Introduction
You enter a marriage hoping for lifelong security, but when betrayal strikes, the emotional fallout can shatter your sense of reality. Divorce often proves psychologically more torturous than death, as love, sex, and money transform into a deadly battlefield. You might find yourself trapped in a bitter dispute where obsession overtakes reason and normal conflict escalates into lethal violence.
Tammy Cohen investigates the dark psychology behind marital breakdowns and homicide in Deadly Divorces. The book reveals how vulnerability, financial panic, and controlling behaviour push ordinary people to commit murder when relationships end.
- What psychological triggers turn bitter divorces into homicide?
- How do financial fears and infidelity drive contract killings?
- Why do systemic failures allow controlling partners to issue fatal ultimatums?
1. Psychological Background and Marital Breakdown
Severe childhood trauma and vulnerability lay the groundwork for destructive relationship cycles when marriages fracture under the weight of infidelity.
Early Life and Marriage
Childhood neglect and abuse create deep-seated feelings of worthlessness and an extreme fear of abandonment. These old wounds resurface catastrophically during adult relationship crises.
Rena Salmon was born on 20 February 1960. She ran away from home at age 13 and spent her teenage years in care. Her mother subjected her and her sister to physical abuse and racial slurs because of her dark skin inherited from her Asian father.
Institutional structures can provide a vital sense of belonging for individuals lacking a stable upbringing. Joining the Army allowed Rena to wear a smart uniform and fit in. She trained as a Data Telecoms Operator and was posted to Northern Ireland in 1980, where she met Paul Salmon, a technician with the Royal Signals.
The Affair and Escalation
When an unhappy marriage deteriorates, the cycle of one partner pulling away while the other becomes clingy accelerates the collapse.
Paul Salmon earned £80,000 a year as an IT consultant. When Rena developed chronic back pain and weight gain, Paul grew distant. Rena tried to win him back by buying sexy underwear and washing and ironing his clothes while he openly saw Lorna Rodrigues.
The pain of infidelity is exponentially magnified when the affair involves a trusted close friend and neighbour. Lorna and Keith Rodrigues befriended the Salmons after moving to Great Shefford, providing Rena with her primary emotional support system before the betrayal destroyed it.
Geographical distance and attempts at reconciliation often fail to break the emotional addiction of an illicit affair. The Rodrigues family left for Australia in January 2002 to mend their marriage, but Lorna soon returned to the UK alone after telling Paul she found the right country with the wrong man.
Unchecked rage and emotional instability during a bitter divorce lead to erratic behavior, vandalism, and escalation. Paul moved out of the family house in June 2002. Rena engaged in heavy drinking, suicide threats, public assaults, and vandalism.
Rena scrawled the word whore down the side of Lorna's Saab. She attacked Paul and Lorna with a bunch of keys in front of her children. She also threatened various friends that she would shoot Lorna, though people around her dismissed these warnings as empty venting.
2. Preparation and Fatal Violence
Unresolved fury combined with unmonitored access to weapons and legal pressure can culminate in calculated murder.
The Path to Murder
Rena lied to a local locksmith by claiming her estranged husband had died in a car accident and that insurance papers were locked inside his weapons cabinet. The sympathetic locksmith opened the cabinet, granting Rena access to the double-barrelled Beretta she had previously bought Paul.
The Shooting of Lorna Stewart
On the eve of a court divorce hearing, Rena drove 60 miles to Lorna's beauty salon in Chiswick with a shotgun hidden in her car boot. After a brief, calm exchange with Lorna in the office, Rena shot her twice, subsequently confessing to emergency services and waiting at the scene.
On 10 September 2002, Rena Salmon shot Lorna Stewart at her Chiswick salon while bookkeeper Lindsey Rees was present, then smoked cigarettes and sent text messages to Paul and Leone Griffin while waiting for police. On 16 May 2003, Rena Salmon was found guilty and sentenced to life imprisonment.
3. Betrayal, Finance, and Contract Killings
Fear of financial ruin and impending divorce settlements frequently drive perpetrators to execute murder plots and flee across borders.
Motives and Escape
Adulterers are frequently surprised by how easily they can separate their secret life from their normal routine, allowing them to lie or act normally without obvious emotional betrayal. You see this capacity to compartmentalise when partners maintain affairs while living with their spouses, later giving tearful appeals while knowing their victims are already dead. Garry Malone managed to maintain an affair with Paula Fiddes while living with his wife Sharon, later giving a tearful televised appeal for Sharon's return while knowing she was already dead.
Impending divorce settlements and fear of financial ruin are major catalysts for lethal domestic violence. Garry Malone murdered his wife Sharon because he feared losing custody of his sons and facing financial disaster and poverty over her divorce settlement demands.
The Costa del Sol in Spain historically served as a haven for British fugitives attempting to escape legal consequences or debt. Due to historical legal loopholes concerning extradition treaties between Spain and the UK, the region attracted expats seeking to reinvent themselves or hide from law enforcement. After murdering his wife, Garry Malone withdrew £30,000, packed his sons into a rented van, and fled to the Costa del Sol under the alias Ralph Kirque.
Self-Funded Assassinations
Perpetrators of contract murders sometimes inadvertently finance their own executions using funds obtained from their victims. Killers can be hired using initial divorce payouts or shared marital assets, meaning the victim essentially bankrolls the plot against their own life. Yvette Luffman used a £1,000 down payment given to her by her ex-husband Simon as part of an informal divorce settlement to pay a bouncer named Thomas Convery to murder him.
Contract killers may alter agreed plans to minimize their own personal risk or operational exposure. Thomas Convery decided against killing Simon Luffman in his house and instead lured him to a disused section of the Nottingham Canal by inventing a fake drugs deal before shooting him four times.
The death of a parent late in life can trigger a severe identity crisis, causing older adults to abandon lifelong conservative roles. Following his mother's death at age 61, the 10th Earl of Shaftesbury ended a 24-year marriage, abandoned his estate duties over 9,000 acres in the Wimborne St Giles estate in Dorset, and embraced a hedonistic bar-hopping lifestyle on the French Riviera.
Wealthy, vulnerable individuals entering the underworld of high-end hostessing often mistake transactional companionship for genuine affection. The 10th Earl of Shaftesbury lavished millions on young models and hostesses, eventually marrying Jamila M’Barek, who later conspired with her brother to murder him over divorce finances.
4. Therapeutic Violations and Domestic Homicides
The dissolution of professional boundaries and the terror of losing a comfortable lifestyle can trigger fatal domestic attacks.
Therapeutic Boundary Violations
In 1972, 15-year-old Susan Bolling was sent to 40-year-old psychologist Dr Felix Polk for counselling after her parents divorced. Instead of a professional therapeutic bond, a mutual romantic passion developed, leading to a long-term clandestine relationship and eventually marriage despite a 25-year age gap.
After years of living in an upscale Orinda home, the Polks' marriage unravelled amidst mutual accusations of abuse, mental instability, and extreme delusions, culminating in bitter divorce proceedings and a battle for the house and custody of their youngest son Gabriel. Susan Polk accused her husband of being a Mossad agent and hiding millions in the Cayman Islands, while Felix barricaded himself in his room and filed for exclusive custody and home possession. This bitter dispute involved an 18-year marriage before buying their dream home valued at 1.85 million dollars. Court orders initially established a 6500 dollars monthly maintenance order, which was later drastically cut to a 1700 dollars monthly maintenance order while their youngest son Gabriel was age 14 at the time of separation.
On October 13, 2002, Susan Polk stabbed 70-year-old Felix Polk to death with a kitchen paring knife in the pool house of their Orinda compound after changing the locks on 10 October 2002. The attack left the victim with 27 total numbers of knife wounds sustained by Felix, including 5 serious knife wounds.
Spousal Murders and Confessions
During her 2006 murder trial, Susan Polk dismissed her appointed defense attorneys, including Daniel Horowitz, and chose to represent herself, enduring brutal testimony from her own sons before being convicted of second-degree murder. Susan Polk cross-examined her youngest son Gabriel for four days, while her son Adam testified against her and called her the embodiment of evil. The legal proceedings resulted in a 300000 dollars civil wrongful death case settlement amount and a minimum of 16 years of life imprisonment sentenced to Susan Polk in 2007.
Derek Symmons, a 62-year-old electrical engineer living in an exclusive Hertfordshire estate within the Loudwater estate where homes started at 1 million pounds, engaged in affairs beginning in 2004 while his wife grew resentful of his emotional bullying and impotence. Christine Symmons discovered her husband Derek's affair with internet-dating acquaintance Myra Croney after accidentally listening in on an intimate phone conversation.
The prospect of losing financial security and a comfortable lifestyle through divorce can trigger extreme violence in a controlling spouse. After 38 years of marriage, Christine consulted a solicitor for a divorce and demanded a trial separation. Fearing the loss of his high standard of living and assets, Derek attacked her during a violent row after a marriage counselling session on 5 September 2005, strangled her, and placed her body in the boot of his car. Derek Symmons wrapped Christine's body in plastic sheeting, loaded it into the boot of his BMW, and drove across the English Channel toward the south of France, arriving at the Hotel Mercure in France on 6 September 2005.
When checked into the Hotel Mercure near Macon, Derek Symmons approached the receptionist and confessed, stating he had killed his wife and her body was in the car boot. A jury at St Albans Crown Court took 3 hours to reach a verdict on 11 December 2006, when Derek Symmons was found guilty of murder.
5. Controlling Behaviour and Systemic Failures
Controlling partners who view spouses as personal property often issue lethal ultimatums, exploiting systemic law enforcement failures.
Asset Disputes and Ultimatums
Christopher Lumsden, suffering from a terminal muscle-wasting disorder and feeling abandoned by his wife Alison after she confessed to an affair with a family friend, experienced a sudden, overwhelming wave of rage while she sat at her dressing table and killed her with a kitchen knife.
Christopher Lumsden killed his wife Alison on 16 March 2005 at their home in Bowdon after she announced she wanted a divorce and was having an affair with Roger Flint. He was later cleared of murder but convicted of manslaughter on grounds of diminished responsibility and sentenced to five years in prison. At the time, Christopher Lumsden was 52 years old, facing an estimated survival time of 3 years from his diagnosis, and living in Oakleigh, the couple's stone-built mansion valued at 2m pounds.
The fear of losing property and assets built over a lifetime during a bitter divorce can drive a controlling partner to commit murder and conceal the body using livestock. Martin Baker was terrified that his estranged wife Tina would take half of Brookfield Farm or force its sale after she walked out and sought a divorce. Reminded of his previous threat to his first wife about feeding her to pigs, police suspected he murdered Tina on the farm and disposed of her remains.
Tina Baker disappeared on 8 July 2002 after leaving her boyfriend's home to go to the farm. Her body was never found, but Martin Baker was convicted of her murder in November 2006 and sentenced to life with a minimum term of 14 years. Brookfield Farm in Chobham, Surrey, spanned 14 acres and had a purchase price of 52,000 pounds, while Surrey Police offered a 10,000 pounds reward during the search.
Controlling partners who view spouses as personal property may issue lethal ultimatums and prepare premeditated wills and instructions before resorting to murder. Alan Pemberton left copies of his and Julia's wills and instructions on his study desk in their home in Old Hallowes at Slanting Hill, Berkshire, after Julia asked for a divorce on 3 September 2002, following 22 years of marriage and while the property was valued at 975,000 pounds.
Police Failings and Heroic Intervention
Perpetrators of domestic homicides often project an outwardly calm, jovial, or normal demeanor right up until the moment they execute their premeditated violence. On 18 November 2003, the afternoon before killing his family, Alan Pemberton played golf at a club with a 1,000 pounds annual fee, chatted cheerfully, and had a pint of cider at a local pub as if he were an ordinary businessman heading home.
Systemic failures by law enforcement to properly log evidence, respond promptly to emergency calls, and enforce restraining orders can leave domestic abuse victims as unprotected targets. Despite Julia Pemberton reporting death threats, having her locks superglued, and handing in a defaced affidavit containing explicit threats, police repeatedly failed to investigate or take action, and lost crucial paperwork, ultimately arriving at the scene 34 minutes after the 999 call.
Julia Pemberton was promised police would respond within 10 minutes to any silent 999 call, but when Alan Pemberton attacked the house on 18 November 2003, it took 24 minutes for unarmed officers to be dispatched and another 6 hours for armed backup to enter, during a harrowing emergency call lasting 16 minutes.
Children of victims may attempt to physically interpose themselves between an enraged parent and their intended victim, sometimes suffering fatal consequences. On 18 November 2003, Alan Pemberton shot his son Will twice in the chest when Will stepped outside to stop him, and then pumped three more shots into him before breaking into the house to murder Julia. Will Pemberton was 17 years old at the time of his death.
