Erin Patterson became one of Australia’s most internationally discussed accused killers after allegedly poisoning multiple family members with deadly mushrooms during a lunch gathering in regional Victoria in 2023. The case generated extraordinary worldwide attention because of the unusual alleged murder method, the family dynamics involved and the mystery surrounding whether the poisonings were deliberate. The investigation rapidly became one of the biggest true crime stories in Australia, attracting nonstop media coverage, internet speculation and global fascination. The combination of toxicology evidence, alleged deception, suspicious behavior and courtroom developments transformed the case into one of the most discussed criminal prosecutions of the decade.

Harold Frederick Shipman became one of the most prolific serial killers in modern history after murdering patients under his care while working as a general practitioner in England. Convicted of 15 murders in 2000, a subsequent public inquiry concluded he had likely killed at least 215 patients, with some estimates suggesting the true total exceeded 250. Shipman's abuse of trust, combined with the enormous scale of his crimes, fundamentally changed patient safety, death certification, and medical oversight throughout the United Kingdom.

Alex Murdaugh became one of America’s most infamous disgraced legal figures after being convicted of murdering members of his own family in South Carolina in 2021. The case exploded into national headlines because Murdaugh came from one of the most powerful legal dynasties in the American South, with generations of influence over law enforcement, prosecutions and politics throughout the region. As investigators examined the murders, they uncovered a far larger web of corruption involving financial fraud, opioid addiction, theft, insurance schemes and abuse of legal power spanning many years. The collapse of the Murdaugh family empire transformed the case into one of the most heavily publicized American criminal scandals of the modern era.

James Toliver Craig, an Aurora, Colorado, dentist, murdered his wife of 23 years, Angela Craig, by poisoning her over a ten-day period in March 2023. Prosecutors established that Craig secretly obtained arsenic, cyanide and tetrahydrozoline while Angela repeatedly became seriously ill and required hospital treatment, ultimately administering a fatal dose of cyanide while she was hospitalised. Investigators uncovered internet searches about lethal and difficult-to-detect poisons, financial difficulties and extramarital affairs, while Craig later attempted to manufacture evidence supporting a suicide narrative and solicited the murder of the lead detective. A jury convicted him of first-degree murder and five solicitation charges in July 2025, and he was sentenced to life imprisonment without the possibility of parole.

Charles "Chase" Merritt murdered his business associate Joseph McStay, Joseph's wife Summer, and their young sons Gianni and Joseph Jr. after financial problems developed around the water-feature business Merritt worked on with Joseph. The McStay family disappeared from their Fallbrook, California, home in February 2010, beginning a mystery that lasted more than three years until their remains were discovered in shallow graves in the Mojave Desert near Victorville. Financial records, cellphone evidence and other circumstantial evidence eventually focused the investigation on Merritt, who was arrested in 2014. A jury convicted him of four counts of first-degree murder in June 2019, and he was formally sentenced to death in January 2020.

Daniel Krug is an American man convicted of the 2020 murder of his wife in Topeka, Kansas. The case became widely known due to the elaborate and sustained deception he created to conceal the crime, including fabricating a false stalker narrative to mislead investigators. He was later arrested, convicted, and sentenced to a lengthy term of imprisonment.

Chandler Michael Halderson murdered his parents, Bart and Krista Halderson, at their home in Windsor, Wisconsin, in July 2021 as his father began uncovering years of deception about his education, employment and future plans. Halderson killed and dismembered his parents, attempted to destroy and conceal their remains, and then reported them missing while claiming they had travelled to the family's cabin. Investigators dismantled his story through forensic evidence, digital records and location data that connected him to sites where remains were recovered. A jury convicted Halderson of both murders in January 2022, and he was sentenced to life imprisonment without the possibility of parole.

Andrew Phillip Cunanan carried out a five-victim murder spree across four states between April and July 1997 that culminated in the fatal shooting of Italian fashion designer Gianni Versace outside his Miami Beach home. Beginning with the murder of his former friend Jeffrey Trail in Minnesota, Cunanan killed architect David Madson, wealthy Chicago developer Lee Miglin and New Jersey cemetery caretaker William Reese before targeting Versace. The nationwide manhunt that followed became one of the largest in FBI history. Eight days after killing Versace, Cunanan died by suicide aboard a houseboat in Miami Beach as law enforcement closed in.
