The report led to the suspension of Land Cabinet Secretary Charity Ngilu.
According to Mr Birundi’s affidavit, the records at the Ministry of Land show that Telesource Ltd is the registered proprietor of the land.
One of the key witnesses in the Sh8 billion Karen land case has died.
Former Deputy Chief Lands Registrar Geoffrey Birundi passed away last week.
Mr Birundi was the government official who did all the paperwork related to the Karen land.
He was among the senior officials mentioned in the Ethics and Anti-Corruption Commission report presented to President Uhuru Kenyatta.
The report led to the suspension of Land Cabinet Secretary Charity Ngilu, Sara Njuhi Mwenda, Pauline Wanjiku Gatimu, Mark Muigai Wanderi, Macmilan Mutinda Mutiso and James Mbaluka.
The six are facing charges of conspiracy to transfer the Karen land between 2005 and October 2014.
Mr Birundi was to testify in a case where city businessman Horatius Da Gama Rose, the owner of Muchanga Investments Limited, and a former National Social Security Fund (NSSF) managing trustee, Jos Konzolo, the owner of Telesource Ltd, are claiming ownership of the 134-acre land.
