Just one thing, the level of water at the bottom of the bowl always stays the same except when there is siphonage in the going away pipe but that is minimal and self regulating, having said that, in extreme cases of siphonage odours can get through. If you pour a glass of water into the toilet then an equal amount will go down the pipe, allthough you may not be able to hear it.
That's precisely my point…
- Siphonage is triggered when water level rises sufficiently to flow over the S-bend into the sewage pipe
- Blood (and maybe also urine) raised the level in the bowl which activated the siphonage… a low volume weak siphonage, not the normal one with a traditional flush when the entire tank rapidly empties into the bowl
- Siphonage occurred which led to level in bowl to be lower than normal (with some audible gurgling sounds which do not occur during a normal flush)
- Bowl water level self-regulating mechanisms activated
- Fresh water slowly trickled from the tank to the bowl to raise level to normal by means of the small nozzles located under the toilet rim
- Fresh water trickling into the bowl partly rinsing the bowl surface leaving the telltale blood streaks
… this explains everything :
- The blood streaks which can only occur when self-regulating water level mechanisms trickles water into the bowl to compensate the low level post-siphonage
- The small wood splitter which did not flush
- The small bullet fragment which also did not flush
I suppose not all toilets work the same but I have tested this on my own toilet and it works just as I have described it…
The alternative is so improbable that it borders the impossible :
- OP flushed the toilet as per the proposed scenario by Judgejudi which is statistically improbable
- OP found a bullet fragment and a small wood splinter, planted them both in the bowl to camouflage the fact that he had flushed the toilet
