After investigation, unclear how Praljak got the poison

Description

This is a TV news item, on the network N1 (in Croatia, Bosnia, Serbia; in Croatian language) on the investigation that the International Criminal Tribunal for the former Yugoslavia conducted on the suicide of Slobodan Praljak in the ICTY courtroom during the appeals judgment hearing on November 29, 2017. I was asked to comment if the results were suprising and what we expect next to happen.
