In November 2024, 21-year-old Phoenix Spencer Horn was murdered inside her flat on Glenn Lee street in East Kilbride, Scotland, by her 27-year-old live-in partner, Euan Methven. After nearly two years together, Phoenix had sought to end the relationship due to Methven's growing jealousy, volatility, and substance abuse. Shortly after midnight on November 17, 2024, Methven strangled and repeatedly stabbed Phoenix, inflicting a fatal chest wound before decapitating her body in the bathtub using kitchen knives. Over the next 48 hours, Methven remained in the flat with her remains, impersonated her via text messages to her mother, ordered drugs, drove her vehicle, and watched adult content on her phone over 170 times. On November 18, 2024, after Phoenix missed her work shift and police were contacted, Methven called 999 to report the murder. On June 17, 2025, Methven pleaded guilty at the High Court in Glasgow to murder and attempting to defeat the ends of justice, and on July 14, 2025, he was sentenced to life imprisonment with a minimum period of 23 years before parole eligibility.

Killer Postman Lives With Headless Lover For Days Before Discovery
Domestic Violence
The relationship followed a classic coercive control and domestic abuse pattern where early charm masked underlying misogynistic attitudes, substance dependency, and violent inclinations. As the victim sought independence and attempted to separate, the offender utilized manipulative excuses and substance abuse justifications before escalating to sudden lethality. The post-offense conduct demonstrated extreme detachment, victim devaluation, and active effort to delay discovery through deceptive communication.
Police responded to the Glenn Lee flat in East Kilbride on November 18, 2024, following a missing person concern raised by the victim's mother and a concurrent 999 call placed by Euan Methven. Methven confessed at the scene and on the emergency recording. Forensic analysis identified three bloodied kitchen knives, multiple facial stabs, and a fatal chest wound, alongside body decapitation in the bathroom. Digital forensics revealed Methven used the victim's phone to watch adult content over 170 times and impersonated her via SMS. Methven entered a guilty plea on June 17, 2025, at Glasgow High Court and received a life sentence with a 23-year minimum tariff on July 14, 2025.
Initial confusion was intentionally created by Euan Methven through deceptive text messages sent from the victim's phone to her mother, asserting she was simply sleeping off a hangover. Additionally, during initial post-arrest interviews, Methven attempted to attribute his actions to a drug-and-alcohol-induced blackout, which was refuted by digital and physical evidence showing deliberate, structured post-crime actions.
Reconstruction indicates that on the night of November 16, 2024, after sharing a meal, Methven attacked Phoenix shortly after midnight on November 17, strangling her and inflicting multiple knife wounds, including a fatal stab to the chest. He then moved her body to the bathtub and decapitated her with kitchen knives. For the next 36 to 48 hours, Methven engaged in substance use, used her phone to stream adult content, drove her car into town to purchase drugs, and forged messages to her mother before calling 999 as police arrived.
The case illustrates extreme lethality risks during relationship dissolution, particularly when an abusive partner exhibits severe jealousy, substance abuse, history of violent ideation, and acute control loss. The rapid escalation from emotional volatility to fatal violence without immediate prior physical warnings underscores the necessity of taking separation indicators and subtle emotional abuse seriously in domestic risk evaluations.
Key takeaways include the danger of social media masking severe domestic instability, the heightened lethality window during attempts to end a relationship, and the operational value of rapid digital forensic auditing (SMS timing and device usage) to dismantle false blackout defenses.
Early warning signs included Methven's history of online violent and misogynistic posts, subtle moodiness and criticism, possessiveness over Phoenix's clothing and social circle, and increasing reliance on cocaine, alcohol, and steroids as excuses for coercive behavior.
Key clues that exposed the crime included uncharacteristic, brief text replies from Phoenix's phone on Sunday morning, her failure to report to her work shift on Monday, and neighbor reports of loud noises and footsteps shortly after midnight on November 17.
The strongest evidence consisted of the crime scene recovery of three bloodied kitchen knives, digital forensic logs showing 170+ adult video streams on the victim's phone post-mortem, CCTV showing Methven driving the victim's Vauxhall Corsa, and Methven's recorded 999 confession.
Neighbors reported hearing loud noises and hurried footsteps overhead shortly after midnight on November 17, followed by total silence. Family members noted that Phoenix had expressed a desire to separate due to Methven's volatility and substance abuse.
Follow-up investigative reports disproved Methven's defense claim of an unremembered blackout by documenting deliberate, calculated behaviors across 48 hours, including drug acquisition, vehicular movement, and digital impersonation.
No major factual elements remain unresolved, as Methven confessed, pleaded guilty, and received a formal judicial sentence detailing his actions and timeline.
