James Lawrence Day, known to some as Larry, was 50 when he vanished from the Montague Island area in Alaska on September 27, 1990. He owned and operated the fishing vessel Days End and was last heard from during challenging Gulf of Alaska conditions that day. The next day the Days End was found capsized on the northwest end of Montague Island.

The Alaska State Troopers led a search and rescue effort after the overturned vessel was discovered. James Day, described as a white male with brown hair, blue eyes, 5 feet 9 inches tall, about 180 pounds, with a scar on his right knee and believed to have been wearing brown rain gear, was not found despite extensive repeated searches of the coastline and waters. The investigation remains open in Anchorage and the circumstances of his disappearance are unresolved.

Did anyone who fished around Montague Island or was in the area in late September 1990 see the Days End or James Day?
