Allison Lassiter was the chief of security for the crime lord Ethan Stewart, situated on Dead Man's Rock. She possessed knowledge of the codes and layout of his compound, such information being retrieved telepathically by Jake Ramsey while he and Rosemary Dahl were making their escape from Stewart. Not long after their escape was made, the zerg invaded the planet, depopulating it. Lassiter was presumably among the list of casualties.
