"We've been able to identify nearly all the members of the 53rd Air Defense Brigade which was in this convoy that took this missile launcher to the Ukrainian border," Higgins said, adding that the international investigators "might have a lot more information."
"But MH17 is really part of a broader story and that's Russia's involvement in the conflict in Ukraine," he remarked, noting that Russia sent troops and hardware to Ukraine and supported separatists' attacks by artillery fire delivered from within its territory.
"Ultimately the person who made the decision to send Russian troops to Ukraine is going to be the head of the Russian army, which is Vladimir Putin," Higgins added.
