American Killers

Derek Joseph Daigneault murdered his 26-year-old cousin, Mandy Rose Reynolds, in Texas in April 2023 after staying at her San Marcos apartment while on felony probation with an active warrant. Daigneault shot Reynolds in the head, placed her body inside a large plastic storage container, transported it to Robinson and set it on fire. Her body was initially burned beyond recognition, but her dog Titan remained at the scene, and his microchip helped investigators identify Reynolds. Daigneault was arrested in Kansas after fleeing from police in Reynolds' stolen car and was convicted of murder in November 2024. He was sentenced to life imprisonment, and his conviction and sentence were affirmed by the Texas Tenth Court of Appeals in April 2026.

Dillon Alexander Waller is an American man convicted of the 2022 murder of his mother in New Mexico. The crime occurred within a domestic setting and involved attempts to conceal the offence. He was later convicted of first-degree murder and sentenced to life imprisonment.

Dr. Robert Bierenbaum became one of New York’s most infamous domestic killers after being convicted in the murder of his wife, Gail Katz, in a case widely known as “The Private Pilot Wife Disappearance.” A respected plastic surgeon and licensed private pilot, Bierenbaum was accused of killing Gail in 1985 before disposing of her body in a manner prosecutors argued exploited his aviation knowledge and access to aircraft. The case generated enormous public attention because Gail Katz vanished without a trace, leaving investigators with no body and little physical evidence for years. Prosecutors later argued Bierenbaum murdered his wife during escalating marital conflict before flying her body out over the Atlantic Ocean and disposing of it from a private aircraft. The combination of professional status, aviation-related body disposal allegations, and decades-long mystery made the case one of the most heavily discussed no-body homicide prosecutions in New York criminal history.

Edward Theodore Gein became one of the most infamous killers in American history after murdering two women and exhuming numerous bodies from local cemeteries near Plainfield, Wisconsin, during the 1950s. Although convicted of only two murders, the disturbing discoveries inside his farmhouse—including items fashioned from human remains—made Gein a cultural phenomenon whose crimes inspired characters such as Norman Bates, Leatherface, and Buffalo Bill. His case remains one of the most extensively studied in criminal psychology.

Edmund Emil Kemper III, known as the "Co-ed Killer," became one of America's most notorious serial killers after murdering ten people between 1964 and 1973, including his grandparents, six female college students, his mother's friend, and finally his own mother. His intelligence, willingness to discuss his crimes in detail, and extensive interviews with FBI profilers made him one of the most extensively studied serial killers in criminal psychology.

Edward "Jake" Wagner admitted participating in the Pike County massacre, one of the deadliest family murder cases in Ohio history, by pleading guilty to murdering eight members of the Rhoden family in April 2016. Prosecutors established that Wagner, together with his parents Angela Wagner and George "Billy" Wagner III and his brother George Wagner IV, planned and carried out the coordinated killings during a custody dispute involving his young daughter with Hanna Rhoden. In exchange for avoiding the death penalty, Wagner agreed to testify against his family members and became the prosecution's key witness during their trials. He is serving eight consecutive life sentences without the possibility of parole.

Elliot Rodger was an American mass murderer responsible for the 2014 Isla Vista killings in California. He carried out a planned multi-location attack targeting individuals in a university community. He killed six people and injured others before dying by suicide at the scene.

Erik Menendez became one of the most infamous figures in American true crime history after he and his older brother, Lyle Menendez, were convicted of murdering their wealthy parents inside their Beverly Hills mansion in 1989. The brutal killings shocked the United States and quickly transformed the Menendez brothers into household names during one of the most heavily televised murder trials of the 1990s. During the trial, Erik was portrayed by prosecutors as a privileged young man motivated by money and inheritance, while the defense argued he was a traumatised victim of years of emotional, physical and sexual abuse inside the family home. His emotional courtroom testimony and visible vulnerability became central to the public perception of the case, helping fuel decades of debate over whether the brothers were cold-blooded killers or abused sons driven by fear.
