It was at this time that the kitchen knife which she was holding in her hand accidentally pierced the left side of his chest," the official said. Sandeep Turan, public relations officer of Gurugram police, said the post-mortem report was received on Wednesday. "Doctors mentioned...his heart was punctured," Turan said.
