As soon as the Ukrainian army declared Bucha safe to re-enter, Volodymyr and Serhiy set out for the apartment building. Inside, they found blood smeared on the floor in the stairwells and personal photographs from people's apartments strewn around. On every door you could see the holes from the shotgun blasts - sometimes one, sometimes four or five. Doors with steel plates had been crowbarred. On one wooden door, where the lock hadn't given way to repeated shots, the Russian soldiers appeared to have become frustrated and blown a hole right through the middle of the door into the apartment. Behind another door, it was clear the homeowners had pushed a heavy table up against the frame in a failed attempt to keep the invaders out.
