Was there are fifth daughter to be murdered and buried with them? If not then the dna proves who they are.
Sigh, unfortunately, some do believe in a fifth daughter!
A woman named Alexandra DeGraffe claimed to be a child born during Alexandra's 'false' pregancy in between Anastasia and Alexei- legend has it the royal couple were too ashamed to admit they'd produced another girl, and sent her to live in Denmark where a servant of one of the royal relatives adopted and raised her. Another account says Phillipe the mystic, who predicted Alexandra would have a boy, stole the girl at birth to hide his failure and gave her to a Dutch family. Yes, she and AA did meet, and at one time called each other 'sister.'
Seriously, though, I know what you're saying- four different female bodies have been found and all match Alexandra, which should be the end of any speculation. Sadly, there are a few people who have even claimed that the bone fragments found last year were taken from the mass grave instead, and were actually just parts of one of the other three bodies! This is totally unrealistic, since by the accounts of the Reds, they burned the two bodies first, and everything else was dumped in the mass grave. This means for anything from the mass grave to be in the burn pit someone would have had to intentionally take it out, burn it to match the burned bones, and rebury it in the burn pit. WHAT would be the purpose of that? It couldn't be to trick DNA researchers later, since at that time no one had any idea such a thing would ever exist. Also remember they were pressed for time and racing against sunup which is why they went ahead and buried the rest of the bodies, so it is illogical. Some people are just too desperate to believe AN (or Alexei) got away and keep coming up with wild theories. This is why NO amount of testing or DNA profiling of four separate girls will ever stop them. They don't accept the results now, and they'd also reject those, saying they were switched, bungled, tampered with, rigged, etc.
But I do disagree this will never end, it will. There are only a handful of about five or six people who believe these strange things, and eventually they will all die off. We just have to prevent them from recruiting any proteges' in the meantime.
