Day 1
Doctor George Ferragamo was Kieth Palmers therapist prior to day 1 but when he threatened to go forward with evidence implicating Keith Palmer in day 1 Carl Webb had him killed through arson. David Palmer was confident that the fire was arson and that Carl was involved.Carl later met with Palmer, he told him that evidence was placed at the crime scene that would implicate Keith in Ferragamo's murder. The evidence would be discovered by the fire marshal if they were pointed in the right direction. Keith soon met with Carl and accused him of being complicit in the death of Ferragamo. Carl told Keith that he was "over his head" and that the he would be implicated in Ferragamo's death if he didn't back off. Carl was unaware that Keith was wearing a wire and that the whole conversation was recorded. Keith handed over this recording to his father and David Palmer later revealed the truth to the media.
