Five days after her disappearance, she was found raped, dead and buried in a garbage dump on Jan 9 near the Kashmir Chowk.
According to the initial post-mortem report, the minor was strangled to death after being raped multiple times.
As per the autopsy, the girl had marks of torture on nose, neck, and other parts of the body, the report said.
Hundreds of enraged protestors clashed with the police in Kasur last week over this incident.
The Punjab administration had then said that six personnel, including four policemen and two civil defence personnel, were arrested for allegedly opening fire at the mob.
Kasur made international headlines in 2015 when a gang of paedophiles running a child sex ring was busted.
The court observed that had the police been serious since 2015, so many cases would not have occurred.(ANI)
