Parveen Rehman, a media-shy social worker who devoted her life to the development of the impoverished neighbourhoods across the country, was gunned down near her office in Karachi's Orangi Town on March 13, 2013.
The very next day, police killed a Taliban operative named Qari Bilal in an encounter and claimed he was the murderer, resulting in a closure of the case.
The Supreme Court of Pakistan in April 2014 ordered authorities to conduct a fresh probe into Parveen Rehman's murder after a judicial inquiry had revealed that police officers had manipulated the investigation.
