If they weren't there on the 27th there wouldn't be any sightings.Yes absolutely, assuming the witness is sure about what he has seen and if these 'fishermen' are local to the area it's difficult to imagine they don't have knowledge of what's been occurring there these past two and a half weeks. If they're not locals then with all the publicity they would know they had been in that area in the last couple of weeks. I'm a little surprised no one else has mentioned a sighting. I don't know the area but it doesn't sound like we're talking sleepyville with tumbleweed rolling through the streets. Lots of cut through traffic and school runs at that time of day
The information has only recently appeared in the media so there's no reason why these people would have come forward before it was reported
