This was the first hit that Zainab’s family got after she went missing. The shop owner said he didn’t see her personally but he had CCTV cameras outside his shop. The family sat around holding their breath - eyes scanning the grainy footage. Some of the others were comforting them that they would find her in the footage and realize she was just lost. She would come home safe. But it fell silent. Nobody believed that anymore. On the screen, they saw 7-year-old Zainab in her pink coat walking hand in hand with a stranger. A strange man. He was not someone the family knew. He was Pakistan’s worst serial killer.
