He added that the team of experts who studied the case of poisoning concluded that it matched all the symptoms of chloropicrin. “All the specialists who contacted them, studied their photos and did personal examinations,” Gorev said. “What do we know: three representatives had almost identical symptoms – severe pain in the eyes, red spots around the eye, peeling skin.” The group “all said that this was not accidental, neither food poisoning, nor allergies,” he said. “It simply came to our notice then [chlorpicrin] and other military agents. “ Mr Gorev added: “The only downside to this hypothesis is that chloropicrin usually emits a very strong odor, which means that it is very difficult to give it away without being noticed. “But then one of the experts said that there were developments of this factor – odorless.” However, it may never be definitively known which poisoning agent was used, as this would require laboratory tests shortly after the incident. Mr Grosev said it was not possible for Mr Abramovich and the other victims to carry out in-depth investigations into the cause of the poisoning.
