Modus Operandi - Dismemberment

Robert Clive Napper became one of the United Kingdom's most infamous serial killers after murdering Rachel Nickell in 1992 and Samantha Bisset and her four-year-old daughter, Jazmine, in 1993. Before his identification, Napper committed numerous violent sexual assaults across South East London, becoming known as the "Green Chain Rapist." Advances in DNA profiling eventually linked him to the murders after years of investigative failures, making his case one of Britain's most significant forensic breakthroughs.

Adolfo de Jesús Constanzo became one of Mexico's most notorious serial killers after leading a violent criminal cult that combined ritualistic beliefs with narcotics trafficking during the 1980s. Operating primarily in Mexico City and Matamoros, Constanzo and his followers carried out numerous murders as part of ceremonies they believed would provide supernatural protection and success. The discovery of multiple victims at his ranch in 1989 exposed one of the most disturbing criminal conspiracies in Mexican history.

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.

Jack the Ripper is an unidentified serial killer responsible for a series of murders in the Whitechapel district of London in 1888. His crimes shocked Victorian society and became one of the most infamous unsolved cases in criminal history. Operating over a short but intense period, the killer targeted vulnerable women and carried out highly violent attacks before disappearing without identification. His ability to evade capture, combined with the brutality of the crimes and widespread media attention, has cemented his place as one of history’s most enduring criminal figures.
