The next day, police received a phone call from a woman claiming to be Reso's kidnapper, directing them to a letter in a highway street sign. In it, the kidnappers claimed to be members of the Greenpeace Environmentalist group who were furious at Exxon after the Exxon Valdez oil spill three years earlier, as well as the 1985 deliberate Sinking of the Rainbow Warrior that killed Greenpeace photographer Fernando Pereira. The note demanded $18.5 million in used $100 bills for Reso's release. The money was to be put into several Eddie Bauer laundry bags and dropped outside a restaurant on River Road. Although the FBI had the money ready and waited outside the restaurant for over an hour, the kidnappers never showed up.
