The case occurred on the premises of a marine company that does barge construction and repair work, located near the old facilities of the Swiff packing plant. The premises border on the north with a unit of the Naval Subprefecture, on the south with the Saladillo Creek and on the east with the Parana River.

The events took place on the evening of April 23, 2008 according to information furnished by Mr. Claudio Petri, watchman of the premises. Before leaving his shift at 20:00 hrs, he saw the sudden motion of what he defined as "a shadow" through his office window. When he went out to investigate, he saw nothing unusual. When the shifts changed, he turned over his post to his relief and went away.

Matters developed normally until 02:00 hrs., when the next watchman saw a shadow through the window. Arming himself with a pistol for protection, he went out to investigate. He headed toward a light panel located between the vessels. At that location, he saw a shadow facing him, and according to the remark he later shared with his co-workers, he heard a voice that said: "Mátate" (kill yourself) over and over again, imperatively. At that moment, his wife reached the site (she had been keeping him company during the late shift) and she managed to pull away the gun that the watchman was pointing at his head. At no time did the wife see or hear any of the things reported by the watchman. Returning to the office, the watchman headed for the restroom, babbling "kill yourself" over and over. When the officer-in-charge arrived, he asked the watchman to take a few days off, in view of the state he was in.

Our witness, Mr. Petri, remarks that upon entering at 06:00 shift on 04/24/08, his co-workers apprised him of what had transpired the night before, adding that the sheep they kept at work had also died overnight. Upon seeing the animal, he became aware that it was a highly unusual event. The specimen was missing its upper lip and upper front teeth; its entire right eye was gone, along with the front right leg and muscle mass near the upper joint nearest the body, forming a hole with a depth and diameter greater than 10 cm. Also gone were its right rear nipple and anus. There were signs of hair sheared off in the areas affected by the alleged mutilation, similar to the shaving done during animal sterilization surgeries, but missing all types of fur (sic). There was no tearing of the muscular mass, broken or splintered bones.

Also noteworthy was the fact that there was no sign of a struggle or defense on the part of the animal. Despite the magnitude of the phenomenon, there was no blood spilled on the floor, or traces of blood on the animal itself, or any sign that it was dragged. Even more surprising were the prints found at the site, which were photographed by the witness along with the mutilated carcass. The prints were approximately 15 cm long and have a rear base of support (the point of support that sunk 2-3 cm into the sandy soil) with a front part consisting of three fingers ending in nails or claws. The middle part of the print is not perceptible. The distance between one print and another is of approximately 50 cme. Following the corresponding analysis, it was determined that whatever left the prints walked erect and measured between 1.80 to 2 meters.

We consider this case to be very important by virtue of having occurred within the city limits, along with the chance to have found the "prints".
