The man in question decided not to disclose his identity due to the very real fear of being mocked when events of this sort occur. While he refused to go public with the event, a friend convinced him to go public in Diario San Rafael and after being promised that his identity would not be made known, he provided the information to the paper's newsroom.
According to Diario San Rafael, it all began last Saturday around 15:00 hours in the vicinity of the Nautical Club, when the protagonist approached the shoreline to ascertain fishing conditions, as he is an avid fan of the activity.
