A police spokesperson said the DNA profile of the corpse found in a remote Latvian forest matched those taken from Rozhetskin’s blood-stained holiday villa in the seaside resort Jurmala, where he was last seen four years ago.
As a shareholder in investment company Blue Bull, Rozhetskin also backed the founders of City A.M., Jens Torpe and Lawson Muncaster, when they launched the paper, and he joined the board as a non-executive director from the start in 2005.
After a four-year search, authorities discovered the corpse earlier this month in a forest near Tukums, with Rozhetskin's credit card.
Police spokeswoman Sigita Pildava said: "Based on above mentioned the investigation has reasonable grounds for assumption that the found unidentified corpse is related with the crime which had happened in Rozhetskin's place of residence shortly before his disappearance."
She said they would be carrying out further tests to compare the DNA samples with that of Rozhetskin’s relatives.
