Mr Sheikh and his wife Kausar Bi were allegedly abducted by the Gujarat Anti-Terrorism Squad from Hyderabad on their way to Sangli in Maharashtra.
Mr Sheikh was killed in an alleged fake encounter near Gandhinagar in November 2005, after which his wife disappeared and was believed to have been done to death.
Mr Prajapati, an aide of Sheikh and an eyewitness to the encounter, was allegedly killed by police at Chapri village in Gujarat's Banaskantha district in December 2006.
The Sohrabuddin killing case was transferred to Mumbai in September 2012 on the request of CBI for a fair trial.
In 2013, the Supreme Court had clubbed the alleged fake encounter cases of Mr Prajapati with that of Mr Sheikh.
