He said Afzal Guru's wife Tabassum was in a state of deep shock. "All that she and the rest of the family now want is his body," he said.
Home Secretary R.K. Singh, however, asserted that the family was informed about the hanging.

Afzal Guru, who leaves behind a son in Class 8 and who is believed to have given up his MBBS course in the first year, had wanted an end to the "living death".
