Jace was a South African park ranger. He and his partner Ellie were both on patrol one day, investigating the mysterious dead carcasses of tourists to the park. They suspected that it was lions who had killed them. However, they then came across the real culprit, which was later figured out to be a Eustreptospondylus by the ARC team. The vicious Eustreptospondylus attacked, and killed, them both. (Fire and Water).
