In 2018, the Offender Database recorded that 28-year-old Christopher Boon was jailed for life with a minimum term of 29 years for the murders of his wife and young stepdaughter. Boon—of Dexter Way, Gloucester, Gloucestershire—pleaded guilty at Bristol Crown Court to the killings of 31-year-old Laura Mortimer and 11-year-old Ella Dalby. It was reported that the investigation began in the early hours of 28 May 2018, when emergency services discovered the bodies of the mother and daughter lying side by side following a brutal domestic attack.
The investigation established that the murders occurred after Laura Mortimer informed Boon she wanted a divorce and had requested he leave their shared home within two weeks. Bristol Crown Court heard that Boon launched a sustained and savage episode of violence against his wife, inflicting 18 stab wounds. The prosecution reported that Ella Dalby, a student at Barnwood Park Arts College, heroically went to her mother’s aid during the assault, resulting in Boon turning his aggression toward the child and stabbing her 24 times.
Judicial Findings and Investigative Detail
The court reported that the attacks were of unspeakable savagery and that both victims suffered significantly before their deaths. Ms Justice May, presiding over the case, praised Ella as a brave girl who witnessed the murderous attack and died while trying to protect her mother. The investigation established that after committing the murders, Boon fled the property and confessed his actions to his mother, leading to his arrest by Gloucestershire Police shortly after the discovery of the scene.
Judge-led proceedings at Bristol Crown Court concluded with Boon receiving a life sentence. For his actions in Gloucester, Boon must serve at least 29 years before being considered for parole. The judge noted several aggravating factors, including the ferocity of the knife attacks and the fact that the murders were a response to the breakdown of the marriage. Laura Mortimer, who ran a wedding planning business called Sweet Beginnings, and her daughter Ella were described by family as being full of life and joy, a stark contrast to the violence that ended their lives.
Status and Statutory Requirements
For the records reported in Gloucestershire, the status of Christopher Boon as of April 7, 2026, was as follows:
- Custodial Status: SERVING (Life sentence; 29-year minimum term; sentenced 2018).
- Earliest Parole Eligibility: 2047 (Subject to Parole Board approval).
- Legal Status: CONVICTED (Double Murder).
- Judicial Oversight: Sentenced at Bristol Crown Court; investigated by Gloucestershire Police.

Monitoring and Public Protection
Boon is managed as a maximum-risk Category A prisoner within the high-security estate. Due to the nature of his conduct—specifically the “extreme violence” used against a child and the “premeditated cruelty” of the double homicide—his management is a critical priority for the Ministry of Justice. Authorities state that his history of domestic volatility, culminating in the slaughter of his family, identifies him as an individual who presents a permanent threat to the public.
As a convicted double murderer, Boon’s details are permanently logged on the national police database. Authorities state that should he ever be released after 2047, he will remain on licence for the remainder of his life. Any future residence or movement would be subject to the most stringent Multi-Agency Public Protection Arrangements (MAPPA). Any attempt to contact surviving family members or any breach of his life-licence conditions would result in immediate recall to prison to ensure the safety of the community from his demonstrated capacity for lethal violence.
QUESTION – Given that the offender murdered an 11-year-old child who was trying to save her mother, do you believe that “Whole Life Orders” should be mandatory for any individual who kills a child during a domestic violence incident?
