Suspicious boats with decomposed bodies found drifting off Japan

In short: during October and November, at least 11 boats have been found floating off the cost of Japan with only dead folk for crew. The thinking is that these are North Korean fishing boats. What with ongoing famine, coupled with a lack of modern navigational equipment, I guess it makes sense that Nork fishermen would set out on voyages they’re simply not going to come back from, but, dayum. What’s next? Ghost pirates? Pirate ghosts?
