Eddie Jacubois was a member of Troop D and was one of the few people who knew about the existence of the Buick Roadmaster. He was present at several of the lightquakes and he would later be involved in the killing of the thinking being. He brought in Brian Lippy with the help of George Morgan when this incident would happen. He helped Troop D kill the being that spawned from the Buick and would also be present at the death of Mister Dillon. He would also later help Troop D save Ned Wilcox and Sandy Dearborn from the Buick. Eddie would later buy Ned's car and commit suicide by crashing into the side of a bridge.
