The dissident journalist was murdered at Saudi Arabia's embassy in Turkey after he entered on October 2.
Widespread reports suggest his body was dismembered, with one report saying his fingers were sent back as to Saudi Arabian crown prince as a ghoulish trophy.
The oil-rich country have denied any direct involvement with the gruesome death and said it was the work of 'rogue agents'.
Dogu Perincek, leader of Turkey's Rodina party, claimed in an interview his body parts were discovered in Istanbul during forensic searches.
He claimed the remains had been found in the garden of the Saudi consul general’s home.
A ‘highly placed’ source told Sky News the writer had been “cut up” and his face “disfigured.”

It is claimed he was brutally tortured and murdered by a 15-strong hit squad operating with instruction from high levels of Saudi government.
It is also alleged he was dismembered and his body parts were removed from the building as part of a cover-up before the hit squad left the country on private jets.
He had arrived to get documents for his upcoming marriage.
His Turkish fiancee, Hatice Cengiz, was waiting for him outside and reported him missing after he failed to emerge.
