Not knowing is the worst...

It happens...

You have to check your husbandry, check your room, make sure nothing is off, and then, take the body to the vet for a necropsy if you are that intent on finding what happened.

Its never fun, but its part of dealing with live animals.

I was also going to suggest a necropsy - at least that way you'll know if you're dealing with something that threatens the rest of your ball pythons or not.

sometimes, just like in people, there's some kind of ticking time bomb condition(blood clot, heart attack) that is just not predictable. I hope the rest of your animals stay healthy, sorry to hear about your loss.

Sorry for you loss.

A friend of mine is a farmer and he has a saying that may help?:

"When you have livestock, you have deadstock."

As long as you take good care of your animals I wouldn't be too worried. Though if it's not too late, you could take it to a vet and get an autopsy.
(I know its called something different for reptiles. Just can't think of what.)
