DNA tests results have confirmed that the same culprit carried out the horrific rapes and murders of eight children in Kasur, including seven-year-old Zainab Amin, police said on Friday.
"One thing that is very clear [from DNA tests] is that in seven previous cases, and this is the eighth case, in which the same culprit carried out these horrific crimes," Inspector-General of Punjab police (IGP) Arif Nawaz Khan told Geo News.
He said that police has not been able to match that DNA to any of the suspects interrogated so far.
"We investigated almost 227 people, of which we narrowed down 67 suspects and carried out their DNA tests. But none of these results match those of the culprit," said the provincial police chief.
