What happened to Alexei Romanov?

Alexei Romanov was murdered along with the rest of his family, doctor and servants. The report of the killing by Yakov Yurovsky , who was in command of the detail that kept the Romano vs in custody has been found and it clearly states that all, even young Alexei, of the Romanovs were shot and buried. In addition, there is an eyewitness report by one of the guards, Pavel Medvedev, confirming that Alexei was killed.

After several months in custody of the Bolsheviks, Alexei was suffering badly and in great pain because of his hemophilia. He could not walk on his own at the time.He likely would have died soon anyway. The only way he could have survived is if the Bolsheviks, who murdered every other member of his family, actively cared for him to keep him alive. Now why would they do that?

The most compelling reason to disbelieve any story that he survived is to realize that the murder of Alexei was the second most important murder of all of the Romanovs, even that of Alexandra. Once Nicholas II was dead, Alexei had the right to succeed to the throne. The only way to ensure that no Romanov ever again became Tsar was to kill the entire family, but Nicholas and the Tsarevich had to go first before the women. There was no way the Bolsheviks would have allowed Alexei to live.
