One similarity could be the physical description. If the true story involved a tall suspect, that would be carried over to the 'Tall Man' in the show. Also, the modus operandi might be similar, like the way the criminal approaches victims.
Well, first of all, the general profile of the criminal. If in the true story there was a tall man with certain behavioral traits, like being reclusive or having a particular pattern of movement in the areas where crimes were committed. In 'Criminal Minds', the 'Tall Man' might have those same or similar traits. Another similarity could be the type of victims. If the true story had a certain demographic as victims, the show might reflect that in the 'Tall Man' story as well. It's all about taking the essence of the real - life case and adapting it for the show's narrative.
The 'Tall Man' in Criminal Minds might share several similarities with the true story it's based on. For instance, the geographical location of the crimes could be similar. If the true story had crimes concentrated in a particular urban or rural area, the show might set the 'Tall Man' story in a comparable location. Additionally, the motives behind the crimes could be related. If the real - life case was driven by a sense of revenge or a need for power, the 'Tall Man' in the show might also exhibit similar motives. The show often tries to capture the psychological aspects of real - life criminals, so the 'Tall Man' may have the same or similar psychological makeup as the person in the true story, such as a lack of empathy or a distorted view of society.
