This might not be relevent, but I heard from some retired police detective on coast to coast with George Noory that at any given time, there are several thousand serial killers running around amongst the US population. They tend to congretate along well travelled cooridoors (truckers) and often involve prostitution.
“at any given time, there are several thousand serial killers running around amongst the US population.”
Hard to say. I have studied the murder statistics, and it is possible. Successful serial killers are good at disposing of bodies. If the bodies are never found, the murder never registers on the crime reports. Prostitutes, because of the way they operate, are very vulnerable.
There may not even be a “missing person” report.
A successful serial killer will not target victims that draw attention to his actions.
It is not thousands, but possibly 10’s. If there were thousands of serial killers there wouldn’t be anybody left to kill
