Police in Abu Dhabi are searching for a suspect who killed an American woman in an upscale mall, but they don't have much to go on: The black-clad person captured on security footage had his or her face covered with a niqab. Police say the 37-year-old woman, a kindergarten teacher with 11-year-old twin sons, was stabbed during an argument in a women's bathroom on Monday and died in a hospital from her injuries, the Daily Mail reports.
Witnesses tell the National that they heard two women arguing. "Women go to the bathroom together and gossip, talk, and argue all the time," a mall restaurant worker says. "But then I heard one of them threatening the other, saying, 'Sit down or I'll kill you.'" A police spokesman says investigators are still trying to determine a motive and will "spare no effort in order to unveil this heinous crime and bring the culprit to justice." The woman's children are being cared for by authorities until her ex-husband arrives from overseas, police say.
