 The disappearance generated calls from psychics, extortionists and attention seekers.Several phone calls from people claiming to have the girls and offering to exchange them for ransom money were made to the Lyon family in the immediate aftermath of the sisters' disappearance.One began with an anonymous male voice on April 4, 1975, and demanded that John Lyon leave a briefcase with $10,000 inside an Annapolis, Maryland, courthouse restroom.
