Benjamin Day

Introduction

Benjamin William Day is a 20-year-old former University of Worcester student who pleaded guilty to murdering Maria Saceanu, a 24-year-old Romanian sex worker, in a plastic-lined “kill room” he prepared at a rented Airbnb in Tividale in England’s West Midlands. A forensic science student who prosecutors said modeled the killing on the TV drama Dexter, Day stabbed Saceanu 78 times — many of the wounds inflicted after death — and was trying to dismember her body when he cut his left hand, a mistake that set off the chain of events leading to his arrest. He changed his plea to guilty on the second day of his murder trial at Wolverhampton Crown Court in October 2026 and faces a mandatory life sentence when he is sentenced on December 4.

Background Information

Day grew up in Redditch, Worcestershire, and enrolled at the University of Worcester, where he passed his first year studying journalism before transferring to a course in applied biology and forensics — a shift prosecutor Rachel Brand KC highlighted as one of the parallels with Dexter’s title character, a forensic scientist who is secretly a serial killer. He had come to know the Tividale area through his partner, whose family lived nearby. He was 19 at the time of the killing and turned 20 while awaiting trial.

On the evening of December 20, 2025, he texted Saceanu, who made her way by car to the Airbnb he had rented on Barncroft Road, arriving around 50 minutes later. Prosecutors said Day had been at the property since about 5:30 that afternoon preparing the room, and that he likely killed her within a very short time of her arrival.

The Controversy or Incident That Led to Their Cancellation

Convicted by his own plea. Day murdered Maria Saceanu on December 21, 2025, and admitted it — he pleaded guilty to murder at Wolverhampton Crown Court partway through his trial, two days after opening the case against him. No denial exists; his only dispute was self-defence, which his guilty plea abandoned. Sentencing is pending.

Prosecutor Rachel Brand KC told jurors Day spent several hours preparing the so-called kill room: he stapled plastic sheeting to the walls and covered the bed and floor, and brought knives, scissors, a canvas knife roll, a mask, an apron, disposable gloves, duct tape, a staple gun and cleaning chemicals. He changed into a khaki shirt like the one worn by the Dexter character before Saceanu arrived. The court heard there was no dispute from the defence that his fascination with the programme played a part in the killing; Brand listed further parallels including microscope slides containing blood thought to be a “trophy” from the killing, and said Day had been expected to claim self-defence by asserting he had set up the room only to film a Dexter “tribute” for TikTok.

A Home Office pathologist found 78 knife wounds on Saceanu’s body, many inflicted after death, and concluded she probably died from wounds to her neck damaging her carotid arteries or jugular veins; she also had defensive wounds to her hands. Day attempted to dismember her body but abandoned the task after cutting his left hand, placed her possessions into a black bin bag ready for disposal, and left the property around 12:30 a.m. on December 21. Having walked some distance away and disposed of a “burner” phone, he called 999 at 12:50 a.m. claiming he had been attacked by a wild dog or fox, and later texted the Airbnb’s landlord asking to extend his stay to a week.

Newly released police bodycam footage captured the arrest: bleeding from his hand wound, Day told officers “No, it’s just a wild dog. It just attacked me,” expressed relief that he still had four fingers, and could not remember where he had parked his car — which was outside the house containing his victim’s body. An officer told him his story didn’t check out, and Day was arrested on suspicion of murder at 3:42 a.m. as he lay on a hospital bed at Russells Hall Hospital in Dudley, around 80 minutes after the landlord reported blood on the stairs.

Public Reaction and Consequences

Detective Inspector Matt Marston, of the West Midlands Police Major Crime Team, said Day “planned this murder in meticulous detail” in “a pre-planned brutal attack on a defenceless woman lured to the room he had rented,” adding that “the details of this case shocked experienced officers.” Prosecutor Brand told jurors his actions “were those of a copycat, imitating the things he had seen” in the programme. Day initially denied murder, but after an hour-long delay on the trial’s second day he returned from the cells and, appearing to smirk, nodded towards the court clerk as he entered the guilty plea.

The case drew wide coverage in the British press and internationally for its Dexter parallels, and West Midlands Police released body-worn video of the arrest after his plea. Saceanu, who had been reported missing by her partner’s friend, was remembered by the detective as a heartbroken family’s loss.

Current Status

Day, of Yeadon Close, Redditch, has been remanded in custody since his arrest and pleaded guilty to murder at Wolverhampton Crown Court in October 2026. He faces a mandatory life sentence when he is sentenced on December 4, 2026; the judge will set the minimum term at that hearing. The bodycam footage of his arrest was released by police the day after the plea.

Impact on Their Career/Life

Day’s university career ended the night of the killing, and his trial’s early end — a two-week trial expected by the Crown collapsed into a plea on day two — capped a case prosecutors framed as a copycat crime conceived from a television drama. Where he might have worked in forensics, the field that fascinated him became the subject of the case against him, with the prosecution cataloguing how each step of his preparation mirrored the show he was obsessed with. He will spend a court-determined minimum behind bars before any release consideration.
