Every one seem to point their fingers at Arushi's Parents & I feel they cannot be removed from the suspect list too...But off late Ive noticed lots of crime news in Noida concerning servants, especially Nepali ones. Ex: Recently one nepali servant poisoned 4 member of a family & escaped with loot.
I myself have had bitter experience with nepali servants as I had caught them red handed stealing and cops had advised me not to hire them in future as they are not easy to trace.
Coming back to Arushi's case, the other angle which Im guessing is, Hemaraj must have been threatened from some people from his native who are thieves asking him to cooperate in looting the house. Thats y hemraj had earlier approached a NGO for help. There where 3 glasses of liquor in Hemraj room indicating that they all met first and Arushi got killed by them in the process. Hemraj must have panicked and they got him killed too. Coz its impossible for a person like Dr.Rajesh to single handedly kill Hemraj with out a struggle as there where no marks or indications in Dr.Rajesh body.
Another theory is, there must be some terrorist hideout or activity in colony which Hemraj must have come to know and when the NGO asked what was the problem he said he did not have proof. So he would have recorded it in his mobile and must have shared it with Arushi as well...thats y Mobiles were missing.
Im jus trying to see other possible theory..though the above theory looks weak..we cannot simply rule it out rite??
