Their relationship moved fast but turned tragic soon after.

The Murder Case Against John Thomas Sweeney

John Thomas Sweeney strangled Dominique Dunne, leaving her in a coma. The jury found him guilty of voluntary manslaughter, not murder, sparking outrage.

Details of the Crime

Sweeney attacked Dominique Dunne at her West Hollywood home on October 30, 1982. She was rehearsing with actor David Packer when he arrived uninvited. They argued loudly outside the house.

Packer heard screaming and tried calling the police but didn’t get help right away. Sweeney grabbed Dominique by the neck and strangled her for about six minutes until she collapsed unconscious.

Dominique slipped into a coma after the attack and never woke up. Her family turned off life support six days later, on November 4, 1982. A month earlier, Sweeney had already choked her during another fight, leaving visible bruises on her neck.

Police arrested him shortly after this fatal assault outside her home in Santa Monica, California.

Trial and Sentencing

John Thomas Sweeney confessed to killing Dominique Dunne in 1982. He strangled her during an argument, leaving her in a coma. Five days later, she died at just 22 years old.

At trial, the court did not convict him of first-degree murder. Instead, they found him guilty of voluntary manslaughter on November 7, 1983. The judge sentenced him to six years but served only three years and seven months before his release in September 1986.

Where Is John Thomas Sweeney Now?

Sweeney left prison after serving only three and a half years for the killing of Dominique Dunne. He returned to work in Santa Monica as a head chef at The Chronicle restaurant. In 1994, news of his engagement reached Dominick Dunne, Dominique’s father.

Dominick informed the woman about Sweeney’s past, which ended their engagement.

Later, Sweeney accused Griffin Dunne, Dominique’s brother, of harassing him. Griffin had warned the woman against marrying Sweeney due to his violent history. After that incident, little is publicly known about his life or whereabouts today.

Her brutal death became a tragic symbol of relationship abuse in America. People rallied for stricter laws against abusers. Her family worked tirelessly to raise awareness about domestic violence.

Hollywood also took notice, with films and shows shedding light on similar tragedies like hers, keeping her story alive decades later.

Final Words

John Thomas Sweeney is alive, but his story remains chilling. His actions left deep scars on the families he hurt and forever marked history with tragedy. While he serves life in prison, Dominique Dunne’s memory lives on as a reminder of justice sought but not fully served.
