The investigation into the missing Malaysia airliner is focusing on the crew and passengers on board Flight 370. 

Police in Kuala Lumpur are searching the home of the pilot of the missing jet. 

The search follows a news conference today by Malaysia's prime minister in which he said the passenger jet was deliberately taken off course. 

While stopping short of calling it a hijacking, the prime minister says the data they've uncovered is "consistent with deliberate action by someone on the plane."  

Malaysia Airlines Flight 370 vanished one week ago.
