I (regrettably) read something last night that puts a bit of clarity in some of the bizarre relationship part of all of this, if that is even possible.
These four people: KR, his GF, CR and KR's ex-wife judge were all swingers.
Actually saw a pic of the deceased together with the judge, the ex-wife of small man syndrome. The two of them are sitting at a table together.
If my suspicions are right, these four were all screwing around together, little man divorced judge and took up with deceased's wife.
Judge has had to recuse herself from this case likely because she knew all of these people, probably intimately. No wonder no one wants this to go to trial! Gov. Abbot appointed her to the judgeship! Total cluster fark.

Sorry to go Jerry Springer here and I could be wrong, but I'll about guarantee this is the case and in the end will all come out with prosecution.
