Who is carrying out the cattle mutilations?
From the FIGU Forum (Questions Answered by Billy):
Is there any information or clues which can be "shared" with us, about the nature or source of the "authentic type" cattle mutilations as investigated by Mr. Fernand Belzil, who currently resides near St. Paul Alberta Canada?
Only a percentage of mutilations which he has investigated & documented, he considers "authentic"... in that he/we do not understand how (using our present technologies) these could be accomplished.
ANSWER: Hi Pierre,
Billy doesn't know about the case you mentioned.
He also said that the mutilations are not executed by extraterrestrials, but rather through terrestrial sources, like secret services, experiments, predators, etc.
