Dominique Dunne – Tragic Poltergeist Star and Domestic Violence Victim

Dominique Dunne was a young actress on the rise when her life was cut short in 1982. Known for her role as Dana Freeling in the horror classic Poltergeist, she was strangled by her ex-boyfriend, John Thomas Sweeney, outside her West Hollywood home. The case drew intense media attention, partly because her father, Dominick Dunne, became a prominent crime journalist who wrote about the tragedy. Her story remains a powerful example of the devastating reality of domestic violence.

Born Dominique Ellen Dunne on November 23, 1959, in Santa Monica, California, she began acting in the early 1980s with television roles before landing her breakout feature film. Her relationship with Sweeney, a sous-chef at the celebrity-frequented Ma Maison restaurant, turned violent soon after they moved in together. On October 30, 1982, after an argument, Sweeney choked her until she lost consciousness. She was placed on life support and died four days later at age 22. The legal outcome — a voluntary manslaughter conviction and a sentence that saw Sweeney released after about two and a half years — sparked public outrage and a lifelong mission for her father to seek justice.

Who Killed Dominique Dunne? The Story of John Sweeney

John Sweeney Before the Murder

John Thomas Sweeney was a sous-chef at Ma Maison, a well-known Los Angeles restaurant frequented by celebrities. He met Dominique Dunne in 1981, and the two began a relationship that soon turned controlling and physically abusive. Friends and family later reported incidents of jealousy and prior violence, including an earlier choking episode for which Sweeney would later be charged with misdemeanor assault.

The Night of the Killing

On October 30, 1982, Sweeney went to Dunne’s West Hollywood home after she had ended the relationship. An argument escalated, and he strangled her. According to police reports, Sweeney admitted to the killing and also said he attempted to take his own life. Dunne was rushed to Cedars-Sinai Medical Center, where she was placed on life support. Her parents made the decision to remove her from life support on November 4, 1982, and her organs were donated.

Trial, Sentence, and Release

Sweeney received a sentence of roughly 6.5 to 7.5 years, but with time served and parole, he was released after serving about two and a half years. He later faced legal trouble again when he was arrested for domestic violence against another girlfriend in 1987. The light sentence remains a sore point for the Dunne family and advocates for domestic violence victims.

No, She Did Not Have Children

She had two brothers: Griffin Dunne, an actor and producer known for films like An American Werewolf in London, and Alexander Dunne. The family was devastated by the verdict.
