In the mid-1990s, Dominick Dunne was contacted by a Florida doctor who had read an article Dunne wrote about Dominique's death. The doctor told Dunne his daughter had recently become engaged to a chef named John Sweeney and wondered if it was the same John Sweeney responsible for Dominique Dunne's death. The man was later identified as the same John Sweeney. Dunne's brother Griffin later called the doctor's daughter and tried to convince her to call off her engagement. Sweeney accused the Dunnes of harassing him and later changed his name. In later interviews, Dominick Dunne said that for a time, he employed the services of private investigator Anthony Pellicano to follow and report on Sweeney's whereabouts and actions. According to Dunne's father, Pellicano reported that Sweeney had moved to the Pacific Northwest, had changed his name to John Maura and continued working as a chef. Dunne's father said that he later decided that he no longer wished to squander his life following Sweeney and therefore discontinued any attempts to keep tabs on him.
