The arrest of a Pennsylvania man on charges of grave robbing this week has led to hundreds of news outlets reporting the horrific details of his collection of hundred of bones and several skulls. Much like Ed Gein before him, Jonathan Christ Gerlach (yes, that’s his middle name) raided, at the very least, Mount Moriah Cemetery on the border of southwest Philadelphia — for purposes, at this time, unknown. Like Gein, was Gerlach a necrophiliac? Was he on his way to becoming a serial killer? Or was he, as some have suggested (based upon his being tagged in Facebook group about the sale of human remains) more interested in the money that can be had from “the bone trade” as it is sometimes called (oh, and he stole jewelry, too).

The history of grave robbing is fascinating, albeit gruesome, stretching back into antiquity. Ancient Egyptians were known to rob the tombs of the wealthy. In fact, most tombs in Egypt’s Valley of the Kings were robbed within one hundred years of their sealing. But theft was not the only motivation for those who disturbed graves. In China, for example,  in 506 BC, military general Wu Zixu dug up the corpse of King Ping of Chu to abuse and whip his corpse. Desecration, and the fear and revulsion that came with it, gave the abuser a sense of power over the living AND the dead.

The first known case of what is otherwise called “body snatching” was committed in 1319 by four medical students in Bologna, Italy. For centuries following — most notably the nineteenth century with the infamous duo of Burke and Hare active in the 1820s — grave robbers illegally sold human remains to medical schools primarily for purposes of teaching anatomy. Many doctors believed it to be a necessary evil. These body snatchers came to be known as “ressurectionists,” and many were paid handsomely for their ability to supply cadavers (with no questions asked as to how they were obtained). They would send spies to funerals  to scout out the freshest bodies that would later be easily removed from the loose, newly disturbed ground. Some, like Burke and Hare, would even kill to get bodies, making the job all that much easier.

Iron coffins, grave alarms, and mortsafes (the iron cage around a grave) became common as a way to combat body snatchers. In the UK, the problem was so prevalent that the government issued the Anatomy Act in 1832, making grave robbing a criminal offense. Of course, the practice didn’t stop. And to this day, there’s a black market for bones, skulls, scalps, skin, teeth — you name it. Not for medical schools, but for private collections… even sexual gratification. Morbid obsession. Anti-social urges.

At “oddities” flea markets, conventions and the like, one can actually find and buy a human skull. They are often accompanied by a certification of some kind stating that the skull was obtained by legal means (e.g., a museum auction for deaccessioned pieces). But these are relatively few and far between, whereas availability on the black market / dark web / and even — as was apparently the case with Gerlach — social media groups, is prevalent.

Psychologists say the motivations for grave robbing vary. But at the root is a need for power and control. Thieves feel empowerment when they take from the dead, justifying their crimes as having no real victim, or seeing the theft as revenge for perceived injustice (“eat the rich”). Sociopaths find an outlet for anti-social behavior, whether its extreme vandalism, an inability to relate to the living, or an obsession with the dead and all things related to death. And psychopaths? They satisfy unspeakable urges. Some, like Ed Gein, go on to murder.

What were Gerlach’s motivations? The truth will come out in time. The details will be horrific. We will be further shocked by this man’s behavior. Perhaps what is most disturbing is that the reasons behind crimes like Gerlach’s are impossible to fully understand. But it gave him an identity in a subculture that exists at the fringes of polite society.

And that this subculture even exists is perhaps the most disturbing revelation of them all.
