Nearly all body fluids fluoresce in the light from a black light: semen, urine, vaginal fluids, saliva... Doesn't even have to be human.
I've told this before, so some may remember. A colleague of mine from work told me of his former experience at a meat processing facility. USDA inspectors would shine a black light on and around hanging carcasses of cattle in cold storage (and other areas as well) to look for signs of rat infestation.
Rats poop and pee constantly as they run around. Their urine trails will show up under black light.

Semen?
Saliva?
The type of light used by CSI's? And once a fluid has been found, it has to be
analyzed to determine what it is.
Some of the room photos showed squares of carpet that had been cut out and removed. I imagine this is why -- to determine the kind of dried fluid. To my knowledge, we have never heard the results of that testing, so we don't know exactly what the fluids were. We probably won't know unless someone asks Kolar about it and he is willing to answer.)

otg, thank you very much for explanation. Very interesting, indeed. So, we have 'something' (or maybe 'nothing') ON the bed and SURROUNDING carpet. If 'something' then the only logical explanation of the body 'dried fluid' ON the bed and SURROUNDING carpet could be urine, right? not the stains from Pepsi-Cola

?...
body fluid!....I can understand ON the bed, knowing JBR had bedwetting problem while sleeping....but SURROUNDING carpet is entirely different matter!...JMO. Anyway, while we're talking about body fluid, I have some thoughts...please correct me if I'm wrong.
I have 4 grandsons. Usually, boys need longer time to learn the potty training than girls. By age of 3, they've ware the 'training' diapers or some kind of nightly pants, preventing an accidents. But, accidents have happened regardless, leaving stains on the bed sheets. And of course, if they
wouldn't have ware the diaper and were 'late' to run to the toilet - the urine will be on both:
on sheets and on carpet.
Now, according to ST - JBR still using diapers. Her closet door was opened and diapers bag was hanging out...but we don't know if she used diaper THAT night. We only know what PR said: she took-off JBR's black pants and put johnlong pants, instead. When JBR was found death in WC, she wasn't waring diaper.
Her blader was empty. The
urine was on the FRONT of longjohn and Bloomy oversized panty, as the last 'pee' when she dies. So, we have couple scenarios here.
Scenario #1.
JBR did bedwetting that night.
IF we'll believe PR/JR story that JBR was asleep after FW party (means, did not went to the bathroom before going to sleep and did not ware the diaper!) and her sheets 'reeks the urine' next morning THEN
-
PR/JR LIES: JBR wasn't originally dressed in johnlong pants!. Johnlong pants was part of the re-dressing 'staging'!
In this case, it's very possible that urine can be found ON the bed and surrounding carpet (however, the
stain on the carpet coud be not related to this specific night, just possibility/speculation). On the side note, according to Kolar, the toilet paper was found inside of the toilet bowl. So, it's possibility that JBR was using the toilet that night.
Scenario #2.
JBR did NOT bedwetting that night.
IF we'll believe PR/JR story that JBR was asleep after FW party (means, did not went to the bathroom before going to sleep and did not ware the diaper!) and her sheets 'reeks the urine' next morning THEN
- the sheets wasn't changed since prior nights;
-
ACUTE SEXUAL INJURY was part of the 'staging' . Otherwise, she would pee after such an assult and head blow to follow, regardless of strangulation! and hence it would be different urine pattern and quantity...which would lead to...
PR/JR LIES: JBR wasn't originally dressed in johnlong pants and johnlong pants was part of the re-dressing 'staging'!
Please, please - let me know where I'm wrong with above 'analysis'....
