At least 117 dead dogs found in 'horrific scene' at California 'no-kill' shelter

2. A certain number will also get sick and either die or need to be put down

There are certainly non-nefarious reasons why this facility would have animal carcasses they need to dispose of, and it may be that burying the remains is all they afford to do with them. And people bury dead pets (and human bodies of course) all the time, not like it's inherently some awful thing to so. It's also possible there was a bad disease outbreak, and some sick animals needed to be culled.

When I read 'no-kill' I don't assume there are 0 circumstances under which some animals will end up euthanized, just that it's not done wantonly and based purely on time restrictions.

So, I'm not going to jump to conclusions without hearing the owner's side of the story. However if they're all just recently shot, and their bodies left to rot above ground, that's a very different scenario of course.
