No Passengers Involved With Flight 370 Disappearance
(Perth) -- Authorities say none of the passengers on Malaysian Airlines Flight 370 were responsible for its disappearance. A criminal probe is underway to determine whether sinister motives may have been behind the incident. One Malaysian police chief says the investigation still may not reveal what happened to the doomed jet. After more than three weeks, search crews are still coming up empty-handed. The airliner is believed to have gone down somewhere in the Indian Ocean last month, but there's still no sign of wreckage.
