Foley's Islamic State captors had demanded $132.5 million from his parents and political concessions from Washington. Authorities say neither obliged. The militants revealed Foley's death in a video released Tuesday.
Speaking on NBC's "Today" John and Diane Foley from Rochester, New Hampshire, said they had last heard from the captors via several emails in December. They say they set up a special email address and sent multiple messages to try to engage them.
John Foley said he was excited to see the latest email, even though it threatened execution. He says he had hoped they would be able to negotiate with the captors.
