Sorrell's report indicated they received "a near-to-scale depiction" from NESPIN. This depiction was apparently the basis for the drawings included in each of the witness files in the evidence package. These drawings are not the ones referred to in the three reenactments with church eyewitnesses performed in early December, since all of the drawings with dated signatures have the dates of their unrecorded March interviews by Sorrell's team. The drawings for the different witnesses have annotations indicating positions of the officers, themself, and the victim.
Neither the drawings nor the transcripts specify what point in time any of the annotated drawings represent. Several appear to superimpose the positions of people at different times.
Here is an example of a witness signed drawing apparently based on the "near-to-scale depiction".
Recently a map of the room appeared on Sorrell's website.
There is no indication of whether this was also produced by NESPIN.
