Addressing a press conference in Lahore, Shehbaz said, "His name is Mohammad Imran. He is a 24-year-old resident of Kasur."
The Punjab chief minister also called Imran a 'serial killer'.
The minor's father and Punjab Law Minister Rana Sanaullah were also present at the press conference, Geo News reported.
Shehbaz added, "He [Imran] admitted to all his crimes in a polygraph test that was conducted after his DNA matched the sample. I am most thankful to the forensic lab who profiled 1,150 DNAs to find the real killer."
The Punjab Chief Minister said that he had been informed about the DNA profiling test earlier and the subsequent match with Imran. He, however, waited for the results to get confirmed by the forensic lab.
"I requested them [officials] to not discuss it after the match was found. I visited [the lab] next day after morning prayers and was told that it was a 100 percent match," continued Shehbaz.
Shehbaz had promised the minor's parents to bring her daughter to justice as soon as possible and that the culprit would be prosecuted in an anti-terrorism court with all legal formalities.
He also requested the chief justice of the Lahore High Court to ensure that the hearing of the case to is heard day and night, without any delay.
