According to investigators, it was the religious content of the transmission and the type of equipment used that drew them to CBN. The jamming signal left behind subtle technical clues that were captured on a VHS recording made at the Playboy Channel's uplink at the time of the event – like finding "fingerprints" in the video. After investigators were confident that they identified the brand of transmitter and character generator from the video, they concluded that CBN was the culprit. Haynie, of Virginia Beach, Virginia, was on duty at his job as an uplink engineer at the time of the jamming.
