The last Russian Czar, Nicolas II, was murdered in 1918, along with his family.
They found the bodies of all except a son and a daughter. Some amateur sleuths solved the mystery recently by walking just 70 yards away and digging.
There were several women claiming to be Anastasia thru the years and were found to be lying.
Heres a pic and heres the link. Pretty cool. I'd love to sleuth out something like that.
