Good job tracking down this much information!! I'll say a prayer that Brad Edwards will do a story (I'm the one that suggested you contact individual reporters - the funny thing is, we have a Brad Edwards here, too - but he's a meterologist for one of the local stations.)
I'm not sure how you found out about this other lawsuit, but I bet if one has been filed against a horrible breeder like this, that it is very likely that others have also been filed. I know here folks can gain access to court lawsuits through the county or the state and its all online. You should see if there is something of this kind where the breeder resides. You may have to pay a fee to access all the records - but it may be worth it.
Better yet, if the reporter will do the story, he may be able to easily gain access to these records. I know the paper I work for pays some type of flat fee to access the online records.
Also, I don't mean to stick-up for a scum breeder, but some breeders do give the animals vaccinations themselves to cut down on vet bills. But, if your vet said the pup had never had vaccinations, I would trust him.
Please keep us posted. We're rooting for you!!
