A lot of these older cases are being solved and will be solved in our lifetimes. So many doe's have been identified n the US during the pandemic. Advances in technology means forensic are able to do more and go back and test items for DNA. I think it's amazing. Obviously in these cases the perpetrator may have long since passed away so will never face justice but at least some answers are found.
I'm hoping to get up to Manchester to visit the Angel of the Meadow's grave at some point. I doubt she gets many visitors and it's a case I really, really want to know the answers to.
This is a UK Doe case I've been looking into. Who is Katrina? Did she murder him? Was it a double murder and she washed up elsewhere? Looking into marriage records may help but If they're Greek like I suspect then that may make it more difficult. There can't be many Georgio and Katrinas married in 1956 and it would be easy to rule out those who are alive or known deceased.
