Incised cows galore

This little story has me intrigued, not so much by what is reported, but by the total lack of rational questions.

Please, Mr or Miss reporter persons, ask questions and seek answers instead of writing fluff.

For example:
1) Have a coroner determine if the animal was totally drained of blood as the cause of no blood being evident after said surgery.
2) Analyze the incisions and see if there are any indications of use of a knife edge or if some other tool or process was used.
3) Any interesting residue on the wounds?
4) Any helicopters operating in the area over the past month in all the areas where such dead cows have been found?
5) If no scavengers, what is the cause of repulsion? That could be very practical to know for other uses.

All the stories about UFO’s and UAP’s are good tabloid fodder but so far the laws of physics make it highly improbable we are besieged by interstellar visitors.

So please, more facts about what we can analyze and less wild speculation.
