Sleepwalking Murders: To Kill While Asleep

Sleepwalking murders, also known as homicidal sleepwalking, describe the terrifying event that an individual awakes to discover they have murdered someone while sound asleep.  With no memory of their actions during their slumber, they are left in a dangerous position facing a murder charge with no defence. According to the London Sleep Centre, by 2005 there were 68 recorded cases of people who had killed someone while sound asleep. It is facts like these that make you look at your sleepwalking partner in a different light.

Sleepwalkers have been known to do some pretty strange things; cook, clean, iron…all without being consciously aware they are doing it and having no memory of it in the morning. There have been some cases of accidental death due to sleepwalking, where someone has wandered off inappropriately dressed, or staggered out into passing traffic, all while allegedly fast asleep. Sleepwalking murders account for, luckily, very few of these cases.

According to the National Sleep Foundation, between 1 – 15% of the general population sleepwalk on a regular basis. When we go to sleep, we go through various sleep stages ranging from light sleep to deep sleep and finally rapid eye movement (REM) sleep where we tend to dream.

Sleepwalking generally occurs in the phases of deep sleep just before we enter REM sleep where our limbs are temporarily paralyzed to stop us acting out our dreams. It appears that some people are prone to sleepwalking whereas others aren’t and research suggests episodes can be triggered by stress, lack of sleep, medication and substances such as alcohol.

Sleepwalking Murders

Also known as homicidal somnambulism, this occurrence is thankfully very rare. However, it has happened and a jury have had the task of deciding whether a murder committed while asleep means criminal responsibility for the unfortunate sleepwalker.

The sleepwalking state is often referred to as automatism meaning to be acting involuntarily, and this can either be due to mental ill-health (insane automatism) or external factors (non-insane automatism).

Take the court case of Jules Lowe, thought to be the first case of sleepwalking murders of its kind in the United Kingdom where an individual has been tried for murder with a sleepwalking defence. Mr Lowe was 32 years old and shared a house with his 83-year-old father. In 2003, his father was found dead in the driveway after suffering a brutal attack.

Jules Lowe: The First Sleepwalking Defence

Mr Lowe claimed to have no knowledge of what had happened to his father and how he had ended up dead on the driveway. With no other evidence to the contrary, he was charged with first degree murder.

His defence team called in sleep experts who carried out a number of tests to measure his brain waves, muscle and breathing activity and determined he did fit the profile of a sleepwalker. Furthermore, he had a history of sleepwalking although had never displayed any previous violence and by all accounts had an excellent relationship with his father. By this time, Mr Lowe had acknowledged he must have been responsible for the murder as no one else was present. It was determined he was in a state of automatism during the murder; that he was not conscious of his actions due to being asleep.

He was found not guilty of murder due to insane automatism, meaning he could not legally be held fully responsible for the fatal attack, and indefinitely sent to a psychiatric hospital.

Kenneth Parks: A Sleepwalking Killer?

The Kenneth Parks case provides one of the most curious recorded instances of sleepwalking murders. In the middle of the night in May 1997 in Toronto, Canada, 23-year-old Kenneth Parks got in his car and drove to his parents in laws home 14 miles away.  He stabbed his mother-in-law to death and assaulted his father-in-law who survived the attack.

Parks then drove to the police station and told them he thought he had killed people because there was blood on his hands. His defence team concluded he was sleepwalking at the time of the attacks. As in all other cases, he had a history of sleepwalking and he could not remember any details of the events.

The case report stated that Parks was in a state of non-insane automatism at the time with no previous history of mental ill-health. There was no evidence of psychosis and it was believed a number of factors combined that evening, including stress from his job and periods of insomnia running up to the events, a combination they claimed, extremely unlikely to ever occur again. In May 1988 he was found not guilty of the murder of his mother-in-law and acquitted of the attempted murder of his father-in-law.

Steven Steinberg: Murder While Sleepwalking

Steven Steinberg was accused of the murder of his wife Elena Steinberg by stabbing her 26 times in 1981, in Scottsdale, Arizona. Steinberg claimed he was sleepwalking and was not sane at the time of the murder.

Dr Martin Blinder, a California psychiatrist told the court the repeated stabbing of Elena was due to Steinberg being in a state of ‘dissociative reaction’. Steinberg was found not guilty due to sleepwalking at the time of the offence and he walked free from court. He did not deny killing his wife, but claimed the circumstances meant he was not responsible for the murder in a legal sense.

The jury believed the defence of sleepwalking at the time of the murder and therefore, although they knew he had committed the murder, they felt they had no choice but to find him not guilty as he was not consciously aware and rational when he carried it out. Steinberg initially told police an intruder had broken in and killed his wife and only claimed he was sleepwalking when police found evidence linking him to the murder. Although he was found not guilty on the basis of being insane at the time of the murder, he was deemed to be sane at the time of the trial  and therefore he was not sent to a psychiatric hospital.

Laws have now changed and since 1994 in Arizona cases such as this now mean the individual would have to serve a period of time in a mental institution. If this had been in the UK where sleepwalking murder is classed as an insane state, a period in a mental hospital would usually be the sentence implied, however this is not the case in the US and in Canada.

Sleeping Disorder – Automatism

The state of automatism has been named a number of times in cases where arousal from sleep has resulted in violence, questioning whether the individual had indeed aroused from sleep or were still sleeping. REM guitarist Peter Buck found himself in such a situation when he attacked a BA staff member on a flight into London in 2002.

Mr Buck had no memory of the attack and he was diagnosed as being in a state of non-insane automatism at the time due to the combination of a sleeping pill and alcohol before the flight took off. Sleepwalking is believed to be much more common in children with most growing out of the habit as they get older. Less than 1% of adults continue to sleepwalk in their adult life which is a much more reassuring statistic.

However, there have been cases of adults who do continue to sleepwalk and commit unthinkable acts while doing so. Non-insane automatism is defined as a criminal act committed by a sane person but without intent, malice or awareness and therefore they cannot be held criminally responsible for the act.

Scott Falater: The Sleepwalking Murders Defence

Probably the most complicated sleepwalking defence case to date is that of Scott Falater. In 1997, Mr Falater was 43 years old and found himself accused of murdering his wife. His horrified neighbour saw him put on a pair of gloves and proceed to roll his battered wife into the swimming pool of his home and hold her head under the water.

When the police arrived they found Mrs Falater dead in the pool with 44 stab wounds and Mr Falater in his pyjamas, oblivious to what had happened and rather confused as to why there were police all over his backyard. After an extensive police interview where Mr Falater was told of the fate of his wife, he could offer no explanation to what had happened. Like Lowe and Steinberg, Falater acknowledged he must have committed the murder but claimed he had no memory of it. During a search of the property, police found Mr Falater’s bloody clothes and shoes and the murder weapon in the spare tire well of his car.

Homicidal Sleepwalking or Cold-Blooded Murder?

During his trial for first degree murder, the defence claimed Falater was in a period of little sleep due to stress at his job and on the day in question he had removed all the tools from the spare tire space in his car, including the knife that was used in the murder, to fix a faulty pump in the pool.

They said he did not complete the job and went to bed exhausted. When he rose he was sleepwalking and returned to the pool to continue the task, flying into a rage when he was interrupted by his wife. They claimed his illogical actions were typical of someone who was sleepwalking. Sleep disorder expert, Dr Rosalind Cartwright, who examined Falater and said it was possible he was sleepwalking at the time of the murder. The prosecution claimed the sleepwalking defence was a fabrication by Falater who cover up his crime stating that his change of clothes and the placing of them with the murder weapon in a container in his car did not support a sleepwalking claim. They maintained that his actions were too complex to have been carried out while asleep.

In June 1999, Mr Falater was convicted of first degree murder and in January 2000 was sentenced to life imprisonment with no chance of parole.

“You try to make sense of his actions, the sequence of events. It’s off-center. Trying to hide her body in the pool with the lights on? He’s technically guilty, but he’s morally innocent. He was there, and he wasn’t there.” – Falater’s Mother

Although rare, some expects have expressed concern that this type of defence may become more common. Disproving a case of homicidal sleepwalking, as the time of the act has passed, can be very difficult. Sleep monitoring tests can indicate whether someone is prone to sleepwalking. Add that to a history of sleepwalking and you could end up with a reasonable defence for murder. Homicidal sleepwalking is a scary thought, not only for potential victims of such an act but for a sleepwalker who may wake up to untold horror at their own hands. Sleeping, it seems, is much more dangerous than we previously thought.

  • whoazh this blog is magnificent i really likke studying yyour posts.
    Keep up the ood work! You understand, a lot of persons are searching aroujd for this information, you could help them greatly.

  • Can I jusxt say what a comfort to discover an individual who genuinely understands what they aree talking
    about on the web. You certainly realize hhow to
    bring a problem to light and make it important.
    A lott more people must read this and nderstand this side of your story.
    I was surprised that you are not more popular because you surely possess
    the gift.

  • Hmmm, although i am an innate supporter of emperical scientific faculties , in the matters of law, i am also aware the dire shortcomings of its , if i must say it, its inborn innocent ways. Medical jurisprudence today, although granted a vital role in our court rooms, but still IS only an another step towards , while seeking the justice an another exhibit, to the evidence of crime. Law of evidence , still is more inclined to its own pseudo-scientific instruments, its own methods of detection and judgement and gives lesser heed towards the burrowed subjects of the proper scientific. The reason behind is ofcoarse is two and along with it, pshycology is peculiarly known a tad more to the men of law than those who deals in the science of a man's mind(most controversial, but known more to the lawyers in a sence that they often manipulate the flexible definations of pshycology in their own favour😉 and but not known at all as a wholesome subject, hope i made myself clear here 😯).

    The two reasons are 1) the cunning of the criminals 2) the more cunning of the lawyers ;).

    The dominant subject of our times, Science, is 'innocent', because it seeks by all its Heart and Consiousness, 'truth and truth only',the subject is Intelligent and is made Self-Aware, it changes its course rapidly, it does not abide by the complexities of human societies, it HAS an innate brain which thinks and is Devoid of innate sanctions,it mends its ways through clinical, labotorial research to thrive on precision of its subjects; actualy is lonely, only thinks of itself and betters itself, only know how to improve, only listen to its own ways and Will do anything to achieve it, potently a Hypoyhetical Sociopath of a subject to its behaivours and definations, as for the outside world or the world effected by it( as a bonus in a hypothetical measurement), it can only measure but can not derive, the subject has feeings ofcoarse but only for itself,pristinely selfish, does not abide by anything, All its organs exists for itself and itself only, A blue eyed cruel criminal. For law, has two faces,( all of 'them' have it, but the distinction is more here, is a world actualy) one the Theoretical, another the Applied. Applied or the Sanctioned law, its condition is more severe than that of the Science, Science is organic, a Human after all because it is the human which can only be of sociopath, as for the Applied Law It is actualy
    A Superior Non-Intelligent Robot, Unlike science it does not have a conciousness, it only follows the commands( sections of laws) which are inputed in it, the contradictions, dialectictics, counter-challenges are there, but they are all mechanical because Applied laws cannot think ! Not allowed to think beyond the mentioned ramblings of the sanctioned sections of the acts of law. It is entire mechanical and is a machine. And therefore, As an non-inteligent, self-Unaware, entity, it can be manipulated and is often manipulated, by the ways of the criminals or by the cunning of the lawyers, using the very instruments of Innocent science, which are actualy for justice, but used by them, turnig the very philosophy, as instruments of injustice and foul play.hahahahahahaha.Applied laws does not have any sences, but only commands, only a lesser 2nd hand substitute to the Theoretical law.

    This sciences of 'Sleep walking Murder' are potent, but should not be given a clear hand, there are windows, large windows for the Agents of Crime to manipulate the science here through Sanctioned laws actualy, where defence mechanism of a Defence lawyer can find save heaven for MURDER( WHICH IS DIFFERENT FROM HOMICIDE), by using the very same 'Criminal Responsibity' provisions, as a cunning 'legal excuse' ,as under the Criminal laws………

  • Hi Dev, thank you for your in depth and insightful comments. Science and law, two very different areas but two which overlap and meet each other within the courtroom.

    An area such as sleepwalking murder I think is complex. There is no doubt the individual committed the murder but proving whether or not they were asleep at the time is a difficult matter, and this of course is the key to criminal responsibility. A good lawyer can cast doubt on both sides and use science on both sides to help their case. The acceptance of the notion that a person can commit a murder while asleep and have no conscious knowledge of their actions needs to be gained if any individual is going to avoid a lengthy jail sentence and a clear conviction for murder. Furthermore you raise an interesting point regarding the difference between murder and homicide. Malicious intent is also a factor, whether someone was asleep or whether they were awake.

  • Great blog right here! Additionally your web site so much up fast!
    What host are you the use of? Can I get your associate link in your host?
    I wish my website loaded up as quickly as yours lol

  • A fascinating article! Some of the issues in these cases are so complex. It’s one thing to prove that a defendant is a sleepwalker, but another to prove that he or she was actually asleep at the time of the killing. Anyone can say, after the fact, they were asleep. Looking for corroborating evidence must be a major part of the defense attorney’s job.

    But underneath all these cases bubbles one terrifying fact: These things really do happen, and when they do, the experience for both victim and offender must be horrifying.

  • Thank you Ann Marie, I am glad you enjoyed the article! I have to say sleepwalking murder has intrigued and fascinated me for years. The concept that our minds could be essentially unconscious yet we could carry out such complex and horrific acts. It is quite a terrifying thought that while asleep you could do such harm to another. In some cases it really does appear that the person has no recollection of the acts and were as shocked as everyone else when the awoke to discover what they had done. The legal side in such cases must be more than challenging. How do you decide the level of someone’s criminal responsibility when they have committed the crime but claim no memory and if truely in a state of automatism had no conscious control over their actions? That is not a jury trial I would like to be sitting on!

  • I think that the majority of us totally underestimate just how vital sleep actually is. We depend on a restful sleep cycle in order to rejuvenate our cells, grow muscle, and repair damaged tissue – along with countless other processes. Plus, anyone that has even once had to deal with a night of poor sleep knows exactly how challenging it can be to wake up bright and early, get a move on with your day, and have the ability to to focus on the work or other responsibilities you have to concentrate on. During the process of conducting research for a recent article, I discovered that the CDC has presented reports claiming that 1 in 3 adults do not sleep anywhere near as well as they ought to. It’s horrible how bad we’re harming ourselves when we don’t get enough quality shut-eye.
