Motivations - Domestic Conflict

Stephanie Hudnall became the focus of a high-profile Oklahoma homicide investigation following the death of her husband, William "Bill" Hudnall, in June 2011.

Following a lengthy investigation and trial, Stephanie Hudnall was convicted of first-degree murder and sentenced to life imprisonment.

Fotis Dulos became the focus of an internationally publicized criminal investigation after his estranged wife, Jennifer Dulos, disappeared from New Canaan, Connecticut, on May 24, 2019.

He pleaded not guilty to all charges but died by suicide in January 2020 before his trial began. Jennifer Dulos has never been found and is legally presumed dead.

Danny Johnson became one of Columbus, Ohio's most notorious domestic killers after murdering his girlfriend, 46-year-old Cathleen "Kit Kat" Howatt, at a homeless encampment near the Scioto River in April 2016. The killing followed a violent altercation witnessed by nearby residents who had become accustomed to Johnson's abuse of Howatt. Following a jury trial in 2017, Johnson was convicted of murder and sentenced to life imprisonment with the possibility of parole after 15 years.

David Tronnes became one of Florida's most notorious domestic killers after murdering his wife, Shanti Cooper-Tronnes, inside their Orlando home in 2018. Prosecutors alleged Tronnes killed Shanti after their marriage deteriorated amid financial disputes and his obsession with renovating their home for profit. He then attempted to disguise the homicide as an accidental fall during construction work. Following a lengthy investigation and trial, Tronnes was convicted of first-degree murder and sentenced to life imprisonment without parole.

The Tammi Pointer Killers refers to the group of six offenders responsible for the abduction, prolonged assault, murder, and burning of 18-year-old Alishah "Tammi" Pointer in Gary, Indiana, in October 1990. The offenders acted together throughout the crime, which culminated in Pointer being set on fire while still alive. The case remains one of Indiana's most notorious group murders because of its extreme violence, multiple perpetrators, and the lengthy prison sentences imposed following their convictions.

George Emil Banks became one of the most infamous mass killers in Pennsylvania history after murdering 13 people during a shooting spree in Wilkes-Barre on September 25, 1982. Among his victims were five of his own children, their mothers, and several relatives. The murders shocked the United States because of the extraordinary number of family members killed in a single attack. After decades of legal proceedings centred on his mental competency, Banks died in prison in 2024 without ever being executed.

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.

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.
