The defence team then went on to tell the court that on the night of the murder, it was likely that Hemraj allowed his friends into the Talwar's home after the couple had gone to sleep.  The group then had drinks on the terrace, and some of the outsiders then went inside the home and tried to attack Aarushi in her room. The Talwars' lawyers say she was killed for resisting the assault.  When the attackers went back to the roof and reported what had happened, they say, Hemraj may have tried to hit them.  In retaliation, they allege, he was killed. The Talwars' argue that both victims were killed using a sharp knife or "Khukri."
