Serial killers have been a part of terrifying stories and bizarre myths that have made it across generations. While some serial killers were never identified, many became part of pop culture for their actions and motivations.
No one can deny that serial killers have always aroused a lot of interest among people and investigators have tried to come up with personality traits as well as behavioural patterns to identify them.
Among other signs, here are occupations that can indicate the likelihood of a person being a dreadful killer, according to criminologist Michael Arntfield.
Among skilled occupations, aircraft assemblers, shoemakers and car upholsterers may have murderous tendencies.
Forestry workers, Truck drivers and warehouse managers also make it to the list of people you need to be careful about, along with General labourers, hotel porters and gas station attendants.
Meanwhile it may come as a surprise that police and military personnel in addition to religious officials are also likely to be serial killers on the prowl.
While you never know who might turn out to be a murderer, this information may help keep dreadful murderers at bay.
