EXTRACT FROM CIA FILES
Tetraethyl Lead, the poisoner's poison. This could have been the poison used to kill the Somerton Man. Fast-acting and untraceable, the poison can be administered one drop at a time or in heavier concentrations. It kills quickly and efficiently and leaves no trace.
Does this mean the CIA had a hand in SMs death? Not necessarily but they certainly knew how.
These documents were found amongst the MK ULTRA and MK DELTA projects released under FOI in 1977.
Here's the link to the original document
And here's the link dating the existence of this known poison
Professor Stanford Hicks would not have known of its existence and specific use when he gave evidence at the inquest in 1949, this was top secret information that was originally released in Russia and then later the CIA made use of the technique.
Would this also explain the high concentration of lead found in the hair samples from SM?
Byron, your thoughts would be appreciated, I think you touched on this in the past somewhere.
