Mykola Lisin wife Found Dead – The whistleblower at Burisma has been revealed to be the wife of former Burisma owner Mykola Lisin, who also passed away under mysterious circumstances during the years of the Obama administration when vice president Joe Biden and his son Hunter were active in Ukraine. The Burisma whistleblower’s identity has been confirmed by multiple sources.
