One also has to consider the street lighting for these different locations, poor lighting will affect witnesses descriptions and cause problems in identifying who was who
Where were the street lamps situated in relation to where the witnesses were positioned, and were they all working, how far were the witnesses away from the persons they were referring to?
It seems this information was not obtained by the police as part of the investigation. That is why there is now a problem with assessing and evaluating the witness statements
I have mentioned a stated legal case previously which not only refers to the identification of suspects but is also used in determining the accuracy of witness testimony a pneumonic is used ADVOKATE R Turnbull 1976
Amount of time under observation: How long did the witness have the person/incident in view?
Distance: What was the distance between the witness and the person/incident?
Visibility: What was the visibility at the time? Factors include the time of day/night, street lighting, etc.
Obstruction: Were there any obstructions to the view of the witness?
Known or seen before: Did the witness know, or had the witness ever seen, the person before? If so where and when?
Any reason to remember: Did the witness have any special reason for remembering the person/incident? Was there something specific that made the person/incident memorable?
Time-lapse: How long has elapsed since the witness saw the person/incident?
Error discrepancy: Are there any errors or material discrepancies between descriptions in the first and subsequent accounts of the witness?
