A nurse who lived near Jodhpur, Bhanwari had a penchant for affairs with political leaders. Two politicians including a former minister have been arrested for her murder. She disappeared from near her home in September.
The CBI took two of the hired hitmen who allegedly played a key role in the murder and recreated the scene of the crime near the canal where the nurse's body was set on fire.
The remains were then scattered into the water in the Rajiv Gandhi Lift Canal near the village of Jaloda, 100 kilometres from Jodhpur. Divers in the canal, to which water supply has been stopped to enable investigators to find evidence, found the bat that was used to smash her skull.
Both Mr Singh and Mr Maderna are from the Congress party. Mr Singh has been put through DNA tests to determine if he fathered Bhanwari's youngest child.
A Jodhpur court today extended the judicial custody of Mr Maderna and Paras Ram Vishnoi, brother of Malkhan Singh, till January 20.
