I think Aarushi somehow got involved with sexual relation.She had both of them Hemraj and Krishna.Later on she liked Hemraj and Krishna got angry and informed Aarushi's father.They both decided to kill aarushi.One way Krishna's jealous win over by killing Hemraj and Aarushi's father avoided the shame.Both of them are involved for sure.Poor Aarushi's mother she does not have guts.It is a typical Delhi type case where men controls everything.Eat to shit.
