The only Russkie narrative I'm aware of consists of using photos of snipers on a rooftop that wasn't even of a building in the same country, along with a bunch of made up BS, which I suspect you will now share with us uncritically straight from an anti-American Russian propaganda website.
There’s no need to go any further than Ukraine’s own official “investigation” of the event, (or better yet ask some of the relatives of the Heavenly 100 what they think) to see the holes in the simplistic ‘Yanukovich did it’ narrative.
