For one Pakistani mother, sunburn signals her desperation to find her son.
Zarjan Atta rode rickshaws and buses for four days on desert roads, deepening and reddening her brown skin, as she traveled from her village to Karachi, Pakistan's southern port mega-city.
That's where her son Nawaz, 23, was living with relatives and studying at Karachi University. Her relatives say armed men dragged him from their flat on Oct. 28. They were in civilian clothes.
They pushed the women and children into a room. They warned: If you speak, you'll be next.
