According to Pier Zanfretta, he’s apparently one guy the lizard-aliens couldn’t get enough of. On December 6th, 1978, Zanfretta he was working as a security guard in Italy when he was confronted by 4 reptilian looking beings that stood 10-feet-tall and had green skin. He claimed they hit him with some sort of heat beam, after which he sprinted away. When the scene was later investigated, they found very large strange footprints next to scorched trees.
Then, on December 26 the aliens came back and got Zanfretta. He said they took him inside their ship and attached a communication helmet to him, but when he said he was afraid and wanted to go home, they let him.
THEN, they allegedly abducted him on July 29th, 1979, December 2nd, 1979 and another time in 1980. The last time, the aliens showed him a frog-like being suspended in a tube and claimed it was an enemy of their species.
