No. Russians were around March 31, first video came out April 1.
All the surviving villagers are telling reporters the Russian soldiers took the men and executed them. Russians wouldn't allow relatives to bury them.
Satellite photos show bodies lying in the street March 19.
For example, Russian media outlet TV Zvezda claimed in an article published on the morning of April 1 that: “Airborne units, in cooperation with the Marines, successfully held back the actions of enemy forces in the direction of Gostomel – Bucha – Lakes for five days. As a result, the Marines were able to take full control of the territory from the Irpin River towards Kiev, with a total length of five kilometres.
“The commander of one of the Marine units Alexey Shabulin noted that currently Russian Marines conduct search and reconnaissance operations and clean up settlements with the further task of gaining a foothold in them”, the TV Zvezda article stated.
On the morning of April 1, meanwhile, a video was shared on Telegram featuring the secretary of the Bucha City Council, Taras Shapravsky, stating: “Currently, the city remains under occupation, many mines, houses and even corpses. Therefore, we ask those who remain not to approach dangerous objects. The liberation of the city continues, the Armed Forces of Ukraine, territorial defence are working to regain every metre of native land”.
Videos and photographs from Bucha, showing deceased individuals in civilian clothes, first appeared on social media channels on April 1.

Russia demanded the UN investigate right away. It was the UK which suddenly had other things to do. Strange that the side which supposedly did it is the side demanding a 3rd party investigate.
Also, why are the victims wearing white arm bands? Did the Russians kill their own supporters?
