15 June 1990
According to the FD-302 of Tom Thurman (FBI) that is provided with the police report, he
received K1 from Richard Sherrow of the Bureau of Alcohol Tobacco and Firearms Lab on this date.
This position is clearly inaccurate, as was discovered during the precognition process. In fact Sherrow gave the timer K1 to the CIA in late 1987 and it was in CIA possession until June 1990.
John Orkin of the CIA was the person who identified the similarity between PT/35(b) and K-l, not Thurman. There are further details of this in chapter 8 of the statement of reasons.
