Authorities on lookout for partner of gunman

French woman arrived in Turkey week before hostage crisis, thought to have gone to Syria

A crossbow in her hands and covered head-to-toe in a black Islamic headwear and robe that leaves only her eyes visible-that is the image now circulating of France's most-wanted woman: Hayat Boumeddiene.

The 26-year-old is the partner of Amedy Coulibaly, one of the three gunmen shot dead by police after three days of high drama in France.
