in the U.K. last March. It also linked Sergeev — a high-ranking Russian intelligence officer sometimes known as Sergey Fedotov — to the 2015 poisoning of a Bulgarian arms trader and his son.
What are authorities doing? British and Bulgarian officials are conducting a joint probe into the matter, though it may prove challenging: One investigator says Sergeev is the trickiest spy they’ve ever followed.
