Event follows a nighttime event reported on July 4/01 at 21:15 hrs. (AST) of the sudden sighting of a comet-like structure at same height, which shifted shape and position turning into a fluorescent cloud that moved over SW portion of town. Said sighting was reported by people as far apart as 7-8 kilometres, during a span of over 15 mins, and was reported on local press. Some of the spectators reported said sighting as if "the comet had appeared out of nowhere, like "when you see ships appearing out of 'wormholes' in movies". That same night, attacks on fowl and rabbits by the ill-famed chupacabras (or goatsucker)were reported in the vicinity of Barrio Jobos, on the NNW side of Isabela's municipality - photographs of the attacked dead animals and the torn-up cages have been taken and are available to serious investigators. These attacks and sightings have been ongoing for over 2 years and are still being ignored by most authorities.
