The Marine Corps says 12 Marines involved in a mid-air helicopter crash off the Hawaii coast are dead.  The status of the Marines was changed to "deceased" since five full days of search and rescue operations failed to find any signs that they were alive.

The Marines were taking part in a nighttime training mission last week when two helicopters they were in collided in mid-air off of Oahu.  The search for the Marines was suspended at sunset Tuesday.
