Imagine no DNA technology. The first case adjudicated in the United States in which DNA evidence was presented was in 1987, and the science was considered controversial still for years after that. That’s hard to grasp today, in the days of the CSI effect, when juries expect DNA evidence and are often reluctant to convict without it.

In 1985, fingerprint examples were still matched by the human eye.

Now, I am by no means gifted in the technological sense. If it had been left up to me to harness electricity, we would all still be reading by oil lamps. I have no clue how my computer works. I still haven’t figured out how all those tiny little people get inside my television.

And yet, compared with the 1985 Tami, I am a technology junkie. I am never without my iPhone or iPod. “Have laptop, will travel” is my motto. My DVR records every rerun of House. I even occasionally tweet on Twitter.

So, used to all this modern convenience, I found it a major inconvenience when I couldn’t have my detectives jump on the information superhighway to gather information. And no cell phones for instant contact? How did we live?

In fact, criminal profiling-so commonly used today and so familiar to law enforcement and civilians alike-was still something of a fledgling science in the mid-eighties. That was what we think of now as the golden age of the FBI’s Behavioral Sciences Unit. Those were the days of the Nine: nine legends in the making (Conrad Hassel, Larry Monroe, Roger Depue, Howard Teten, Pat Mullany, Roy Hazelwood, Dick Ault, Robert Ressler, and John Douglas) who came together in three or four different groups over that time span to bring profiling and the BSU to the forefront of law enforcement.

In 1985, the unit was housed at the FBI Academy in Quantico, Virginia, in offices sixty feet belowground-ten times deeper than the dead-in what agents referred to as the National Cellar for the Analysis of Violent Crime.
