If I'm not mistaken, momma deer leave their fawns alone for longish periods while momma goes a-browsing. Supposedly the fawns do not have an odor and thus do not attract predators and they just lie there in their spotted camouflage for the time momma is away a-browsing.
Then along comes a well- meaning human, who thinks, "Oh an abandoned baby deer. Awwwww. Let's take it home to nurture it and feed it and cuddle it and love it. Awwwww. We should name it Giggles."
So then momma deer gets all frantic about her missing fawn when she gets back. And goes throught the pain of an overloaded nursing bag for a few days.
If you find a fawn in the forest, leave it alone.
They should have left it alone.
I have a hard time with the notion that these well-meaning so-called "animal protection" folks didn't know that.
The euthanization I can't explain, except for the fact that it might be some kind of law. Wildlife laws and regulations are wierd sometimes.
But if they had left the fawn alone in the first place, the euthanization would not have happened and momma would still have her fawn and still be nursing it.
