I dare say this kind of thing has happened sometimes,rarely hopefully ? You dont give me enough detail to look anything up,but I am enclosing a link to an article on Cannibalism which is what it seems to be ?
I've heard of worse, so yes it could very well be true.
Cannibalism. Not true.
I heard there was a guy who went camping in the woods and was kidnapped while he was sleeping. He woke up from a soaring pain to find himself tied up and gagged and noticed he was being roasted alive by a serial killer that was lost in the woods and wanted to find a way to survive. In an interview with the now captured killer, he said that the victim quote, "tried to squeal like a pig until his voice fell", and "watched his flesh burn with the smell of flesh in the air". It has also been revealed that the killer may have indeed, eaten the roasted body, but has claimed to have buried the head two days later in what could possibly be a completely different region of the forest, because, since the killer was lost and had no sense of direction, he cannot seem to point out where. The head was never found, but some of the bones, however, were found, scattered near an abandoned tent.
