I had heard and read about a vicious killer named John Royster months before I actually saw him in person during his murder trial in New York City in the winter of 1997. I was shocked by how polite and gentle he seemed. His pleasant looks, neat clothes, slight build, and the braces on his teeth jolted me as his handcuffs were removed and he was seated at his defense counsel's table. Had I met Royster in Central Park and seen him flash his silver smile at me as I jogged by, I would not have felt the slightest breath of fear.
From June 4 through June 11, 1996, John Royster destroyed the lives of four women by grabbing them from behind, throwing them to the ground, and repeatedly smashing their heads against pavement, concrete, and cobblestone until he thought they were dead. He was cool and calculating enough to put down his knapsack and take off his coat before each assault. As his victims lay bleeding on the ground, battered beyond recognition, he raped them if he could. Then he calmly gathered up his belongings and left the scene. Bashing a woman's head to mush was sexually exciting to him, and he admitted to the police that he felt no remorse.
In the late 1880s, this sort of antisocial behavioral disorder - an insipid phrase - was diagnosed as "moral insanity," which ironically is a defense that recently has been tried in court. In his 1893 book on criminology, Arthur MacDonald defined what we would call a psychopath as a "pure murderer." These people are "honest," MacDonald writes, because they are not thieves "by nature" and many are "chaste in character." But all are "unconscious" of feeling "any repulsion" over their violent acts. As a rule, pure murderers begin to show "traces of a murderous tendency" when they are children.
Psychopaths can be male or female, child or adult. They are not always violent but they are always dangerous, because they have no respect for rules and no regard for any life but their own. Psychopaths have an x-factor unfamiliar if not incomprehensible to most of us, and at this writing no one is certain whether this x-factor is genetic, pathological (due to a head injury, for example), or caused by a spiritual depravity beyond our limited understanding. Ongoing research into the criminal brain is beginning to suggest that a psychopath's gray matter is not necessarily normal. In the general prison population of murderers, it has been shown that more than 80% of them were abused as children, and 50% of these offenders have frontal lobe abnormalities. The frontal lobe is the master control for civilized human behavior and is located, as its name implies, in the frontal part of the brain. Lesions, such as tumors or damage from a head injury, can turn a well-behaved person into a stranger with poor self-control and aggressive or violent tendencies. In the mid-1900s, severe antisocial behavior was remedied by the notorious prefrontal lobotomy, a procedure accomplished by surgery or by hammering an ice pick through the roof of an eye orbit to shear the wiring that connects the frontal part of the brain to the rest of it.
The psychopathic brain, however, cannot be wholly accounted for by traumatic childhoods and brain lesions. Studies using PET scans (positron emission tomography), which show images of the living brain at work, reveal that there is noticeably less neural activity in a psychopath's frontal lobe than there is in a "normal" person's. This suggests that the inhibitions and constraints that keep most of us from engaging in violent acts or giving in to murderous impulses do not register in the frontal lobe of the psychopathic brain. Thoughts and situations that would give most of us pause, cause distress or fear, and inhibit cruel, violent, or illegal impulses don't register in the psychopath's frontal lobe. That it is wrong to steal, rape, assault, lie, or do anything else that degrades, cheats, and dehumanizes others does not compute with the psychopath.
As much as 25% of the criminal population and as much as 4% of the entire population is psychopathic. The World Health Organization (WHO) now classifies "dissocial personality disorder" or antisocial personality disorder or sociopathy as a disease. Call it what you will, but psychopaths do not exhibit normal human feelings and are a small percentage of the population who are responsible for a large percentage of crime. These people are extraordinarily cunning and lead double lives. Those closest to them usually have no idea that behind the charming mask there is a monster who does not reveal himself until - as the Ripper did - right before he attacks.
Psychopaths are incapable of love. When they show what appears to be regret, sadness, or sorrow, these expressions are manipulative and originate from their own needs and not out of any genuine consideration for another creature. Psychopaths are often attractive, charismatic, and above average in intelligence. While they are given to impulse, they are organized in the planning and execution of their crimes. There is no cure. They cannot be rehabilitated or "preserved from criminal misadventure," as Francis Gallon, the father of fingerprint classification, wrote in 1883.
A psychopath often stalks his victims before contact, all the while engaging in violent fantasies. Psychopaths may go through dry runs to practice their modus operandi (MO) as they meticulously plan their actions in a manner that will insure success and evasion. Rehearsals can go on for years before the violent opening night, but no amount of practice or attention to strategy can guarantee that the performance will be flawless. Mistakes happen, especially on opening night, and when Jack the Ripper committed his first murder, he made an amateurish mistake.
Chapter Four. By Some Person Unknown
When Martha Tabran took her killer to the dark first-floor landing at 37 George Yard Buildings, he relinquished control to her and inadvertently introduced the risk that something could go wrong with his plan.
Her turf may not have been the killing ground he had in mind. Maybe something else happened that he did not anticipate, such as an insult, a taunt. Prostitutes, especially intoxicated old veterans, were not the sort to be sensitive, and all Martha had to do was reach between his legs and say, "Where is it, love?" Sickert used the term "impotent fury" in a letter. More than a century after the event, I can't re-create what actually happened in that pitch-black, fetid stairwell, but the killer got enraged. He lost control.
To stab someone thirty-nine times is overkill, and a frenzied overkill is usually prompted by an event or a word that sets off the killer in an unanticipated way. This observation neither suggests nor assumes that Martha's killer did not premeditate murder and fully intend to commit one, whether it was Martha Tabran's or whoever else happened to come along that night or early morning. When he accompanied Martha to the stairwell, he intended to stab her to death. He brought a strong, sharp knife or dagger to the scene, and he left with it. He may have been disguised as a soldier. He knew how to come and go undetected and to be careful about leaving obvious evidence - a lost button, a cap, a pencil. The two most personal forms of homicide are stabbing and strangulation. Both require the assailant to have physical contact with the victim. Shootings are less personal. Bashing in a person's head, especially from behind, is less personal.
Stabbing someone dozens of times is very personal. When cases like that come into the morgue, the police and the medical examiner routinely assume that the victim and assailant knew each other. It is unlikely that Martha knew her killer, but she elicited a very personal reaction from him when she did or said something that didn't follow his script. She may have resisted him. Martha was known for having fits and being quite difficult when she was drunk, and she had been drinking rum and ale earlier with Pearly Poll. Residents of George Yard Buildings later stated that they heard "nothing" at the early hour of Martha's death, but their testimony doesn't count for much when one considers the exhausted, inebriated condition of impoverished people who were accustomed to drunken behavior, scuffles, and violent domestic fights. It was best not to get involved. One could get hurt or in trouble with the police.
