All serial killers are organized/disorganized

(or there are distinct types of serial killers)

• Developed by the FBI in the late 70s• Suffers from the Hollywood effect

If these are distinct types, we should be able to plot them out and see the differences!

Smallest Space Analysis (Multidimensional Scaling)

Plot characteristics to see patterns:

For example: Republicans and Democrats in the House have clearly different voting patterns

“All serial killers are likely to exhibit some aspects that are organized and some that are disorganized, but the differences between them are, more than likely, differences in the particular subset of disorganized variables that they exhibit.”

Serial killers select victims who somehow resemble their mothers

Tend to select vulnerable victims

Most serial killers don’t stick to one particular type of victim.

Most victims are people in the wrong place at the wrong time.
