If your only argument is that why would a person lie at death bed (even after seeing her earlier statements) then you are also not sure about that death bed statement and just seeking validation to your belief..

Accused can't be hanged based on that statement, not even in an ideal world. Also everyone except the family of victim is telling same story. So many people cant have similar statements, atleast 4 person mentioned she went to police station on the bike (can't with a broken spine)

Everyone saw her and her family's statement that nothing happened except strangulation. Baaki enquiry kara lo jisse man chahe if they are find guilty or gangrape and murder then hang them.
