That was a time of no internet and the news only came to you on TV. The girls who saw the supposed creature were in every channel. But they remained telling the same story every single time. Nothing added, nothing subtracted. There is also a lot of myth regarding this story, some say they saw army trucks coming in and out of the city, some say a man died of unexplicable cause, but that has never been proved as far as I know. Also, to be honest, there's no way something like this could happen in this country and just be kept a secret for so many years (no one coming out and proving something like that was actually real). I do believe the girls saw something weird. The rest of the story, not so much.
