Pakistani tycoon Zakir Jaffer's son Zahir has been sentenced to death for raping and beheading 27-year-old woman Noor Mukadam after she rejected his marriage proposal last year. The 30-year-old had held her hostage at his home in Islamabad and tortured her for two days before killing her, according to reports. Noor, a former diplomat's daughter, was his childhood friend.
