(Newport, OR)  --  Three people are dead after a boat featured on the Discovery Channel show Deadliest Catch: Dungeon Cove capsized Tuesday off the Oregon coast.  The Mary B 2 had requested an escort from the Coast Guard because of high seas Tuesday night.  A few minutes later, the boat capsized.  A Coast Guard boat was already there because of the earlier request and immediately launched rescue operations.  All three crew members were found and declared dead.  None of them had been featured on the show.
