Had someone in the department been running Jiro’s icon when Sam encountered it in the Matrix last week? The data department would have known about Jiros injuries, and they would have had physical access to Jiro’s cyberdeck. A brain-fried decker would be impossible to hide, but a good back-up team might have been able to jack out the icon’s controller before the black ice got him. Using someone else’s deck was punishable by expulsion from the corporation as well as hefty fines, but that wasn’t always enough to deter a dedicated hacker. But whoever had been running Jiro’s icon had tampered with the Wall, which meant even harsher sanctions. If it were one of Addison’s group behind Jiro’s icon, they would all be subject to dismissal if their actions were discovered. They had more than enough reasons for a coverup.
