The story is strange. The goonch probably started down the path of eating people by scavenging bodies disposed in rivers in the area, a common practice apparently. Now, some mysterious cases of disappearing people are attributed to a goonch pulling them underwater and eating them.
This is no run-of-the-mill catfish, they're BIG. They can get to be 200 pounds and they are certainly capable of pulling a person underwater. In one case of a disappearing Nepali boy, he was said to be pulled underwater by "an elongated pig." I suppose a goonch could be described as an elongated pig (see photo above).
The goonch that ate people, sounds like a Dr. Seuss book.
