Searchers said Sunday four fishermen missing after their boat apparently sank off Oregon had passed the time they could be expected to survive. The U.S. Coast Guard continued looking for the crew of the Lady Cecelia Sunday but reported no sign of them other than some debris and an empty life raft. Petty Officer Shawn Eggert told The (Portland) Oregonian, \"We have been searching longer than a survivable time.\" Ships and aircraft were dispatched to the area Saturday after an automated distress signal from the Lady Cecelia was received. Searchers located some debris and the raft floating amid an oil sheen on the water. The 70-foot trawler had sailed from Warrenton with four people aboard. The names of the missing mariners were not immediately released.
