Dr. Killeen's belief that two weapons were used in Martha Tabran's murder was buttressed by a difference in the size of the stab wounds. However, this discrepancy can be accounted for if the blade was wider at the guard than it was at the tip. Stab wounds can be different widths depending on their depth, the twisting of the blade, and the elasticity of the tissue or the part of the body being penetrated. It is hard to ascertain what Dr. Killeen meant by a knife or a dagger, but a knife usually refers to a single-edged blade while a dagger is narrow and double-edged and has a pointed tip. The terms knife and dagger are often used as synonyms, as are the terms revolver and pistol.
As I was researching the Ripper cases, I explored the types of cutting instruments that might have been available to him. The variety and availability is bewildering, if not depressing. British travelers to Asia returned home with all sorts of souvenirs, some better suited than others for stabbing or cutting. The Indian pesh kabz is a fine example of a weapon that could leave wounds of several different widths, depending on their depth.
The strong steel blade of this "dagger," as it was called, could create an array of wounds that would perplex any medical examiner, even now.
The curved blade is almost an inch and a half wide at the ivory handle, and becomes double-edged two-thirds of the way up when it begins to taper off to a point as thin as a needle. The one I bought from an antiques dealer was made in 1830 and (including its sheath) would easily fit in one's waistband, boot, or deep coat pocket - or up a sleeve. The curved blade of the Oriental dagger called a djambia (circa 1840) would also leave wounds of different widths, although the entire blade is double-edged.
The Victorians enjoyed an abundance of beautiful weapons that were made for killing human beings and were cavalierly collected during travels abroad or bought for a bargain at bazaars. In one day, I discovered the following Victorian weapons at a London antiques fair and at the homes of two antiques dealers in Sussex: daggers, kukris, a dagger stick disguised to look like a polished tree branch, daggers disguised to look like canes, tiny six-shot revolvers designed to fit neatly into a gentleman's vest pocket or a lady's purse, "cut throat razors," Bowie-type knives, swords, rifles, and beautifully decorated truncheons, including a "Life Preserver" that is weighted with lead. When Jack the Ripper cruised for weapons, he was blessed with an embarrassment of riches.
No weapon was ever recovered in Martha Tabran's murder, and since Dr. Killeen's autopsy report seems to be missing - as are many records related to the Jack the Ripper case - all I had to go on were the sketchy details of the inquest. Of course I cannot determine with absolute certainty the weapon that took Martha's life, but I can speculate: Based on the frenzied attack and subsequent wounds, it may very well have been what the Victorians called a dagger - or a weapon with a strong blade, a sharp point, and a substantial handle designed to stab without the risk of the perpetrator's losing his grip and cutting himself.
If it is true that there were no defense injuries, such as cuts or bruises on Martha's hands or arms, their absence suggests she did not put up much of a struggle, even if her clothing was "disarrayed." Without more detail about exactly how her clothing was "disarrayed," I can't surmise whether she had begun to undress when she was attacked; whether the killer rearranged, undid, cut, or ripped her clothing; whether he did so before or after her death. In criminal cases of that era, clothing was important mainly for purposes of identifying the victim. It wasn't necessarily examined for tears, cuts, seminal fluid, or any other type of evidence. After the victim was identified, the clothing was usually tossed out the dead-house door into an alleyway. As the Ripper's victim count went up, some socially minded people thought it might be a good idea to collect the clothing of the dead and donate it to paupers.
In 1888, little was known about the behavior of blood. It has a character all its own and a behavior that dutifully abides by the laws of physics. It isn't like any other liquid, and when it is pumping at a high pressure through a person's arteries, it is not going to simply drip or slowly drain when one of those arteries is cut. At Martha's crime scene inside the stairwell, a high arterial spatter pattern on a wall would indicate that the stab wound to her neck severed an artery and occurred while she was standing and still had a blood pressure. An arterial pattern peaks and dips in rhythm with the heart and would also indicate whether a victim was on the ground when an artery was cut. The examination of the pattern helps establish the sequence of events during the attack. If a major artery is severed and there is no arterial spatter, in all likelihood other injuries have already just about extinguished the victim's life.
The stabbing and cutting wounds to Martha Tabran's genitals indicate a sexual component to the crime. Yet if it is true - as it seems to have been in all of the alleged Ripper murders - that there was no indication of "connection," as the Victorians called intercourse, then this is a pattern that should have been treated very seriously, but wasn't. I am not sure how a "connection" was determined. The problem with a prostitute is she may have "connected" numerous times in one night, and rarely if ever cleaned off the many levels of civilization she carried on her body.
Furthermore, body fluids could not be tested for blood type or DNA, nor was there any attempt to distinguish between human and animal blood in criminal investigations. Had there been evidence of recent sexual activity, the seminal fluid would have been of no forensic value. However, a consistent absence of seminal fluid or evidence of attempted intercourse - as is true in every Ripper murder - suggests that the killer did not engage in sexual activity with the victim before or after death. This pattern is not unheard of but it is uncommon with violent psychopaths, who may rape as they kill, climax as their victims die, or masturbate over the bodies after death. The lack of seminal fluid in the Ripper lust-murders is consistent with the supposition that Sickert was incapable of sex.
By modern standards, Martha Tabran's murder was investigated so poorly that it could hardly be called an investigation at all. Her murder did not excite the police or the press. There was virtually no public mention of her brutal slaying until the first inquest hearing on August 10th. There was little follow-up as time passed. Martha Tabran wasn't important to anyone in particular. It was assumed, as we used to say when I worked in the morgue, that she simply died the way she lived.
Her murder was savage, but it was not seen as the initial attack of an evil force that had invaded the Great Metropolis. Martha was a filthy worn-out whore and deliberately placed herself at great risk by the life she chose to live. She willingly plied a trade that required her to elude the police as much as her murderer did, it was pointed out in the press. It was hard to feel much pity for the likes of her, and public sentiment then was really no different from what it is now: The victim is to blame. Excuses in modern courtrooms are just as disheartening and infuriating. If she hadn't dressed that way; if he hadn't driven into that part of town; if she didn't go to bars looking for a man; I told her not to go jogging in that area of the park; what do you expect when you let your child walk home alone from the bus stop? As my mentor Dr. Marcella Fierro, chief medical examiner of Virginia, says, "A woman has a right to walk around naked and not be raped or murdered." Martha Tabran had a right to live.
