Isnt it strange that people accept the weirdest scenarios to explain how there was no evidence on JB - like wetsuits /marigolds/ getting rid of the clothes ( although the police were at his house the next day) cycling in the dark / doing the murders in the nude. plastic bags on feet etc etc
And yet when it is suggested that Sheila might have washed her hands or even her clothes in a bucket - horror of horrors that is impossible.
BTW don't forget the slippers/canvas shoes the police took and told Anne to say nothing about them
Jeremy left the scene and had ample opportunity to wash and dispose of any clothing he used.
Sheila never left. Her bloody clothing and gloves would have to have been somewhere and worse there is no way for her to have changed out of the clothing she died in which also lacked the evidence it would have had she killed herself while wearing it.
You are also failing to consider Jeremy would have a reason to change and dispose of his clothing- he didn't want to get caught. Someone who has decided to commit murder suicide has no reason to change and try to conceal evidence of having murdered others. That is what people who plan to keep on living but want to avoid spending the rest of their life in jail do.
There are no known cases where someone who decided to commit murder suicide washed up and disposed of evidence proving they committed the crime before killing themself. The closest anyone could come to that is a doomsday religious cult where the victims willingly allowed themselves to be killed, a few people cleaned up the dead bodies afterwards to purify them, cleaned their own bodies as much as possible and then finally committed suicide themselves. That in no way helps to make it plausible Sheila would take a bath and change her clothing before killing herself. The only thing that could make that plausible is if they found clothing she changed from and proof she killed herself. Then the unlikely would be established and there would be a known case where it happened. Saying maybe it happened for the first time ever and police hid the clothing she changed of doesn't cut it. That is what a Jeremy supporter speculates but speculation is enough proof is.
