25 May 1990
According to Williamson’s HOLMES statement, some time after his last meeting with Worroll, he produced a “prepared descriptive report”, designated DP/141. A copy of this report was obtained from D&G.
It basically just repeats the 7 points listed by Worroll (see 24 May 1990 above) plus a couple of the other characteristics of the fragment mentioned by other experts. According to the label attached to the report, it was prepared on 25 May 1990.
