The reasons for her sudden departure are unknown, but various hypotheses have been floated throughout the years. Some have offered that she became disenchanted with the LA scene, and returned to commercial artistry, while others maintain that she was modeling merely to gather the money for a breast reduction. It's hard to credit the latter theory, as one or two weeks of posing sessions would have covered those costs, and Roberta worked for over 4 years, producing a mountain of imagery. Since her retirement, claims of her being spotted in northern California in the mid 1980s have competed with other claims that she returned to Italy, and now lives there with her ******. It's difficult to choose between the two, and both might well be true. Roberta was, and will probably always remain, a will-o-the-wisp, going where life takes her. In addition to her dominant public name of Roberta Pedon, (which was often misspelled as Pedan), she was also commonly known as Melody O'Hare, in addition to a handful of "one-issue" names. Whether her name actually was Roberta Pedon or not, is also in some dispute, but it sounds believable to me, especially if for no other reason than it sounds so unlike what a Hollywood agent would've chosen.
