Ideally (to me) if he were to make reparations, he would begin by returning the $200 per month he accepted from her. He would then pay additional money to cover medical care, the time that will be spent getting them back to health, and the general damage caused to her animals.

Wait, according to the last post before you showed pictures. You knew they had mites but he seems to have though he had them under control? Also, you missed payments for 3 months meaning he would have been feeding them out of his own pocket. Did these animals breed and lay before or during the time of nonpayment?
He has. He's been posting on Facebook about the situation, but he is aware of the thread here. He has deleted some of his posts on Facebook (like the one below) after the fact, so perhaps that is why he is avoiding a site where his posts cannot be deleted.
Charlene I think that now would be a good time to make a detailed list with supporting paperwork of all the financial losses you have experienced due to this experience with Eddie.
Include the estimated costs of extra rodents you are feeding now to make up for their starved condition, the costs in time and gas to pick them up, and get in writing from both vets (for medical costs) and experts (other sellers) as far as time lost to you and your business to get the snakes back into shape, and a list of snakes which may have been so stunted that they will never be able to fully perform either as breeders or saleable pets.
It is best to do this now, while this incident and the expenses associated are fresh on your mind.
Back up rat costs with past invoices if you have any from companies you did purchase from.
You can't take too many picture right now. And take the time to get together as many 'before' pictures as possible.
Take the time you need, you have been through a lot. My suggestions were made for your benefit, so that you have the info to return to, after the hustle and bustle of getting everything going again.Please be patient with me
OP I think it would also help if we knew:
- How many snakes you left with Eddie,
- When the t-stat/heater malfunction actually happened, and when you found out about it,
- How many of your snakes were lost due to the t-stat/heater malfunction, and how many survived but stopped eating due to heat-related injuries, and
- How many snakes you got back, and the condition of all of them now.
Also in the screenshot on the prior page Eddie is claiming your snakes had mites when they arrived. Did you have mites in your collection when the snakes went to Eddie?
We also gave Eddie all our rats and rat racks. Which said rats had been producing and feeding our entire collection before Eddie even got them. We only had to buy extra small rats every once in a while. So not only was he getting 200 a month except the months we missed but he also got all our rats, mice, and asf's.
Only two of our animals actually laid while in his care. One we were splitting and the other was complete slugs. All animals from the clutch we split perished in the overheat. At least that was what we were told.
Charlene - I was under the impression that Eddie used ambient temps to control the temps in the room. Did the whole room overheat? I am more familiar with hearing about tstat failures in rack temps as opposed to the temps in the room...
So sorry for all that you've gone through. Did Eddie make you aware of the large number of your snakes that died prior to you getting them back?
I understand that. I also understand that the little SOB's are pernicious and difficult to eradicate in large collections, especially if proper QT isn't observed.Even if the OP did have mites when they arrived with Eddie, that was back in DECEMBER. That is 9+ months of failed treatment.
