The bloody palm print on the nightdress is of interest.
I wont bother with considering JB or a hitman as the killer...for the fingernail gouges on Ralph's arm and other things satisfy me fully the Sheila killed the other 4.
With schizophrenic killers it is fairly normal for them to go through some ritualistic behaviour after the killings took place. Sheila seems to have followed this well known pattern in her changing clothes and cleaning herself.
Her nightdress being clean and without blood from others and no firearms residue or other mess it seems being worn by Sheila after she had washed post killing.
The bloodstains eventually deposited on Sheila's nighdress all seemed to have been sourced from herself with no reason to think they may be from any other person.
we then need to theorise...
The blood on her right palm can only have come from after the first wound was delivered.
If a suicide attempt and palm bloodstain made by herself ......
after getting blood on her palm she makes contact with her nighdress.....maybe she then passes out for a while.
There should be blood on her right palm...hmmm
There was an interval between the first and second shots.....OK
The blood on her right palm dries ....so when she picks up the rifle to shoot herself the second and fatal time no blood is deposited on the rifle from her palm.
Sheila has a bloodstained right hand...(hmmm we dont see her palm in the photographs).
So unless some naughty policemen are lying...her hand should be bloodstained on the palm.....
ah...so maybe someone cleaned her hand ....
ah ...what about Sheila...she shoots herself the first time....gets blood on her palm.makes the palm print... some time after this but before shooting herself the second time...she decides bizarrely to wash her hands ?.... SORRY DONT BUY THIS ...JUST TOO SILLY FOR WORDS .
so if some police are not lying and her hands were clean...then could the ones who are seeing the clean hands be telling the truth because some naughty policeman has cleaned her hands before the other police saw her hands...
Now why would they be doing that?
Why tamper with the evidence?
or was her palm really bloodstained all along and lies are being told in order to frame JB and cover up a police screw up.
But at this point in time the Police believed that Sheila HAD done it. Why would they wash her hands to make it look like she didn't?
to frame JB as the other relatives had info that would blow apart the suicide story the police had been concocting and had kept covered up..
poor framing though ...hence the relatives latched onto it and used it to their own advantage...
remember it is the police that claim her hands were clean...IT STICKS OUT IN EVIDENCE THAT THEY WANT PEOPLE TO FOCUS ON THIS POINT... wonder why?..
in the suicide case ...it may be that its reported her right palm was bloodstained...
that and other reasons may be why statements etc from that investigation have never been released as it would blow the whole murder case against JB apart.
The police clean her hands but it implies JB must have done it...for we should expect the bloodstains to be on the rifle...if Sheila shot herself... but not if someone else shot her.... but this fails to take into account that the bloodstains had time to dry between the first and second shot so accounting for no palm print on the rifle!...so the idea that some bright spark bent EP officer had...was not such a good one as first thought.
think about it...Sheila cant possibly have cleaned her own right hand after shooting herself...that makes no sense and if someone is trying to fake a suicide they will do their best to make it look right...
Going by the silly JB did it story....erm he shoots her somewhere else....bloody hell why no blood on her feet or clothes from others


? etc but somehow he manhandles her from the first suicide location to a second location and waits and waits...for time between shots prove this...
and then he delievers the second shot... but just a minute...Sheila has blood on her right palm and there isnt any on the rifle...DOH....What to do

oh dear as well best not notice the bloody palm print on Sheila's nightdress thats so damn obvious...
I know thinks JB...to get around the no bloody palm print on the rifle I will wash Sheila's right hand...that'll sort it and trick the police etc....as he cant see the palm print thats staring him in the face...
So JB washes Sheila's hand very very carefully before staging her hand on the rifle...just as the police did..... happy now JB ignores the bloody palm print that was made by Sheila's hand as the police will not see that or think how it was made and that Sheila's hand had been bloody once but wasnt when found..hmmm
so a rather incredible tale eh....I think so...
why didnt he just leave it ...her hand as is if the bloodstaining on the hand was dry by this time..it would be on no consequence....and if still wet...then it would have made a palm print on the rifle anyway..
its a lot of trouble washing her hand and not leaving traces...and it takes time... CAN WE THINK OF A BETTER MORE CONVINCING RUSE...?
I can... place Sheila's hand onto the wet bit of bloodsoaked nightdress and then place it onto the rifle to leave a corresponding palm print... only takes seconds and accouts for the palm print on the nightdress.
hmm GOOD IDEAS eh..
How about naughty policeman...he could place Sheila's hand on the blood and then onto the nightdress and then wash it.... and leave out the rifle ..just to make it look "if needed" like someone else shot Sheila and screwed up as her palm print wasnt on the rifle.
