One more angle to this case remains to be investigated. The murder could have been planned by someone who knew the family well, I mean it could be even some relative.... Just think, who would benefit from the death of Arushi...? Someone who knew that they had a child after a long gap of 5 years. Someone who maybe had an eye on the property....maybe that explains why Arushi was murdered first, Hemraj was the unfortunate witness victim. It also explains why they even tried to enter Talwars bedroom, but could not as it was locked. I dont think someone would simply murder a child bcos he was humiliated in front of others, while on his job. I think thats fairly routine, I guess. Here the whole point of bringing a khukri with a couple of people was to murder everyone in the family....why..? We have seen this before relatives closest to the family murdering for property. Is the killer still on the loose..having done half his job ? Maybe he knows after the doctors, there is no one to lay claim to the property...
