On that night Hemraj had added few sleeping pills in Talwars drinks when they were first asleep , he wanted to loot Talwar's house , he called up other 3 guys and had a drink , then while starting the operation all of them went to arushi's room , but arushi did not take the drink , this forced them to change the plan , they gagged arushi first, but 3 of hemraj's friend wanted to rape her as well, they could have easily succeded to rape but hemraj and arushi prevented fiercely (Hemraj was not a bad guy , but he needed some money) , rest of 3 friends killed both arushi and hemraj and take away hemraj's body to the terrace.
