The source of a letter that ‘exposed’ plot to assassinate Deputy President William Ruto remains unknown, a Nairobi court heard on Tuesday.
The lead investigator Chief Inspector Peter Maina on Tuesday told court that a forensic audit of the document failed to establish when the fake letter first emerged.
While testifying against Secretary of Digital Media at State House Dennis Itumbi and Mr Samuel Gateri, the investigator also confirmed to court that the forensic analysis was unable to trace originator of the letter.
The 20-pages forensic report produced in court as exhibit by the prosecution did not indicate when the image of the letter was first posted in a WhatsApp group named Tangatanga Movement.
“The forensic audit was to find the originator and author of the letter,” Mr Maina told Milimani Chief Magistrate Martha Mutuku.
