Authorities searched the home of the pilot of the missing Malaysia Airlines plane that vanished on March 8.

At a news conference, Malaysian Prime Minister Najib Razak said investigators believe that the plane was deliberately diverted. He said communication devices on board were intentionally turned off and that the airliner’s last signal came about 7 ½ hours after takeoff.

The prime minister said the jetliner, which was carrying 239 people, could have ended up as far as Kazakhstan or deep in the southern Indian Ocean.

Authorities are now trying to trace the plane along both a northern and southern corridor. The north corridor stretches from the border of Kazakstan and Turkmenistan to northern Thailand, and the southern corridor goes from Indonesia to the southern Indian Ocean.

Zaharie Ahmad Shah is described as a 53-year-old married father of three and experienced pilot. His first officer, 27-year-old Fariq Abdul Hamid had 2,000 hours of flying experience, but had recently begun co-piloting the 777. He is also seen in photographs with two teenage girls, who he allowed into a plane’s cockpit back in 2011.
