Dutch prosecutor Digna van Boetzelaer said Thursday that “the investigation has now reached its limit”.
“All leads have been exhausted,” she said, as the team began laying out the evidence it uncovered in its long-running investigation.
Dutch prosecutors said in their summary of findings that “there are strong indications that the Russian president decided on supplying” a Buk missile system to Ukrainian separatists.
A Buk system was used to bring down MH17 on July 17, 2014, killing all 298 passengers and crew.
None of the suspects appeared for the trial and it was unclear if the three who were found guilty of multiple murders will ever serve their sentences.
The convictions and the court’s finding that the surface-to-air Buk missile that blew the Amsterdam-to-Kuala Lumpur flight out of the sky came from a Russian military base were seen as a clear indication that Moscow had a role in the tragedy.

Russia has always denied involvement. The Russian Foreign Ministry accused the court in November of bowing to pressure from Dutch politicians, prosecutors and the news media.
But the November convictions held that Moscow was in overall control in 2014 over the self-proclaimed Donetsk People’s Republic, the separatist area of eastern Ukraine where the missile was launched. The Buk missile system came from the Russian military’s 53rd Anti-Aircraft Missile Brigade, based in the city of Kursk.
The team has continued to investigate the crew of the Russian Buk missile system that brought down the plane and those who ordered its deployment in Ukraine.

“The indications for close ties between the leadership of the Donetsk People’s Republic and Russian government officials raises questions about their involvement in the deployment” of the missile, the Netherlands Public Prosecution Service said on its website, citing intercepted phone calls between leaders of the breakaway region and “high-ranking Russian government officials held in the summer of 2014”.
