Shortly after midnight on December 6th, 1978, Zanfretta was on duty in Torriglia, a village near Genoa. It was a dark and moonless night. It was also very cold and snow had fallen during the day so that there was a dangerous film of ice on the roads. As Zanfretta approached a client's uninhabited country-house (called "Our Home" by the owner, Dr. Ettore Righi), in the area of Marzano, his patrol car, a Fiat 126, mysteriously stopped dead. The car engine, lights and radio all failed seemingly for no reason. At the same moment he saw four strange lights moving about in the garden of the house and stepped outside of his car to investigate with gun and flashlight in hand. At first he thought that burglars were behind the house. So he walked through the open gate and crept along a wall in an attempt to surprise them. But Zanfretta had underestimated the problem and ended being the one who was surprised by what he had taken for thieves. Feeling himself touched from behind, the security guard whirled around and saw something that filled him with terror: only inches away stood what he called: "An enormous green, ugly and frightful creature, with undulating skin, no less than ten feet tall". When he directed the beam of his flashlight on the being's face, he was so frightened that he dropped it, but quickly it up again and run away. While running, he became aware of a large and very bright light behind him. Turning around, he saw a huge, flat triangular form which was blinding in its brilliance. Zanfretta shielded himself from the light with his arm. This thing which he assured was a flying saucer, ascended from the back of the house. It was bigger than the house itself, and produced a hissing sound. Later, Zanfretta said that he felt an intense heat. He made it back to his car and tried to call his security company's operations center in Genoa. It was 12:15 A.M. Carlo Toccalino, the radio operator, has testified that Zanfretta was speaking in an excited and disconnected way. He kept saying: "My God, are they ugly!". The operator then asked if "they" were human and if they were assaulting him. The answer was: "No, they aren't men, they aren't men". At that point, the communication were abruptly broken off and Toccalino called the chief of the security service, Lt. Giovanni Cassiba. An hour later, a couple of other patrol guards, Walter Lauria and Raimondo Mascia, found Zanfretta in front of the country-house, lying on the ground. It was 1:15 A.M.. When he saw them, he jumped up, gun and flashlight at the ready. Eyes bulging, Zanfretta didn't seem to recognize them, nor to understand when they told him to lower his weapon. The other patrolmen rushed and disarmed him. To their surprise, his clothes felt warm even though the December night air was quite cold. They also noticed that the gate was closed as usual. The Carabinieri, the Italian military police, began an investigation on what happened that night and one of the first thing they discovered were clear imprint that some large and heavy object had left on the ground in back of the country-house. There were two of them in the frost covered grass, 9 feet in diameter and shaped like horseshoes. Antonio Nucchi, the commandant of the Torriglia station, has stated that he was every confidence in the testimony given by Zanfretta. In fact, he has known the security guard for many years and, when I asked him what he thought about him, he answered: "I can state with certainty that he is a clear thinking man with no strange fantasies in his head. When we went to investigate the scene the next day, he almost didn't want to come, he was so scared. Only something exceptional could have frightened him so." During the investigation Nucchi discovered that 52 residents of nearby Torriglia saw a bright glare in the direction of the country-house at the same time Zanfretta reported seeing it ascending.
