I found no information how he died .. just "found dead, most certainly suicide" .. some people say he was afraid to go to a US-jail but then why should he miss the chance to talk at a trial what they wanted avoiding him to talk about -- the corruption in some US-departements .. he still could commit suicide after found guilty IF he would have been found guilty so why in Spain ? Someone wanted to avoid that he talks in a public hearing or trial -- no other logical explanation to me ..
