Just four months after appearing in the 1982 blockbuster supernatural thriller, Poltergeist, 22-year-old actress Dominique Dunne was strangled by her ex-boyfriend, sous-chef John Thomas Sweeney, at her West Hollywood home. The attack put her in a coma for five days until she was declared brain dead and taken off life support.
Dunne was the daughter of heiress Ellen Griffin and Dominick Dunne, a film producer, writer, investigative journalist, and television host, and the niece of novelists Joan Didion and John Gregory Dunne. Her first break as an actress came when she was cast in the 1979 movie, Diary of a Teenage Hitchhiker. She soon appeared in the hit '80s television shows, Lou Grant, Hart to Hart, and Fame, before landing her first feature film role in the Steven Spielberg-produced supernatural thriller Poltergeist.
The trouble with her boyfriend Sweeney began shortly after the two moved in together, just weeks after meeting. A few months prior to her murder, two altercations occurred, one being his first attempt on her life by strangling. In 1983, Sweeney was acquitted of the second-degree murder charge, but was still found guilty of the lesser charge of voluntary manslaughter and also convicted of a misdemeanor assault for a previous attack. He was sentenced to 6 ½ years in prison, but only served three years and seven months.
