Scientific evidences should be acceptable in court. On basis of current findings, nothing can be ruled out at the moment. Its a terrific conspiracy. Talwars family's involvement cannot be ruled out due to the behaviour they have exhibited in full view of media & the haste for cremation of Ms. Aarushi & disposal of evidence at the earliest including perhaps bribing the UP Police & perhaps politicians. Ofcourse a good deal of people are involved in this conspiracy ranging from the doctor parents, to servants to the close friends of the doctors. And the fear of the conspirator is yet forcing them to be tightlipped. Who is this Don?. As per law only the executers of the crime will be punished. Eliminated persons definitely knew some information, so serious & critical, to the business & future of the Talwars & other influential friends & The MYSTERIOUS DON?. However Doctors do have easier & slower methods for elimination, than going for murders. Was the murder so urgent? Why was Ms. Aarushi given a camera as a birthday gift on the day of murder? Was it to fulfill her last wish by her parents?. Its definitely a MYSTERY & the crime is classified as an organised conspiracy. IT should be investigated in full. Right now it can be only said that all the people are just in fear of the DON-the mastermind, who may have by now even escasped overseas, due to the time elapsed & delay in the investigation.
