The case been so messed up that even if the CBI does conclude something after investigation, it is unlikely that they will be convicted even by the lower court. But, I personally feel that the doctor could not have been involved in the murder even if he has knowledge of who committed the crime because it will be impossible of a first time criminal to withstand the sustained and persistent grilling in custody. Any normal mortal will break down except brainwashed islamic jehadis.
