You may well be on to something. I read up a bit on this particular case, and the (declared) dead Mr. Gricar apparently used his home computer to search for things like how to destroy a hard drive, etc. Here’s a link to the original story on that aspect of the affair:

He may very well be alive somewhere. Perhaps Slovenia, or somewhere else in Central Europe.
Though he’s been declared legally dead, it’s possible he may have sailed into the sunset somewhere nice.
Ray Gricar was not the only one with access to that computer. His live-in girlfriend had access.
It also appears that DA Gricar disappeared just as the statute of limitations expired on the 1998 charges.
