Dominique Dunne had dated –

  1. John Thomas Sweeney – She met John Thomas Sweeney in 1981 at a party. He worked as a sous-chef at the restaurant Ma Maison and only after going out for a few weeks, the couple moved into a one-bedroom house on Rangely Avenue in West Hollywood together. However, the relationship soon started falling apart due to Sweeney’s possessiveness and jealousy and the couple fought frequently and Sweeney began physically abusing Dunne. It was reported that during an argument between the duo on August 27, 1982, clumps of her hair were ripped from the roots by Sweeney. Following this, Dunne fled to her mother’s house but Sweeney later showed up and began to bang on the door and windows, demanding to be let in. Although Dunne’s mother told him to leave and threatened to call the police, Dunne decided to return to their home and continued their relationship after a few days.
    On September 26, 1982, he grabbed her by the throat, threw her on the floor, and began to strangle her during an argument at their home. After a friend who was staying with the couple heard “loud gagging sounds” and ran into the room where Dunne was being attacked, Dunne accused Sweeney of trying to kill her but he denied the allegations and asked her to come back to bed. Several events followed and they broke up soon after and it was Sweeney who later strangled her to death.
