In 1963, Jackson was killed in an industrial accident held at the quarry. Several workmen were injured in this incident. One of the main causes that led to management's strict rules was safety precautions which didn't go out well. His memorial was held at the entrance to the quarry in tribute to the workman. Bill and Ben were talking about Dennis Jackson after Edward departed back to Wellsworth and this went on from the afternoon until nighttime. Ben spoke to BoCo about what's going on and he says that Bill keeps telling him about the deceased workman. Bill and Ben talked about Dennis Jackson later on after the quarry had some severed mess-ups such as toolboxes going missing and some snapped couplings.
