he missile launcher used to down Malaysia Air flight MH17 is probably back in Russia after it was imported into Ukraine a few weeks ago, a well-placed source with access to the latest intelligence told Fox News Friday night.
The same source also said the missile that brought down the plane, killing all 298 on board, was fired from Schnidze, a town in eastern Ukraine.
"We are building a case," the senior U.S. official told Fox News. "It is damn near bulletproof at this point."
The U.S. intelligence community used infrared data, measurements and electronic signals, among other methods, to determine the origin of the missile's path.
A report by the Daily Mail showed the SA-11 launcher used in the attack missing two of its four missiles. A senior U.S. defense official confirmed the newspaper's report.
The local separatist commander who likely ordered the strike, Igor Strelkov -- who was heard in some of the phone intercepts released by the Ukrainian Interior Ministry bragging about having brought down the plane -- will likely be punished by Moscow,
