^ It was concerning that the blood wasn't picked up till the 3rd examination though^
The first examination was not done under forensically rigorous conditions so there was no surprise there at all. The boot was presumably looked at for a body, clothing, anything else suspicious, in the rain and in poor light therefore it was not surprising that the blood was missed.
Under proper laboratory conditions the blood was detected in a pattern consistent with a body have been in the boot. It would have been impossible for an individual to have 'placed' a pattern of blood like that - and, if, as alleged, Linda Razzel had returned to the car a few days later before it was seized, then how come no-one saw her? Why would she have done that - if you want to leave your husband you do not sneak back with the risk of being seen to plant evidence to suggest that he killed you.
She left with no clothes, no money, no passport.
Any suggestions that she knew Halliwell were spurious allegations.
There are miscarriages of justice but I do not believe that this was one of them.
