'The 850-square-kilometer swath of the Indian Ocean where officials have focused their hunt for missing Malaysia Airlines Flight 370 probably isn't the right place, the joint search agency said Thursday.
The area off the coast of western Australia is not the "final resting place of MH370," the Australia-based Joint Agency Coordination Centre said.
Pings were not from Flight 370... now what?
Officials zeroed in on that zone after acoustic pings originally thought to be from the black boxes of the missing plane were detected in early April.
"The Australian Transport Safety Bureau (ATSB) has advised that the search in the vicinity of the acoustic detections can now be considered complete and in its professional judgment, the area can now be discounted as the final resting place of MH370," a statement from the JACC said.

But Australian Deputy Prime Minister Warren Truss defended the country's efforts in the southern Indian Ocean.
"We are still very confident that the resting place of the aircraft is in the southern ocean and along the seventh ping line," Australian Deputy Prime Minister Warren Truss told parliament Thursday.
"We concentrated the search in this area because the pings and the information we received was the best information we had available at the time. And that is all you can do in circumstances like this ... follow the very best leads."
Unlikely to be from Flight 370
Hours earlier, a U.S. Navy official told CNN that the pings at the center of the search for the past seven weeks are no longer believed to have come from the plane's black boxes.'
