A Pakistani court has sentenced a suspected serial killer to death for the rape and murder of seven-year-old Zainab Ansari. A prosecutor said the convicted killer, 24-year-old Imran Ali, would be tried on more cases later. Ali's DNA was matched to cases involving seven other girls, out of 12 similar incidents that took place in a year. Zainab's parents told reporters they were satisfied with the sentence, but wanted to see Ali hanged publicly.
