Carlos Ghigliotti was a thermal imaging analyst hired by the House Government Reform Committee to review tape of the siege at Waco, Texas. After reviewing the tape, he determined that the FBI had fired shots on April 19, 1993, contradicting the FBI explanation that the light bursts on infrared footage were reflections of sun rays on shards of glass or other debris that littered the scene.
At the age of 42, Carlos Ghigliotti was found dead on April 28, 2000. There was no sign of a break-in or struggle at the firm of Infrared Technology where the badly decomposed body of Ghigliotti was found. Ghigliotti had not been seen for several weeks.
