Who was the first person in law enforcement to use the term "serial killer"?

Robert Restler and John Douglas FBI profiler's that started profiling

I would say it started with Jack the ripper. Jack the Ripper is a pseudonym given to an unidentified serial killer (or killers) active in the largely impoverished Whitechapel area and adjacent districts of London in the latter half of 1888. The name is taken from a letter to the Central News Agency by someone claiming to be the murderer, published at the time of the killings.

The legends surrounding the Ripper murders have become a combination of genuine historical research, conspiracy theory and folklore. The lack of a confirmed identity for the killer has allowed Ripperologists — the term used within the field for the authors, historians and amateur detectives who study the case — to accuse a wide variety of individuals of being the Ripper. Newspapers, whose circulation had been growing during this era, bestowed widespread and enduring notoriety on the killer due to the savagery of the attacks and the failure of the police in their attempts to capture the Ripper, sometimes missing the murderer at his crime scenes by mere minutes.

This got here approximately through fact the arresting police use to actual grab the guy by utilising the collar of the blouse. purely like the term "Cop" refers back to the copper badges the police wore.
