Over 200 people have been questioned in connection with the mysterious deaths of 11 members of the Chundawat family in north Delhi's Burari, even as the police are certain that it was a case of "mass suicide", said a senior police officer.
The police are awaiting the final postmortem report even though initial findings suggested that the 11 died of hanging, they added.
After receiving the report, the police will go for a psychological autopsy of the deceased to ascertain what prompted them for replicating "badh tapasya", a banyan-tree like formation.
One of the deceased, 33-year-old Priyanka Bhatia's fiance was questioned again and he denied knowing anything about the family indulging in certain kinds of rituals.
He was questioned for close to three hours today, sources said.
Ten of the 11 members of the family were found hanging from an iron-mesh in the ceiling earlier this month, while the body of 77-year-old Narayan Devi, the head of the family, was lying on the floor in another room.
Daughter of Devi's daughter Pratibha, Priyanka, who had mangal dosh, was engaged last month and would have married by 2018 end, police said.
Last Wednesday, the police had recovered CCTV footage that showed some members bringing stools and wires that were used for their hanging. They had also found 11 diaries which had "psychological musings" and things about attaining "road to God".
