The excessively superstitious couple from Andhra Pradesh, who recently killed their two adult daughters in Madanapalle in Chittoor district, still believes that their daughters will come back to life.

The couple, V. Purushotam Naidu, a lecturer at the government women's degree college, and his wife V. Padmaja, a mathematics teacher, responded to police queries in a relatively sane manner on Wednesday, barring chants about Lord Shiva in between.
