On June 19, 2019, the Joint Investigation Team (JIT) that was set up to investigate this incident issued warrants for four individuals that they hold responsible: They are three Ukrainian nationals and one Russian national. They were not the crew of the BUK missile launcher, but the men believed to be behind the transport and deployment of the Russian BUK missile launcher.
The Netherlands had already held Russia responsible at an earlier stage of the investigation because they found sufficient information to show that the BUK launcher originated from Russia and was manned by Russian soldiers. Bothe the Ukraine and Russia have laws against extradition of their nationals, so the chances of hearing from the suspects are slim-to-none. So how can we learn exactly what happened?
