They would not have bothered retrieving or giving the diaper to the FBI. The grandmother threw it away in the church garbage (so she said at least) which was a long time after he went missing. It would have served no purpose since they weren't having to prove DeOrr Jr.'s identity.
If evidence was too degraded or had been compromised, they wouldn't be able to test it. The FBI may have decided it wasn't worth testing because it had no real value to the case.
Here is the only comment he made in the interview last week about behavioral analysis:
09:36
SB: Well, I can tell you that all four people have taken polygraphs. Im not willing to discuss um um the uh
the findings of those polygraphs at this point. Uh were um having some including the FBI look at the results just to give us uh their impression and uh, you know um those are difficult uh interviews and uh you know the polygraph uh experts uh, you know, sometimes they dont agree, so
uh were looking at those real close and were doing a behavioral analysis based on their statements uh at the time of their interview.

I don't think SB and Bonneville County are back at square one. SB said he was going there to discuss where to take the case. I believe him.
