Hill - Duque - Healy - What Killed Divers Under Ice?

The Coast Guard has started two investigations, relieved the Healy's captain, pulled all diving equipment off the ship for examination, and suspended all polar diving. Nothing has been said about what might have killed Hill, 31, and Duque, 22, on Aug. 17, or when the investigations will conclude.

We have found that it is not unusual for the Coast Guard to withhold information about investigations until it concludes its findings.  It must be frustrating for the families but hopefully in the end there will be a thorough investigation that will shed light on the cause of this tragic event and allow the families some closure.
