Today, On Deadline is looking at a massacre in Moscow and how it could affect Russia’s ongoing fight with Ukraine and reverberate around the world … down to how much we all pay at the gas pump and who we’ll vote for in November. Last Friday, four gunmen opened fire at a theater near Moscow and slaughtered more than 100 Russians. 'On Deadline' is hosted and produced by Lauren Barry. It's also produced by Joe Hiti, Christy Strawser and Myron Kaplan. Sound design by Joe Hiti.
