Woman at centre of California shooting remains a mystery

The Pakistani woman who joined her US-born husband in killing 14 people in a commando-style assault on his co-workers in California is at the centre of a massive FBI terrorism investigation, yet she remains shrouded in mystery.
The FBI acknowledges knowing little about Tashfeen Malik. Those who attended mosque with her husband, Syed Farook, say they know nearly nothing about her. Even Farook’s mother, who lived with the couple and their six-month-old daughter, knows little, according to lawyers for Farook’s family.
