A CBI court convicted dentist couple Rajesh and Nupur Talwar for the double murders of their daughter Aarushi and domestic help Hemraj. But some big questions still remain unanswered. If the crime scene was dressed up allegedly by parents, why were the bloodstains not removed? If golf clubs and scalpel were used in the murder, why weren't they seized? Also, if Hemraj was assaulted in Aarushi's room, why was no DNA proof available? NDTV discusses with a select panel of people who had followed the five-year-old case.
