March 31st. Russian forces leave Bucha.

April 1: Bucha’s mayor happily announces that the Russian army is gone from the city. Not a word about the corpses.

April 2: Ukrainian journalists drive and walk around the city. Another one. Not a word about the corpses.

Then:

Special Forces Regiment SAFARI Begins Clearing Operation in Bucha from Saboteurs and Accomplices of Russia - National Police

And only on April 3 do they finally find corpses in the middle of the central street. Magical.
