The investigation into Malaysia Airlines Flight 370 is now classified as a criminal investigation, The Wall Street Journal reported, citing the Malaysian police chief. Inspector General of Police Khalid Abu Bakar said authorities have already recorded more than 170 statements and will interview more people for the Flight 370 probe, the Journal said. But Bakar cautioned that what happened with Flight 370 might still be unknown after the investigation. He added that the investigation into the flight simulator in the pilot's house is still inconclusive. Authorities are awaiting an expert's report on the simulator, he said. After three and a half weeks, the search for the missing plane has come down to this: a lot of floating rubbish, hundreds of heartbroken relatives and, now, quibbling over words all acknowledge offer no clues into what happened to the doomed plane.

Still, even if this new transcript offers no clues about the plane's mysterious disappearance, the discrepancy has provided fresh fodder for critics of
Malaysian's handling of the investigation.
