Apparently one of Uchumi's buildings for sold for a song as well.
If a transparent process had been followed then there would be no question of impropriety but it was not.
So kirubi & kimunya are in the same boat. They may be innocent. They might not have benefited from the sale but it seems neither followed a transparent process.
kirubi is also known to have political goodwill/connections with the current government. I think he was at the head of kenatco - which collapsed during or soon after his time there - which is a pale shadow of it's former self.
