Tristan Roberts became the subject of a major homicide investigation after murdering his mother, Angela Shellis, at Coed y Morfa nature reserve near Prestatyn, North Wales, in October 2025.

Vickrum Digwa became known in British criminal history after the murder of 18-year-old university student Henry Nowak in Southampton, England, on December 3, 2025. Prosecutors argued Digwa fatally stabbed the first-year University of Southampton student during a confrontation before attempting to portray himself as the victim when police arrived at the scene. The case attracted national attention because of the circumstances surrounding the stabbing and the controversy that followed. During the investigation and trial, prosecutors alleged Digwa falsely claimed Henry had attacked him and subjected him to racial abuse. The jury rejected those claims and convicted Digwa of murder. Public discussion later expanded beyond the killing itself to include the initial police response, which became the subject of significant scrutiny and debate across the United Kingdom.

Vince Marinello became known in true crime coverage after murdering his wife, sports anchor and television personality Trina Edwards Marinello, in a case that shocked Louisiana media circles. Prosecutors alleged Marinello strangled Trina inside their home in 2017 before attempting to stage and conceal aspects of the crime while creating what investigators later described as a disturbing “murder checklist.” The case generated widespread media attention because Trina Edwards Marinello was a well-known New Orleans sports journalist and former television anchor. Investigators later uncovered evidence suggesting Vince Marinello researched homicide methods, evidence concealment, and post-crime planning before the killing. The “murder checklist” allegations, combined with the couple’s deteriorating marriage and Marinello’s deceptive behavior after the homicide, turned the case into one of Louisiana’s most infamous domestic murder prosecutions.

Vincent Ambrosio is an American teenager who was convicted of murdering a young girl in Maryland in 2018. The case drew attention due to his age and the disturbing nature of the crime.

His conviction resulted in a lengthy prison sentence, reflecting the severity of the crime.

Waseem Daker became one of Georgia’s most controversial convicted killers after being found guilty in the 1995 murder of Delta flight attendant Karmen Smith and the attempted murder of her five-year-old son in Cobb County. Prosecutors argued that Daker carried out the attack as part of a long-running obsession with Smith’s roommate, Loretta Spencer Blatz, whom he had previously been convicted of stalking. The case drew national attention because of the violent nature of the crime, the lengthy delay before charges were filed, and the later disputes surrounding witness testimony and forensic evidence. The murder remained unsolved for years before investigators revisited DNA evidence collected from the scene. Hair evidence later linked to Daker became a central part of the prosecution’s case, eventually leading to his arrest and conviction more than a decade after the killing. The case later generated additional controversy after key witness Loretta Spencer Blatz partially recanted portions of her testimony following the trial, fueling debate around the conviction and keeping the case heavily discussed in true crime media, legal circles, and online communities.

Wayne Clifford Boden became one of Canada's most infamous serial killers after sexually assaulting and murdering four women in Montreal, Quebec, between 1969 and 1971.

He was sentenced to life imprisonment and remained incarcerated until his death in 2006.

Wayne Couzens became one of Britain’s most notorious killers after abducting, raping and murdering Sarah Everard in London in 2021 while serving as a Metropolitan Police officer.

The killing triggered national outrage, widespread protests and intense scrutiny of policing culture within the United Kingdom. Couzens’ crimes exposed serious failures surrounding misconduct warnings and vetting processes inside British law enforcement, while the murder of Sarah Everard became one of the most significant criminal and social justice cases in modern British history.
