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.

However, in a Facebook post of the latest press statement, the Malaysian government asked the public to refrain from jumping to conclusions over the police investigation into the disappearance. The statement said it was normal procedure to investigate crew, passengers and engineers in the circumstances.

While reluctant to call it a hijacking, earlier today Malaysian officials said 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.

"In view of this latest development, Malaysian authorities have refocused their investigation into the crew and passengers on board," Malaysian Prime Minister Najib Razak said at a news conference Saturday in Kuala Lumpur.

Among those who are coming under investigation are pilot Zaharie Ahmad Shah. The 53-year-old Zaharie is one of the airline's most seasoned pilots, described by Malaysian newspapers as an "aviation geek" who owned a flight simulator at home and flew remote-control airplanes and helicopters as a hobby.

Co-pilot Fariq Abdul Hamid, 27, with the airline since 2007, has already been the subject of speculation because of an incident in 2011 in which he invited two young South Africa women into the cockpit during a flight, and according to the women, flirted, smoked cigarettes and posed for photographs.

Since the airliner vanished a week ago, investigators have been looking at the backgrounds of two passengers traveling on stolen passports. Both were young Iranian men. Pouria Nour Mohammed Mehrdad, 19, was booked through to Frankfurt and his mother was waiting for him there. Delavar Seyed Mohammed Reza, 29, boarded the flight together with Mehrdad, according to CCTV footage later made public, but had been booked to Copenhagen.

Investigators have said the two had no known links to terror organisations and appeared to be economic migrants trying to reach Western Europe.

Now, the rest of those on the flight are coming under scrutiny, transformed from victims to potential suspects. The largest number of passengers, 159, were Chinese nationals and most of the rest were Malaysians, with a few Ukrainians, Indians, Indonesians, Australians and two New Zealanders.

Among the Chinese were a group of artists and calligraphers returning home from an exhibition in Malaysia celebrating the "Chinese Dream." One of them was Maimaitijiang Abula, a 35-year-old ethnic Uighur from Kashgar in western China. He's been singled out for special attention by the Malaysian press because of the fears of violence surrounding the Uighur separatist movement in China. Some reports incorrectly identified him as an electrical engineer.

"It is important to profile all the passengers and crew. All the countries whose nationals were on that flight have to participate in the investigation so that they can narrow it down to who is responsible," said Rohan Gunaratna, a Singapore-based terrorism expert. "It is very likely that more than one person was responsible and that there were others on the ground responsible as well."

Malaysian and US investigators have said that whoever diverted the airplane was familiar with its navigational and communications systems. The Aircraft Communications Addressing and Reporting System and transponder were both switched off within 50 minutes of takeoff - suspiciously, at a location between Vietnam and Malaysia where radar coverage is spotty.

Investigators say that the flight not only deviated from its planned route, but zigzagged in in a way that might have been designed to evade detection. Initially headed northeast toward Beijing, it then turned west over the Malacca Strait before turning again toward the Indian Ocean.

Flight 370 took off at 12.20am March 8 and disappeared about 1.30am. Malaysian authorities say, however, satellites picked up signals from the flight until 8.11am, which is also about the time it would have run out of fuel.

At his news conference in Sepang, outside Kuala Lumpur, Najib said investigators were focusing their search now on two air traffic corridors - a southern one heading from Indonesia to the southern Indian Ocean toward Australia; the other a northern corridor which would have taken the flight toward Kazakhstan and Turkmenistan.

"Due to the type of satellite data, we are unable to confirm the precise location of the plane when it last made contact with the satellite," Najib said.

Aviation experts believe, however, it is unlikely that the plane headed northward because it would likely have been picked up by India's land-based primary radar systems or that of other countries along the route, including Thailand and Myanmar.

"A Boeing 777 would always be picked up on primary radar coverage. It is not like a stealth bomber," said Mikael Robertsson, co-founder of FlightRadar24, which tracks about 120,000 airline flights per day, in a telephone interview from Sweden. "If it flew over land, some country would have seen it on the radar. It is more likely it flew over water where it went undetected."

India announced today it has put on hold its search for the missing plane at the request of the Malaysian government which wants to reassess the week-old hunt.

India had been searching in two areas, one around the Andaman and Nicobar Islands and a second further west in the Bay of Bengal. Both searches have been suspended, but may resume, defence officials said.

"It's more of a pause," said Commander Babu, a spokesman for the country's Eastern Naval Command.

"The Malaysian authorities are reassessing the situation. They will figure whether they need to shift the area of search."

In his statements yesterday, the Malaysian prime minister belatedly confirmed what US intelligence has been suggesting for days - that the flight's disappearance was the result of a deliberate act - a theory that Malaysia has been dismissing for much of the last week. The prime minister, however, declined to characterise the incident as a hijacking.

"Despite media reports that the plane was hijacked, I wish to be very clear we are still investigating all possibilities for what led Malaysian Air flight 370 to deviate from its flight path," he said.

Malaysia's announcement on Saturday came after days of fruitless searches along the flight path. At the last count, there were 14 nations participating in the search, deploying 43 ships and 58 aircraft.

State-run media in China, which sent a fleet of eight ships to search for the missing plane, reacted furiously to the belated acknowledgement by Malaysia of apparent foul play.

"Given today's technology, the delay smacks of either dereliction of duty or reluctance to share information in a full and timely manner," the Xinhua new agency complained in a stinging editorial. "And due to the absence - or at least lack - of timely authoritative information, massive efforts have been squandered, and numerous rumours have been spawned, repeatedly racking the nerves of the awaiting families."

The news agency also accused the United States not being forthcoming about intelligence it had gathered about the flight.

In Beijing, family members of passengers who watched the Malaysian prime minister's press briefing on a large-screen TV at a hotel reacted to the news of the suspected hijacking with astonishment and even a little relief.

"Do you think they might be alive?" one man was overheard asking another as they waited outside the conference room.

"They could be alive," responded another.

KEY EVIDENCE

There are three pieces of evidence that aviation safety experts say make it clear the missing Malaysia Airlines jet was taken over by someone who was knowledgeable about how the plane worked.

TRANSPONDER

One clue is that the plane's transponder - a signal system that identifies the plane to radar - was shut off about an hour into the flight.

In order to do that, someone in the cockpit would have to turn a knob with multiple selections to the off position while pressing down at the same time, said John Goglia, a former member of the National Transportation Safety Board.

That's something a pilot would know how to do, but it could also be learned by someone who researched the plane on the Internet, he said.

ACARS

Another clue is that part of the Boeing 777's Aircraft Communications Addressing and Reporting System (ACARS) was shut off.

The system, which has two parts, is used to send short messages via a satellite or VHF radio to the airline's home base. The information part of the system was shut down, but not the transmission part.

In most planes, the information part of the system can be shut down by hitting cockpit switches in sequence in order to get to a computer screen where an option must be selected using a keypad, said Goglia, an expert on aircraft maintenance.

That's also something a pilot would know how to do, but that could also be discovered through research, he said.

But to turn off the other part of the ACARS, it would be necessary to go to an electronics bay beneath the cockpit. That's something a pilot wouldn't normally know how to do, Goglia said, and it wasn't done in the case of the Malaysia plane.

Thus, the ACARS transmitter continued to send out blips that were recorded by the Inmarsat satellite once an hour for four to five hours after the transponder was turned off.

The blips don't contain any messages or data, but the satellite can tell in a very broad way what region the blips are coming from and adjusts the angle of its antenna to be ready to receive message in case the ACARS sends them.

Investigators are now trying to use data from the satellite to identify the region where the plane was when its last blip was sent.

GUIDED FLIGHT

The third indication is that that after the transponder was turned off and civilian radar lost track of the plane, Malaysian military radar was able to continue to track the plane as it turned west.

The plane was then tracked along a known flight route across the peninsula until it was several hundred kilometres offshore and beyond the range of military radar.

Airliners normally fly from waypoint to waypoint where they can be seen by air traffic controllers who space them out so they don't collide.

These lanes in the sky aren't straight lines. In order to follow that course, someone had to be guiding the plane, Goglia said.

Goglia said he is very skeptical of reports the plane was flying erratically while it was being tracked by military radar, including steep ascents to very high altitudes and then sudden, rapid descents.

Without a transponder signal, the ability to track planes isn't reliable at very high altitudes or with sudden shifts in altitude, he said
