The unfinished chicken lunch was initially found in the SN. Numerous police first onto the scene corroborate this.
It was moved westward shortly after its discovery and the chicken placed inside the bag.
This places Williams in the SN window......exactly where Rowland testified.
Williams, Jarman and Norman all provided statements that claimed or implied that Williams ascended to the 5th floor together. This did not happen and they all recanted by the time of their testimony before the WC. The question is why did they feel the need to do so.
