Status: missing, presumed deceased; presumably committed suicide when he left Jericho in ep 1.3, Four Horsemen Background: Seems to have been an employee of the salt mine company. What we know: Shep was with a group of Jericho residents who waited out the fallout in the salt mine. He was apparently involved in the death of another resident, Scott, who panicked while in the mine. When he left in Four Horsemen he gave Heather a note that blamed himself for the death of Scott which indicates that he probably never planned to return to Jericho. He also apologized for leaving his family (he had at least one young daughter who he is seen holding at the end of the Pilot episode).
