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.

Dzhokhar Tsarnaev is one of the perpetrators of the 2013 Boston Marathon bombing, carried out alongside his brother Tamerlan Tsarnaev. The attack resulted in multiple deaths and widespread injuries, making it one of the most significant acts of terrorism in the United States in recent history. Tsarnaev was captured following a large-scale manhunt and later convicted on multiple charges. He was sentenced to death, and his case continues to be the subject of legal appeals and public debate.

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.

Eric Edgar Cooke was an Australian serial killer responsible for a series of murders in Perth during the late 1950s and early 1960s. His crimes were notable for their randomness and variety, which initially made the investigation difficult. Cooke was eventually captured and confessed to multiple killings. He was convicted and executed in 1964, becoming the last person to be hanged in Western Australia.

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.
