It's simple, if the compounder Krishna and Durrain's domestic help Rajkumar are the real culprits and they had done it under the influence of alchohal, they should have FLEED IMMEDIATELY after the incident, NO DOUBT ABOUT IT. No one can imagine that a compunder killed his employer's daughter and still attending his duties with out fear.
THEY DIDN'T FLEE AFTER THE MURDER BECAUSE, DR. TALWAR'S ASKED THEM TO KILL AARUSHI AND HEMRAJ?
IT IS 100% TRUE THAT CBI IS BUSY IN FABRICATING A STORY FOR UNKNOWN REASONS...THEY ARE NOT READY TO REVEAL EVEN AN INCH OF THE TRUTH....
