Tashfeen Malik's path to accused mass killer in California began in a small city on the Indus River in Pakistan's Punjab province.
It was from here, when she was a toddler, that she moved with her father, Gulzar, 25 years ago to Saudi Arabia, where he became more deeply religious, more conservative and more hard-line, according to a family member.
A picture slowly emerged Friday of the role and possible motivations of 27-year-old Malik in this week's killing of 14 people in California, including her apparent pledge of allegiance to the leader of the Islamic State militant group, according to U.S. officials.
