In this case as Dan is dead the property by default gets transferred to the heirs of the individual. Eve has no right to the property as because Dan did not had a will for the same and There is no written document that states that he is transferring the necklace to Eve. Again, Jeff is caught of collecting or picking up the necklace and anyways he cljas no claim of such property as well instead he can even be charged of possessing the necklace. As Dan died without a Will, the property will be transferred to his heirs.
Dan wants to give Eve a pearl necklace that Dan has in his safe deposit box...
