Actually, when the creatinine was noted, it was heralded as a BORG victory - - trace evidence of urine on the sheet was blown WAY out of proportion and for a short time the PDI theory went wild - - the motive was that wet bed.

But that trace evidence really proved nothing. The sheets were not wet, the trace evidence was found LONG after the murder using sophisticated lab equipment. Any person not trying to prove the bed was wet will tell you that a wet bed doesn't need microscopes to find the stain or smell.
