I am not expressing my opinion with regards to Aarushi's murder case only from the context of the movie but after watching related videos,documentaries and write ups initially I too suspected the parents might be the convicts as we often hear about honour killing happening in our society however later getting deeper into the investigation part it is quite evident that the domestic help are the real convicts. I strongly believe that the parents where drugged so that they are unaware of what is happening in the next room of their house as the meeting would have been planned by Hemraj and his associates it's easy for him as he is the cook, there are so many cases being proved even left clueless, then the problem with the initial investigation who failed to do the procedure which led to the entire commotion in the case. May almighty help the parents to overcome their grief also let us pray that the guilty should be punished better late than never.
