Under new anti-"honor killing" laws that took effect in October , neither Parveen or her son will be eligible for pardon even if another family member forgives them for the crime.

Previously, murderers were able to walk free in many instances, creating what critics characterized as a culture of impunity. Now, a killer will face a minimum sentence of 25 years in jail.
