To my knowledge we only have two pieces of evidence and both are not very strong.
I'll do the chronologically second piece of evidence first because it's weaker. This is about the child I will call Six. The key bit comes from Sergeant David Nester's report, in which he says "[Six], when asked about getting clothes, wanted new clothes as she made reference to the fact she had been wearing those clothes more than that day." Slam dunk right? Well no. If you cross reference with Detective Pomplun's report, you see that Six's morning went like this: she's woken up (in basement) at around 9:20am to Detective Pomplun who asks her to come outside with him(?), she goes outside and waits (with family), then when they discuss getting clothes Six speaks up to note she hasn't had a chance to change clothes today (because she was immediately taken outside after waking up). This isn't proof she has been in the same clothes for days, merely that she's still in her sleep clothes. Which could very well be pajamas, or in fact could be the same clothes for many days, we don't know. We (and Sergeant Nester) suspect otherwise because of the next piece of evidence, but our reasonable suspicion is not proof.
The other piece of evidence (chronologically first) is:
the search warrant affiant said the pastor said the schoolteacher said "the children had complained of being hungry, not being fed, and wearing the same clothes for 3 to 4 days at a time and would start to smell" (end of page 2 of the APPLICATION FOR SEARCH WARRANT). I think that it's likely true that the children wore the same clothes multiple days. Addicts neglect (all) things, and I have no particular reason to doubt any of those people. But it's worth remembering that it is a long chain of hearsay, and (to my knowledge) that's really the only evidence we have.
Unless there's a third piece of evidence that I missed?
Anyway, what's it matter? It doesn't matter legally, the search warrant isn't going to be invalidated over this, and if it goes to court they can just bring the teacher to the stand, where it will quickly go from hearsay to direct witness testimony. It matters for us, though, for credibility: I try to only claim to know things that I can prove. I cannot prove this, even if I believe it likely.
