The Ministry - when they arrived - made it quick. First report was I think by 6 pm that day, that 84 bodies are found and all records/photos/taken, they are taken away by from the site.
The rest of the time they were looking for more, un-sure about the numbers. If you remember there was a controversy initially, no body could tell how many boarded the plane. Like ex-secretary of Lech Walensa felt un-well, and didn't go that morning. And closer to the night that day the bodies were already in Moscow; on the site they continued to look for more, taking ground layers off, for someone initially said in Poland can be whole 132.
