I know from working in healthcare in Germany, that you can get euthanasia as a non Swiss national if you go through the appropriate channels. You don't even have to live in Switzerland.
But it is for all a legally controlled, very lengthy and detailed process with several independent doctors and psychiatrists having to sign off on it.
My uneducated guess would be, that there are some rules and regulations they haven't followed exactly. Maybe they thought since the patient has the controll over the button themselves, they wouldn't be bound by all of them.
I hate this so much.

Maybe you can start teaching her boundaries, by making one space in your loft off-limits.
Like don't allow her on the bed or on the sofa or whatever is your relax place. Be gentle, firm and consistent and she will lean that she isn't allowed at that exact space. Maybe that can give you a little distance.
I'm not criticising that police couldn't find him themselves. My issue is with the statement, that this is an outcome they "strive" for as if finding him after 70 years (SEVENTY) was an ideal outcome in a child abduction case. As if this was the most they aim for.
One thing stood out to me in OPs post and I want to add one point to that.
She's destructive, she doesn't know what boundaries are, etc.
Well, yes. She's a kitten, a baby. She knows about as much about boundaries than a toddler. She will not learn that on her own, or only up to a certain level. Just like a puppy she needs you to teach her and show her boundaries. Cats might not take orders like dogs do, but they still need guidance and training. If they can't learn from their morhers their human needs to fill this role.
