Blood pressures: Interview with a [female] vampire

In a previous blog I briefly examined clinical vampirism as a sexual paraphilia. In that blog I noted that there had been very little empirical research on clinical vampirism and that most of what is known comes from clinical case studies. Furthermore, vampirism (i) is rarely a single clinical condition, (ii) may or may not be associated with other psychiatric and/or psychological disorders (e.g., severe psychopathy, schizophrenia, hysteria, mental retardation), and (iii) may or may not necessarily include sexual arousal. Other related conditions include odaxelagnia (deriving sexual pleasure from biting), haematolagnia (deriving sexual satisfaction from the drinking of blood), and haematophilia (deriving sexual satisfaction from blood in general), and auto-haemofetishism (i.e., deriving sexual pleasure from sight of blood drawn into a syringe during intravenous drug practice).

More recently I was contacted by a female ‘vampire’ (I use the term lightly in this instance) who has read my original article wanted to share her story with me. She gave me permission to disseminate her story with my blog readers on the understanding that I guaranteed her anonymity, confidentiality, and used her preferred name of ‘Countess Maria’ (CM) throughout the article. (She also signed herself as ‘The Young Madam’ but I will use CM for the remainder of this article). Obviously, I have no way of verifying anything that CM communicated to me, but on a personal level I have no reason to doubt the veracity of her claims. All of our communication was via email under her real name (which I then checked out online on a specific social networking site and I am 100% sure that she is who she says she is). She also said she “would be honored to have you feature my story.  I have answered your questions…as I honor your intellect and respect…being a professor is indeed a respectable, hardy, and challenging profession which is why I greatly respect an honor such profession”. More specifically, she added:

CM: “Whom I share this information must take it to the grave with them; except for you. You may share my story if and only if you use my name I have used for years ‘Countess Marie’. I do indeed consider myself a Countess due to what I have endured through humanitarian efforts as well as my ever strong want, need, and desire to help humanity – even if humanity shuns me for who I am”.

I asked CM for some socio-demographic information and she told me that she was 23 years of age, described herself as an African American and was currently employed as a Pharmacy Technician. Based on what she told me, she was well educated with various medical qualifications including Pharmacy Technician and Animal Care Certification. I also asked her about her religious beliefs and she responded: “Christian with great noble intent (‘I will gladly share my last piece of bread with my fellow man’). I live by that statement and I intend to follow through”. She also went ion to say: “I am finally in my studied job, as a Pharmacy Technician.  I have always had a thing for helping people…this is just one if the many ways I can help.  My dream in life is to be a great humanitarian and grow to greatness in helping those around me…I love who I am, and I am always wanting to follow my path.

In her account, CM didn’t really label herself a vampire but admitted that she liked drinking blood, and that many of the acts she engaged in would be labelled as vampire-like by others. She also talked about her first experiences of blood-sucking:

CM: “It is my understanding that you wish to hear about my further expansion on my clinical vampirism. Truthfully, I don’t really put a label on what it is I do. I have been consuming blood since I was young. The first cut I ever got was from a tree branch. I sucked my arm for several hours because the taste was delicious”.

At that point, CM didn’t really view her activity as in any way wrong but over time she began to realize that blood sucking was not considered normal behaviour and that she was socially ostracized by those who knew about her love of blood:

CM: “As I furthered in age through the years I noticed that I was considered different and odd, but I kept to myself about it. My love, my best friends, and you are the only people to know I consume blood…I would also like to add I have been called everything in the book for consuming blood; Monster, Demon, Grim’s Helper, and all the names in the middle…[Even] my friends called me [these things] at first because they did not understand what it mean for me”

However, CM went to great lengths to tell me that her love of blood did not involve the sucking of blood from other humans:

CM: “Make no mistake…I have never consumed blood from any human being – [only] myself. I consume pork blood, beef blood, and if that cannot be obtained I buy steaks and cook them very rare just enough for blood to spill out of it. I enjoy eating food, but it’s not really fun if it lacks in my nutrition. I add blood to juice, tea, desserts, cakes, salads, and disguise it in all sorts of ways”.

CM claimed she would never do anything that impacted on other humans and that morally it would be wrong to enforce her own beliefs and desires on others. She also believes that blood consumption is what keeps her alive:

“I never feed anyone else my blood food. I cook human food properly for guests for I know I am the only one who enjoys the taste of blood. To many, it is bitter and irony-metallic tasting. I cannot relate, due to the fact that for me, it tastes like fine wine. Without blood, I know that I would surely die. I need blood to live. I have always felt that way. Nothing on Earth will ever change my thoughts on the matter. I love blood…To me blood is life or death”.

CM also told me she had been diagnosed with anemia and I asked her whether believed that her love of blood may be because she has anemia:

“I will always love blood. I know that as far as my health goes, it actually favors blood consumption. I was told I almost died by slowly falling into a coma from sleeping for almost 4 straight days. The entire time I was asleep it only felt like seconds, but when I awoke, everyone was worried…I was diagnosed with being anemic, as well as hyperthyroidism. My hyperthyroidism is such [that] I will be on Levothyroxin until the day I die. My blood naturally lacks the iron (due to being anemic) so consuming blood helps me in many ways…I feel that my anemia further shows me that when I feel dizzy or “off centered” that I should consume blood.  I only consume pig or beef blood…NEVER human blood”.

As she had read my article clinical vampirism as a sexual paraphilia I also asked CM if her consuming of blood was in any way sexually motivate. She responded by saying:

“The sight of blood is a turn on for me, but only inside of a container.  If someone is bleeding of course I would help aid them and stop the pain.  If I see frozen blood in the grocery store or walk in the meat section at the market for too long, all I can smell is the blood, which causes arousal for me.  I don’t stay in butcher shops long for that reason”.

This suggests that blood for CM (in some circumstances) is sexually arousing and that there may be paraphilic elements in her reason for liking blood. Whether CM is typical of other ‘vampires’ is not clear. But given the little we know about people that love drinking blood, I am grateful to CM for her time in answering my questions and her honesty in relation to the development and motivations underpinning her hobby.

Token gestures: A brief look at ‘sexual trophy collecting’

Back in 2002, I had a little piece published on excessive collecting behaviour in the Guardian newspaper (‘Addicted to hoarding’). In it I wrote:

“I have always been interested in why we have what seems like an innate ability to collect. I would almost go as far as to say that we are ‘natural born hoarders’. Furthermore, there has been surprisingly little research in this area and Freud’s theories on the topic are unfortunately almost empirically untestable. I would also add that for some people, collecting is at the pathological end of the behavioural continuum. There are some that are (for want of a better word) ‘addicted’ to collecting and there are some with obsessive-compulsive disorders who simply cannot throw away anything”.

Since then I’ve published a few articles on the psychology of collecting in this blog and is probably one of the reasons that I have had a few approaches over the last couple months from journalists asking me about the psychology behind various forms of collecting. (In fact, I’ve also been approached to write an academic chapter on the phenomenon too). Two of the most recent media requests included journalists writing articles on why people collect retro video games (which I hope to write about in a future blog) and another on why people collect ‘sexual trophies’.

I have to admit that I am no expert on sexual trophies so I did a little reading on the topic. According to one definition I came across, a sexual trophy is “any item or piece of clothing gained from a sexual encounter as proof of a successful sexual conquest”. To tie in with the release of US comedy I Just Want My Pants Back, MTV conducted a [non-academic] survey and reported that one in three young British people (aged between 18 and 34 years) admitted to owning some sort of sex trophy with one in six of them (16%) claiming they had two or more sex-based trophies (a group that MTV termed ‘Sexual Magpies’).

However, when it comes to the collecting ‘sexual trophies’, I would argue that most academic research that I have come across on the topic relates to more criminal sexual deviance rather than day-to-day sexual encounters. For instance, in the 2010 book Serial Murderers and Their Victims, Dr. Eric Hickey described the case of man – who was a voyeur – from Georgia (US) that used to break into houses and steal women’s underwear. On his eventual arrest they found over 400 pairs of knickers that he had stolen. More disturbing are cases such as this excerpt from a story in the Daily Telegraph. This is arguably more typical of what I perceive to be sexual trophy hunters:

“A company manager and ‘pillar of the community’ has been exposed after 20 years as a serial sex attacker known as the Shoe Rapist. James Lloyd, 49, a long-standing Freemason who took the footwear of his victims as trophies, was finally caught through advances in DNA techniques. Police later found more than 100 pairs of stiletto shoes hidden behind a trap door at the printing works where he was employed… As well as taking their shoes, he often stole jewellery from the women, mainly in their teens and early 20s, between 1983 and 1986” (Daily Telegraph, July 18, 2006).

However, Dr. Hickey’s book describes even worse acts of sexual trophy collecting. He noted that many serial killers are “known for their habits of collecting trophies or souvenirs. Others have collected lingerie, shoes, hats, and other apparel”. A sizeable section of the book concentrates on the types of serial killers that are popular in the media (such as those that commit ‘lust murders‘) and are the subject of many Hollywood films such as the series of films with (my favourite fictional psychopath) Hannibal Lecter. As Hickey notes:

“These are the rapists who enjoy killing and, often, indulging in acts of sadism and perversion. These are the men who have engaged in necrophilia, cannibalism, and the drinking of victims’ blood. Some like to bite their victims; others enjoy trophy collecting – shoes, underwear, and body parts, such as hair clippings, feet, heads, fingers, breasts, and sexual organs…[and] evoke our disgust, horror, and fascination”.

One of the cases discussed is 1950s US serial killer Harvey Glatman (known in the media as ‘The Lonely Hearts Killer’) who used to take photographs of the women he murdered. Citing the work of Dr. Robert Keppel (another expert in serial murder cases and author of Serial Murder: Future Implications for Police Investigations), Dr. Hickey wrote:

“His photos were more than souvenirs, because in Glatman’s mind, they actually carried the power of his need for bondage and control. They showed the women in various poses: sitting up or lying down, hands always bound behind their backs, innocent looks on their faces, but with eyes wide with terror because they had guessed what was to come”.

Other murderers described by Dr. Hickey included a man that liked to surgically remove (and keep) the eyeballs from his sexual victims (most probably 1990s’ serial killer Charles Allbright) and another that skinned his victims and made lampshades, eating utensils, and clothing. In his overview of necrophilic homicide (i.e., those individuals that kill others in order to engage in sexual activity), Hickey also mentions that such necrosadistic murderers often engage in other paraphilias related to necrophilia “including partialism or the desire to collect specific body parts that the offenders finds sexually arousing. This may include feet, hands, hair, and heads, among others”. Hickey also noted that:

“Another important characteristic of these lust killers was the ‘perversion factor’. This subgroup was often prone to carry out bizarre sexual acts. These acts most commonly included necrophilia and trophy collection. Jerry Brudos severed the breasts of some of his victims and made epoxy molds. Brudos, like others, also photographed his victims in various poses, dressed and disrobed. The photos served as trophies and a stimulus to act out again”.

Later in the book, Dr. Hickey examines the case of Jerry Brudos in more detail (please be warned that some of the things written here may offend those of a sensitive nature):

“At an early age, Jerry Brudos developed a particular interest in women’s shoes, especially black, spike-heeled shoes. As he matured, his shoe fetish increasingly provided sexual arousal. At 17, he used a knife to assault a girl and force her to disrobe while he took pictures of her. For his crime he was incarcerated in a mental hospital for 9 months. His therapy uncovered his sexual fantasy for revenge against women, fantasies that included placing kidnapped girls into freezers so he could later arrange their stiff bodies in sexually explicit poses. He was evaluated as possessing a personality disorder but was not considered to be psychotic…He continued to collect women’s undergarments and shoes. Prior to his first murder, he had already assaulted four women and raped one of them. At age 28, Jerry was ready to start killing…He took [his first victim] to his garage, where he smashed her skull with a two-by-four. Before disposing of the body in a nearby river, he severed her left foot and placed it in his freezer. He often would amuse himself by dressing the foot in a spiked-heel shoe. His fantasy for greater sexual pleasure led him…to strangle [another victim] with a postal strap. After killing her, he had sexual intercourse with the corpse, then cut off the right breast and made an epoxy mold of the organ. Before dumping her body in the river, he took pictures of the corpse. Unable to satisfy his sexual fantasies and still in the grasp of violent urges, he found his third victim…After sexually assaulting her, he strangled her in his garage, amputated both breasts, again took pictures, and tossed her body into the river”.

Arguably the most infamous ‘sexual trophy collector’ was 1980s US serial killer Jeffrey Dahmer, the so-called ‘Milwaukee Cannibal’. In Dr. Hickey’s account he noted that:

“Restraining Dahmer, the officers looked around the apartment and counted at least 11 skulls (7 of them carefully boiled and cleaned) and a collection of bones, decomposed hands, and genitals. Three of the cleaned skulls had been spray-painted black and silver. These were to be part of the shrine fantasized by Dahmer. A complete skeleton suspended from a shower spigot and three skulls with holes drilled into them were found throughout the apartment…Chemicals, including muriatic acid, ethyl alcohol, chloroform, and formaldehyde, were also discovered, along with several Polaroid photographs of recently dismembered young men. A complete human head sat in the refrigerator”.

Another infamous case from the early 1970s (that I admit I had never heard of until I read Dr. Hickey’s book) was Ed Kemper, a cannibalistic killer who also collected human trophies and keepsakes of his victims. Citing the book Hunting Humans by Dr. Elliot Leyton, it was reported that:

“At the age of 23, Ed started killing again, a task that would last nearly a year and entail eight more victims. He shot, stabbed, and strangled them. All were strangers to him, and all were hitchhikers. He cannibalized at least two of his victims, slicing off parts of their legs and cooking the flesh in a macaroni casserole. He decapitated all of his victims and dissected most of them, saving body parts for sexual pleasure, sometimes storing heads in the refrigerator. Ed collected ‘keepsakes’ including teeth, skin, and hair from the victims. After killing a victim, he often engaged in sex with the corpse, even after it had been decapitated. In his confession Kemper stated five different reasons for his crimes. His themes centered on sexual urges, wanting to possess his victims, trophy hunting, a hatred for his mother, and revenge against an unjust society (Leyton, 1986)”.

The most obvious question related to these depraved acts is why such people do it in the first place. Writing in the Encyclopedia of Murder and Violent Crime, Nicole Mott provides an answer:

“A trophy is in essence a souvenir. In the context of violent behavior or murder, keeping a part of the victim as a trophy represents power over that individual. When the offender keeps this kind of souvenir, it serves as a way to preserve the memory of the victim and the experience of his or her death. The most common trophies for violent offenders are body parts but also include photographs of the crime scene and jewelry or clothing from the victim. Offenders use the trophies as memorabilia, but also to reenact their fantasies. They often masturbate or use the trophies as props in sexual acts. Their exaggerated fear of rejection is quelled in front of inanimate trophies. Ritualistic trophy taking, as is found with serial offenders, acts as a signature. A signature is similar to a modus operandi (a similar act ritualistically performed in virtually all crimes of one offender), yet it is an act that is not necessary to complete the crime”

In one of my previous blogs on the psychology of collecting more generally, I referred to a paper by Dr. Ruth Formanek in the Journal of Social Behavior and Personality. She suggested five common motivations for collecting: (i) extension of the self (e.g., acquiring knowledge, or in controlling one’s collection); (ii) social (finding, relating to, and sharing with, like-minded others); (iii) preserving history and creating a sense of continuity; (iv) financial investment; and (v), an addiction or compulsion. She also claimed that the commonality to all motivations to collect was a passion for the particular things collected. Personally, I think that the acquisition of sexual trophies – even in the most deranged individuals – can be placed within this motivational typology in that such individuals clearly have a passion for what they do and I would argue that the behaviour is an extension of the self that to some individuals may be a compulsion or addiction.

Dead famous: Jimmy Savile and the necrophilia allegations

(The following blog is based an article that that I was commissioned to write for a national British newspaper – The Independent – following the allegations that British television presenter, disc jockey and charity fundraiser Jimmy Savile had engaged in necrophilic practices. My original article was published on October 24 [2012] by The Independent and is reproduced here along with some of the references that my article was based on. My article was the most read blog of all The Independent’s blogs that week).

Recent reports about the sexual preferences of Jimmy Savile have not only thrown up allegations of paedophilia but have also hinted that he engaged in other sexual paraphilias such as necrophilia (having sex with corpses). Paraphilias (from the Greek and translating as “beyond usual or typical love”) are uncommon types of sexual expression and often more commonly described as sexual deviations, sexual perversions or disorders of sexual preference. Many of these behaviours may appear bizarre and/or socially unacceptable, and represent the extreme end of the sexual continuum. A number of published news reports on Savile all allege that he made unaccompanied visits to mortuaries (such as the one at Stoke Mandeville) and that he spoke publicly to the media about his “fascination” with dead bodies.

Some definitions of necrophilia make reference to “the erotic attraction to corpses” but that on its own doesn’t necessarily mean the person enjoys sex with a dead person. Necrophilia is very rare and there are no reliable estimates as to how prevalent the activity is. This is because the statistics are biased by those who get caught and/or end up seeking psychiatric help for the condition (in fact, all the knowledge we have about necrophilia comes from published case studies). The overwhelming majority of necrophiles are male (as are most paraphiliacs more generally) but there are occasional female cases (the most infamous being Karen Greenlee, the American who fell in love and kidnapped a dead male from a funeral home).

Given the paedophilic and necrophilic allegations against Savile, some members of the press have speculated whether there is an association between the two paraphilic behaviours. The scientific literature on necrophilia shows that it has close associations and overlaps with some sexual paraphilias including sexual sadism (sexual pleasure from hurting someone), sexual cannibalism (sexual pleasure from eating someone), vampirism (sexual pleasure from drinking someone’s blood) and erotophonophilia (sexual pleasure from murdering someone). However, there is little research showing any association between necrophilia and paedophilia except for those individuals that practice necropedophilia (sexual contact with the corpses of children).

Perhaps unsurprisingly, some types of occupation that have the easiest access to dead bodies are most likely to engage in necrophilic acts (the most obvious being gravediggers and mortuary attendants). However, there is some evidence that necrophiles seek out such jobs in the first place. In the largest published study of 122 necrophiles from all over the world, more than half (57%) were employed in a profession that gave them easy access to dead bodies. Such behaviour is also common among paedophiles that seek out jobs providing easy and/or unhindered access to children. Such claims have also been levelled at Savile surrounding allegations of both paedophilia and necrophilia.

One common reason given for why some people engage in such behaviour is the fact that corpses cannot refuse, reject or resist sex from a necrophile. Additionally, they cannot inform anyone (such as those in the criminal justice system) of its occurrence. Similar reasons have been applied to Savile in relation to choosing mentally ill and/or very vulnerable victims who (in essence) didn’t have a voice (or a voice that would be believed).

In 2011, Dr Anil Aggrawal of Maulana Azad Medical College (New Delhi, India) published the most in-depth academic and clinical account of necrophilia in his book Necrophilia: Forensic and Medico-legal Aspects. One of the most interesting observations is his claim that there are many different types of necrophile. Dr. Aggrawal claims there are ten different types of necrophile differentiated by the motivation and/or the type of sexual contact the necrophile has with the corpse. For instance, there are ‘homocidal necrophiles’ (so-called ‘necrosadists’, who will kill people just so as they can have sex with the dead) and ‘exclusive necrophile (who are psychologically and physiologically incapable of having sex with anyone living). In relation to the behaviour allegedly engaged in by Savile, he would most likely be classed as an ‘opportunistic necrophile’ (someone who engages in other types of sexual behaviour but would have sexual intercourse with a dead person if the opportunity arose).

Academic research has shown that two-thirds of the necrophiles say that their main reason for engaging in sex with corpses is the desire to possess an unresisting and unrejecting partner. The sadistic side of necrophilia has certainly been reported in some of the more extreme case studies but this appears to be rare, even among most cases of necrophilia. However, a recently published study by Michelle Stein (John Jay College of Criminal Justice, New York, USA) and colleagues examined 211 sexual homicides. Sixteen cases involved necrophilia (8%). Their findings suggest that the most common explanation for necrophilia (i.e., the offender’s desire to have an unresisting partner) may not always be applicable in cases where necrophilia is connected to sexual murder.
