Stuffed if I know how they're going to ID the remains properly. I'm not aware of there being any living relatives but I guess there is. What are your thoughts on an anthropological and other big words front, Kyt?
There's probably a couple of roots for the boffins - examining the body for the tell-tale wounds (didn't one of the bullets shatter his leg?), and/or DNA, as even distant relatives would be able to provide a modicum of links (though it would depend on what they extract from the body). If he was examined by a prison doctor before execution, there maybe some dental details etc.
