Six weeks after Russian President Vladimir Putin declared all-out war on Ukraine, pictures emerged of what appeared to be Russian armed forces killing scores of Ukrainian civilians in Bucha, a once heavily wooded and leafy city in Ukraine’s northern province. The city became enmeshed in Russia’s “Kyiv offensive”—a foundational assault in Putin’s war. Calling it “horrifying,” the UN’s human rights chief, Michelle Bachelet, described images of civilians lying dead on the streets and bodies piled into improvised graves.

What became known as the Bucha massacre took place just minutes away from the home of the leader of one of the country’s most prominent law firms.
