All on board missing Malaysia jet now under scrutiny, officials say

Like an Agatha Christie whodunit, the investigation into the disappearance of Malaysia Airlines flight 370 is now focusing on a finite circle of suspects _ the 227 passengers and 12 crew members of the missing plane.

While reluctant to call it a hijacking, Malaysian officials now say they believe somebody inside the plane with expertise in the navigational and communications systems of the Boeing 777 diverted it from its Kuala Lumpur-to-Beijing flight path.
