A small plane carrying four Italian tourists, including Vittorio Misson, the head of the Missoni fashion business, disappeared off the coast of Venezuela on Friday.
A sea and air search began Saturday and is still underway.
As the search for the aircraft carrying Vittorio Missoni, his wife Maurizia Castiglioni and two others continues, family members are "exploring other possibilities."
Angela Missoni, Vittorio Missoni’s sister and the chief designer of the Missoni label, issued a statement saying that the family had not given up hope.
