A Blast From the Past

It occurred to me this week, when 72–year–old Joseph James DeAngelo was arrested under suspicion of being the infamous Golden State Killer of the 1970s and 1980s, that it was a lot like when Dennis Rader was charged in another cold case, the BTK slayings in Kansas, in 2005.

Rader's crime spree started roughly the same time as the Golden State Killer's — in the mid–1970s. He continued a few years after the Golden State Killer's known attacks ended. (I say known because more facts may yet emerge as this case unfolds.)

Both men were regarded as a bit quirky — even menacing — by others; they held positions of authority and lived for many years in the communities they terrorized.

If DeAngelo turns out to be the Golden State Killer — he entered no plea when he appeared in court yesterday — he had a slightly higher body count. Of course, that doesn't include the roughly four dozen rapes or the more than 100 burglaries that have been tied to the Golden State Killer. That makes him a far more prolific criminal.

The men are roughly the same age — and had no reason to be concerned about DNA evidence at the time they committed their crimes since the development of that technology was still in the distant future. They knew enough about contemporary forensic evidence to avoid the evidentiary traps of the times, but DNA, which played a role in their eventual captures, was not on their radar.

DNA was discovered in the 19th century, but how to apply it to criminal investigations evolved well into the next century. In the '70s, high school science teachers could tell their students about DNA, but they couldn't say how it would influence law enforcement — or anything else — in the years ahead.

It would be a couple of decades before most people would get that kind of exposure via the O.J. Simpson trial — and even then DNA was misunderstood by many.

Neither man said much during the arraignment phase. DeAngelo confirmed his name when asked; Rader said nothing during his arraignment.

All serial killers are not created equal, though. While DeAngelo apparently has kept mostly silent since being taken into custody, Rader seemed to derive pleasure in letting the authorities know how clever he had been, confessing to crimes in addition to the ones with which he had been charged.

It all comes down to what motivates a serial killer, and they are as individual in their motivations as people in any other walk of life. For those who study serial killers, it will be instructive to learn what motivated DeAngelo.
