(CNN) -- 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. 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 Joint Agency Coordination Centre said.
