Not sure where you got this idea as the research on serial killers does not even remotely support this contention. In fact, research indicates that the mean IQ of serial killers is average to below average (see Eric Hickey, Serial Murders and their Victims, 2006).
Shadow- I was referring to the "organized variety" of serial killers, which I think by all accounts we would agree if that is who is responsible, their MO would match vs. disorganized- However, I meant 120+, not 160, so that was my error. My point was that I did not think the perp profile here is either disorganized or thoughtless as they poster indicated. Thanks for the correction.
Ted Bundy 120-140 depending upon who was testing
Michael Ross 122
Joel Rifkin 128
From Wiki:
Organized/Nonsocial Offenders are usually of high intelligence, have an above average
IQ (120+ range), and plan their crimes quite methodically, usually abducting victims, killing them in one place and disposing of them in another. They will often lure the victims with ploys appealing to their sense of sympathy. For example, Ted Bundy would put his arm in a fake plaster cast and ask women to help him carry something to his car, where he would beat them unconscious with a metal bar (e.g. a crowbar), and carry them away. Others specifically target prostitutes, who are likely to voluntarily go with a serial killer posing as a customer. They maintain a high degree of control over the crime scene, and usually have a solid knowledge of
forensic science that enables them to cover their tracks, such as by burying the body or weighing it down and sinking it in a river. They follow their crimes in the media carefully and often take pride in their actions, as if it were a grand project. The organized killer is usually socially adequate, has friends and lovers, and sometimes even a spouse and children. They are the type who, when captured, are most likely to be described by acquaintances as kind and unlikely to hurt anyone. Some serial killers go to lengths to make their crimes difficult to discover, such as falsifying
suicide notes, setting up others to take the blame for their crimes, and faking
gang warfare or natural deaths.
Coral Watts,
Ted Bundy, and
John Wayne Gacy are well-known examples of this type of serial killer.
