This question might seem simple, but delving into his past reveals a complex and chilling narrative. Once notorious for the tragic murder of actress Dominique Dunne in 1982, Sweeney served a notably brief sentence before attempting to rebuild his life as a chef. However, the shadows of his violent past caught up with him, leading to an arrest in 2001 for a series of heinous crimes, including the attempted murder of Delia Balmer and the murders of Melissa Halstead and Paula Fields. Today, he remains incarcerated, serving multiple life sentences without parole.

John Thomas Sweeney’s life after the murder of Dominique Dunne reads like a troubling odyssey of avoidance, re-invention, and further violence. Upon his release in 1986, after serving less than four years of his six-and-a-half-year sentence, Sweeney stepped right back into the culinary world. He took up work as head chef at The Chronicle in Santa Monica, California, where he initially seemed to have successfully erased his dark past. The Dunne family, however, would not allow him to slip into obscurity. Their protests outside the restaurant prompted his resignation, and Sweeney later moved out of Los Angeles, disappearing into a quieter life under the new name John Maura. Still, it seems his demons followed him wherever he went.
What began as an act of manslaughter in 1982 evolved tragically into a far grimmer legacy. Years after Sweeney was released from prison, whispers of more violence emerged, culminating in his arrest in 2001. His relationship with Delia Balmer revealed chilling acts of control and brutality. Balmer, who survived an attempted murder at his hands in 1994, described a harrowing ordeal in which Sweeney terrorized her before attacking her with such ferocity that her survival was nothing short of a miracle.
But the story doesn’t stop there. Sweeney's heinous actions extended well beyond Balmer. In 2011, he was convicted for the murders of two former partners, Melissa Halstead and Paula Fields. Both women’s remains were discovered years apart—Halstead in Amsterdam in 1990 and Fields in London in 2001—each dismembered and discarded as though their lives were meaningless. Authorities suspect he may have claimed even more victims during a stretch of time between the 1970s and 1990, though some mysteries remain unsolved to this day.
Sweeney’s ability to avoid detection for years highlights both the grim persistence of his crimes and the failures of justice. For six years following his attack on Balmer, he evaded authorities while allegedly continuing to kill. His ability to re-enter society after murdering Dominique Dunne, hold down a job as a respected chef, and even change his identity underscores the alarming ease with which he was able to resume "normalcy" after acts of violence.
Sweeney’s sentencing in 2011 brought some sense of justice, though it came far too late for the women whose lives he shattered. By the time he was incarcerated at Belmarsh Prison in the UK, his string of victims—and the decades of lost time—painted an overwhelmingly grim picture. To this day, he remains a figure of both horror and tragic complacency, serving life without the possibility of parole.
