Burial records for unclaimed deceased in 1990s? Also police records?

[Gibel]

In Switzerland if the body is buried in a grave, the grave is only rented/loaned for a number of years generally around 20 to 25 years. The grave is then dug up and then reused. Although somewhere there will be a record of a burial there is unlikely to be still a gravestone for that person.

The entry in an Irish newspaper seems very likely. Maybe someone in the village where he grew up may know something perhaps a request in the local paper might bring forth information.

Thank you everyone, for your most helpful replies.  I'll certainly follow up on the links provided. 

As to finding out more from his Irish relatives, many still live in the same village and surrounding areas and either won't talk about him or don't know anything about what happened to his remains or what he was up to.  My co-researcher has been to Ireland and personally spoken to/contacted a great number of them but learned nothing.  He was born in Ireland but lived in Yorkshire for most of his adult life (he came over with his parents when a child) and it seems that not many of his Irish family kept in touch with him or his parents.

As to him being wanted by the Irish police, all that's been admitted by his relatives is that in his own region, there was a 'hit' out on him.  This, of course, opens up speculation that maybe the 'hit' was eventually carried out in Ireland and that the Swiss death notice is unconnected - but then there would presumably still have been a burial in Ireland that would have shown up in the records already examined by my co-researcher.  In any case, such a death would also have likely been reported in the Irish press.  But speculation of course, is apt to run wild.  It may be that the real story is far more prosaic.

Thank you again for all your suggestions.
