Investigators say evidence shows the missile that downed a Malaysian aircraft on July 17, 2014 had been transferred from Russia to a rebel-held territory in eastern Ukraine from where the plane was hit. All 283 passengers and 15 crew members on board the Boeing 777 were killed. Investigators say the Buk missile and the trailer from which it was launched were returned to Russia after the plane crashed. Russia has denied any involvement in the crash. Zlatica Hoke has more.
