In the hope of cracking an alleged murder, the city police on Wednesday demolished a house and evacuated another to dig the ground around it as they looked for the remains of a woman who went missing 34 years ago. At the far end of Qutubnagar Lane Number 3 in the Vatva area, an excavator dug through the floor of the house to reach an old drainage catchpit, called khaarkuva in local parlance. The attempt to exhume the remains of Farzana alias Shabnam, who was last seen alive in 1992, was taken up in the presence of an executive magistrate. With a green awning tied up on the roofs on either side, the forensic science laboratory (FSL) personnel poked through the mud with sticks and brooms, sifted through loose dust with a sieve, and collected possible fragments of human bone, teeth, and hair.…
