In 2020, Duncan Johnson, of Kelday Close, Kirkby, was jailed for a total of nine years after carrying out a predatory series of assaults against a mother and her seven-year-old daughter. The investigation established that on 15 March 2020, Johnson targeted Natalie Grimes at an Asda in the Walton area of Liverpool. The prosecution reported at Liverpool Crown Court that Johnson grabbed Ms Grimes by the throat and held a blade over her head moments after she had placed her child in the car, identifying a total abandonment of human decency.
The investigation established that Johnson’s series of behaviour was driven by a violent intent to seize the vehicle with the child inside. The prosecution reported that Johnson screamed, “I will f***ing kill you,” and brought the knife down, slashing Ms Grimes’ coat as she raised her arm to protect herself. This identifies a calculated series of assaults on the life-safety of the family, as the mother refused to surrender her keys, fearing her daughter would be abducted. Johnson was eventually chased and wrestled to the ground by two witnesses.
VIOLENT CRIMINAL HISTORY AND TRAUMA
The court reported that Johnson was a prolific offender with 30 convictions for 128 past offences. The investigation established that his record included a 2008 robbery where he stabbed a 65-year-old man in the neck, and a 2015 conviction for child abuse, specifically causing a child to watch a sexual act. The prosecution reported in 2020, that the seven-year-old victim has been left traumatised, following her mother everywhere and expressing a constant fear that “the man will come back,” identifying a priority assault by the judiciary to classify Johnson as a dangerous offender.
Judge-led proceedings at Liverpool Crown Court concluded with Johnson being jailed for six years with an extended three years on licence in 2020. For his actions in Liverpool and the nature of the series of robbery, sexual violence, and child abuse investigations reported over three decades, Duncan Johnson has been removed from the community. The investigation established that his forensic profile as a career criminal and child predator is now a matter of permanent record to ensure the public is protected from his “horrendous” violence.

MONITORING AND PUBLIC PROTECTION
In 2020, Johnson is managed as a maximum-risk predator under the statutory requirements of the Multi-Agency Public Protection Arrangements (MAPPA) in Merseyside. Due to the nature of the behaviour—specifically the series of persistence in attacking a mother and child in a public car park despite his extensive prison history—he is a priority for high-security incarceration. Authorities reported that the 2020 sentencing identifies Johnson as an individual who prioritised his own violent impulses and criminal greed over the principles of human decency and the life-safety of children.
As a dangerous offender and registered sex offender, his details are permanently logged on the national police database to ensure he is under the strictest supervision upon any future release. Authorities stated that the behaviour of Johnson identifies a commitment to clandestine child abuse and the systematic physical violation of the public. Any future attempt to assault the safety of a community or bypass his licence conditions results in immediate police intervention to ensure the ongoing protection of the public from a man who used a “shopper” mask to hide a predatory and persistent series of assaults.
QUESTION – Given that the offender “had 128 past offences” and was previously jailed for sexual offences against a girl, do you believe the law should legally mandate that “All Career Criminals with a History of Child Abuse” must receive “Mandatory Life Sentences” to prevent a series of assaults?
