Muhamamd Afzal, brother of one of the convicted men, has claimed that four women have been murdered.
Four women and two men had been sentenced to death in Kohistan for singing and dancing at a wedding.
Clerics had issued a decree after a mobile phone video emerged of the six enjoying in a remote village in the mountainous district of Kohistan.
It was decided that the men will be killed first, but they have run away.
Meanwhile, DPO Tahir Rehman has said that he has no information about the killing of four women.
