To find out the answer to "What happens to people who die without any next of kin?", watch "A Certain Kind of Death" documentary. Netflix has it on instant play. You can watch it on YouTube as well. Try to watch this documentary and think about life in general and yours in particular. It was a sobering experience for me.
