Jack Johns

Introduction

Jack Johns is a 53-year-old man from the Tingley area of Leeds, England, who was sentenced to life imprisonment with a minimum term of 29 years for the murder of his fiancee, 51-year-old Malgorzata Wiktor, known to her family as Gosia. Johns killed Wiktor at her home in the Belle Isle area of Leeds on June 11, 2026, six months into their relationship, and pleaded guilty to her murder in September 2026. Sentencing him at Leeds Crown Court on November 9, 2026, Judge Tom Bayliss KC described Johns as an “obsessive, possessive, domineering and unstable individual” and told him directly: “You are, Jack Johns, an extremely dangerous man.” The hearing also revealed that Johns had changed his name from Colin French after previous convictions for violent offences against two former partners, in 2006 and 2016.

Background Information

Wiktor had moved to the United Kingdom from Poland about twenty years before her death, raising her son Gracjan and working as a receptionist at a dental practice. She met Johns and the pair became engaged within three months, a timeline she described in court as rushed and pressured, according to prosecutor Geraldine Kelly KC. Friends and family described Johns’s early behaviour toward her as “overwhelming” and characterised it as “love bombing,” and by the final weeks of her life Wiktor herself had raised concerns with her cousin about his over-the-top affection. She complained of feeling “suffocated” in the relationship, telling others that Johns was “too intense,” watched her when she texted other people, was overly emotional and too clingy, and complained about some of the clothes she wore. A colleague who remembered her as “loud and vibrant” before the relationship said she had become “quiet and sad.”

The Controversy or Incident That Led to Their Cancellation

Convicted and sentenced. Johns pleaded guilty to murdering his fiancee Malgorzata Wiktor at her Leeds home in June 2026 and was sentenced to life imprisonment with a minimum term of 29 years in November 2026.

On June 11, 2026, police were called to Wiktor’s home after colleagues raised the alarm with her son when she failed to arrive for work. She was pronounced dead at the scene, having suffered multiple skull fractures and stab wounds. Johns had refused to discuss the circumstances of her death, and Judge Bayliss told the court that the murder was “the culmination of a campaign of coercive and controlling behaviour,” adding that “the murder represented the final assertion of control.” The court heard the killing was the endpoint of a pattern the judge described as carrying the “classic markers of coercing and controlling behaviour,” and that in the days before her death Wiktor had sent a voice note complaining that Johns “wasn’t sharing his past.”

That past was extensive. The sentencing hearing was told Johns had been convicted of offences against two previous partners: he received an Imprisonment for Public Protection sentence for a 2006 offence of arson endangering life, having set fire to the home of an ex-girlfriend while she and her family were inside, and ten years later he attempted to kidnap another woman he had been in a relationship with after hiding in the boot of her car. His licence period for the latter offence ended in 2024. Judge Bayliss noted there were “number of strikingly similar circumstances” across the offences and said it was “unfortunate to say the least that an extremely dangerous man was in a position, under a new name, to start a relationship with this poor woman.”

Public Reaction and Consequences

Victim statements from Wiktor’s family were read at the sentencing hearing. Her son Gracjan described his mother as “the kindest, most loving and trusting person I have ever known,” saying “the most difficult part is that mum was taken away without warning and without the opportunity to say goodbye.” Her sister Anna said: “Something died in every one of us that day. He destroyed our family’s world. The consequences of this crime did not end on the day that Gosia died.” Detective Inspector Hannah Dixon, the senior investigating officer, said West Yorkshire Police had not been contacted about concerns over Johns before the killing, and acknowledged that Wiktor had considered contacting Johns’s ex-partners to discuss his behaviour.

Current Status

Johns, 53, is serving a life sentence and cannot be considered for release until he has served at least 29 years. He pleaded guilty to murder in September 2026, avoiding a trial, and was sentenced the following month at Leeds Crown Court. The judge’s sentencing remarks placed his case explicitly in the continuum of his two previous convictions for violence against partners, and police confirmed after the sentencing that no concerns about Johns had been reported to them during his relationship with Wiktor.

Impact on Their Career/Life

At 53, with a minimum term of 29 years, Johns will be in his eighties before he can even be considered for release, and the sentence was structured around the court’s finding that he is an extremely dangerous man whose pattern of partner violence spans two decades and two names. The case’s public significance for the wider domestic-abuse picture — the judge’s identification of “love bombing,” coercive control and escalating possessiveness as the visible markers in the months before a killing — was set out in open court through the prosecutor’s account of what Wiktor and her family had noticed. For Wiktor’s family in Leeds and in Poland, the sentence closed a case that began when she did not arrive for her shift at the dental practice on a June morning.
