While often referred to by the name of the Lifetime movie it inspired, *Husband, Father, Killer: The Alyssa Pladl Story*, the true events center around the Pladl family, specifically a father and his biological daughter who engaged in an incestuous relationship that ultimately led to a multi-state murder-suicide.

The Pladl Family: Key Figures and Tragic Biographies

The true story, which the media and the Lifetime film refer to using the name Alyssa Pladl, actually involves Katie Pladl as the primary victim of the incestuous relationship. Understanding the key individuals is essential to grasp the full scope of this tragedy.

• Katie Rose Fusco Pladl (Victim): Born in 1998, Katie was adopted as an infant. She was the biological daughter of Steven and Katie Pladl (the mother). At age 18, she sought out her birth parents, leading to the reunion that started the tragedy. She was the mother of Bennett Pladl. She was murdered at age 20.
• Steven Walter Pladl (Perpetrator): Born in 1974, Steven was Katie's biological father. He began an incestuous relationship with his daughter shortly after their reunion. He was charged with incest and adultery. He was the perpetrator of the murder-suicide, killing three people before taking his own life at age 43.
• Bennett Pladl (Victim): The infant son of Steven Pladl and Katie Pladl, born in 2017. He was killed by his father, Steven, during the murder-suicide at less than one year old.
• Anthony Fusco (Victim): Katie Pladl's adoptive father. He was also tragically murdered by Steven Pladl.
• Katie Pladl (Mother/Ex-Wife): Steven Pladl's ex-wife and Katie Rose Fusco Pladl's biological mother. She was the one who initially discovered the disturbing relationship between her husband and daughter, leading her to contact authorities.

The Disturbing Reunion and Incestuous Relationship

The beginning of the Pladl family tragedy can be traced back to 2016. Katie Rose, who had been adopted, reached out to her biological parents, Steven and Katie Pladl, on social media. The reunion was initially a source of joy, but the situation quickly turned dark. Steven Pladl, who was still married to Katie Pladl (the mother) at the time, developed an intense and inappropriate obsession with his biological daughter, Katie Rose. The obsession escalated into an incestuous relationship. Steven and Katie Rose moved in together in Knightdale, North Carolina, leaving Steven's wife and their two younger children. The estranged wife, Katie Pladl, discovered the disturbing relationship after finding journals and other evidence, which prompted her to contact the authorities. The couple was charged with incest and adultery in December 2017. The case garnered national attention not only for the incestuous nature of the relationship but also because Steven and Katie Rose had married in Colorado and had an infant son together, Bennett Pladl, born in 2017. The relationship was characterized by Steven's control and manipulation, with reports suggesting he was verbally and physically abusive toward Katie Rose.

The Tragic Timeline of the Murder-Suicide

The legal proceedings and the mounting pressure on the couple reached a breaking point in early 2018. Steven Pladl and Katie Rose had separated, and Katie Rose was living with her adoptive parents in Dover, New York. Steven was out on bond and was prohibited from having contact with his daughter. The final, devastating sequence of events unfolded on April 12, 2018.

The day began with a frantic 911 call from Katie Pladl (the mother) in North Carolina, reporting that Steven Pladl had taken their infant son, Bennett, and was threatening to kill himself and the baby. The chilling details that followed confirmed her worst fears:

• Murder of Anthony Fusco: Steven Pladl traveled to New Milford, Connecticut, where he murdered Anthony Fusco, Katie Rose Pladl's adoptive father.
• Murder of Katie Rose Pladl: Steven then drove to Dover, New York, where he murdered his daughter, Katie Rose Pladl.
• Discovery of Bennett Pladl: The body of their infant son, Bennett Pladl, was later found in a car in Knightdale, North Carolina.
• Steven Pladl's Suicide: Steven Pladl's body was found in a parked pickup truck in Dover, New York, having died from a self-inflicted gunshot wound.

In a single day, four lives were senselessly extinguished across three states: New York, Connecticut, and North Carolina. The case, which started with a shocking incestuous relationship, concluded with a horrific murder-suicide, leaving the surviving family members, including Katie Pladl (the mother) and her two younger children, to grapple with the unimaginable trauma.

The True Crime Legacy and Media Adaptation

The Pladl family tragedy has become a significant topic in the true crime genre, analyzed in podcasts, documentaries, and books for its extreme psychological and criminal elements. The sensational nature of the case—incest, a child born from the relationship, and a multi-state murder-suicide—ensured it would be revisited by media outlets. The most notable recent adaptation is the 2024 Lifetime movie, *Husband, Father, Killer: The Alyssa Pladl Story*. The film, which stars Jackie Cruz as "Alyssa" (the character based on Katie Rose Pladl) and Matthew MacCaull as "Steven," brought the disturbing events back into the public consciousness. Directed and executive produced by Elisabeth Röhm, the movie serves as a fictionalized account that attempts to explore the psychological manipulation and dark secrets that defined the relationship. The use of "Alyssa" in the film's title, rather than "Katie," is a common practice in dramatizations to protect the identity or provide a degree of separation from the real victims, though it often leads to public confusion over the actual names involved in the case. The enduring nature of the "Alyssa Pladl Story" in true crime circles is a testament to the sheer horror and complexity of the events, which continue to shock and intrigue audiences searching for answers about this devastating family collapse. The case highlights the critical need for mental health awareness and the devastating impact of unchecked obsession and control within a family structure.
