In a popular way a killer is seen as a random, unidentifiable person who kills others almost for sport. It’s not straightforward to use a story by way of identification nor is it presented as needful for it. Why should we expect to know of a potential murderer down our street?
The facts of the matter are laid out in more detail elsewhere. It’s not possible to take all of it and make sense out of it in one full swing as if such a job should exist. A murderer in this instance is different to a murderer in another. It’s just the way it is.
A serial killer is different because he or she takes the law into their own hands and abuses it. They’re not seeking a chance meeting to make an opportunistic kill. They’re plotting one for their own benefit and they’ll make efforts to get to it.
The tracking of a serial killer is tight and dense labour. It takes a lot of effort, and can take decades to solve. Sometimes it stops it from happening and sometimes it doesn’t. The facts of the matter state that working on it helps support a broader picture as well.
