John Douglas pioneered behavioral profiling for the FBI.

He and others developed the investigative tool from over 25 years of interviews with convicted killers, arsonists, rapists, and bombers.

When someone asks your profile, what they're looking for are characteristics, which includes gender, includes age, race,

sometimes body typing, educational level, occupational type.

To determine these characteristics,

the profiler attempts to think like the killer.

He tries to uncover his motivations.

Examining every aspect of a crime reveals patterns of behavior.

What emerges is a profile describing the type of person the killer will most likely be.

After scrutinizing every detail of Sherry's abduction, Douglas generated a 22-point profile of the suspect.

He painted the abductor as a white male in his late 20s to early 30s, with

above average intelligence. He would most likely work as a blue-collar day laborer. Because

it sounded as if the killer had electronically distorted his voice, he probably worked

in electrical contracting. He would have a prior criminal record.

Douglas also suggested he lived locally. The tone and content of his phone calls indicated he was

an asocial obsessive compulsive. If the stress of everyday life became too great, he would break down. He would then feel

compelled to compensate for his own inadequacies through violent actions. He's a type of guy that

feels like one grain of sand on a beach where there are billions and billions of grains of sand.

He feels like nothing. He feels like a nobody.

And how can there's nobody, this personality, this person who's probably overweight, low self-esteem,

doesn't, unattractive, how can he become a somebody?

He'll go after victims that there was no chance
