Nicolae and Elena Ceaucescu
The bodies of the former Romanian dictator and his wife, who were executed on the fall of their regime in 1989, were disinterred in July 2010 at the request of relatives who wanted to be sure of their identity. DNA tests showed that the bodies were those of the Ceaucescus.
