The challan submitted by the police to the trial court hearing Noor Mukadam's murder case suggests that her murder may have been avoided had the father of the man accused of beheading her called the police instead of helping his son.

This was reported by Geo News on Saturday after it reviewed a copy of the challan, i.e. the police investigation.

The challan says that Zahir Jaffer confessed to killing Noor and a DNA report confirmed she was raped.

Quoting from the challan, Geo reports Zahir telling the police that he forcibly locked Noor in a room, told his guard not to let anyone in or let her out. He also hid her mobile phone in another room.

The police retrieved the mobile several days after the murder.

The challan also states that Zahir informed Zakir Jaffer, his father, about killing Noor and his father told him not to panic, and he was sending his men to remove the body.

The police write in the challan that had Zakir told the police in time, Noor Mukadam's murder could have been avoided. The father helped his son, they say.

Jaffer is the prime suspect in the murder which shocked the nation when it occurred in his home in Islamabad on July 20.

Journalists and activists have used Twitter to continue to highlight the case and its progress.
