[tl;dr: quest for some specific cryo data references]

I prepare to do my own, deeper evaluation of cryogenics. For that I read through many of the case reports on the Alcor and CI page. Due to my geographic situation I am particularly interested in the ability of actually getting a body from Europe, Germany over to their respective facilities. Now the reports are quite interesting and provide lots of insight into the process, but what I still look for are the unsuccessful reports. In which cases a signed up member was not brought in due to legal interference, next of kin decisions and the likes. Is anyone aware of a detailed log of those? Also I would like to see how many of the signed clients get lost due to the circumstances of their death.
