The night before Khadiza Sultana left for Syria she was dancing in her teenage bedroom. It was a Monday during the February school vacation. Her niece and close friend, at 13 only three years younger than Khadiza, had come for a sleepover. The two girls wore matching pajamas and giggled as they gyrated in unison to the beat.
Khadiza offered her niece her room that night and shared a bed with her mother. She was a devoted daughter, particularly since her father had died.
The scene in her bedroom, saved on the niece's cellphone on Feb. 16 and replayed dozens of times by Khadiza's relatives since, shows the girl they thought they knew: joyful, sociable, funny and kind.
