To complete this achievement, you must find two pocket secretaries located in the Tower, prior to releasing Guerrero from Solitary Confinement:
- The first pocket secretary (containing the message "Schedule Change: Mejia, Oscar") is found in the Processing Area. In the Processing Area, there are two central rooms that have white walls, with a central aisle in between the two rooms. In the room that is on the east side of the central aisle, the relevant pocket secretary is found inside a drawer near a security terminal.
- The second pocket secretary (containing the message "Recovered Turret Command Logs") is inside an unlocked safe in the Automated Security office on level 5 of the Tower. This safe also contains a Praxis kit.
Obtaining the evidence contained in the two pocket secretaries will permit you to pressure Guerrero into confessing his murder of Wilburg when you release him from his cell in Solitary Confinement. During the conversation with Guerrero, select the "Wilburg's Murder" dialogue option to complete the achievement.
- The name of this achievement, as well as the icon, is a reference to the Ace Attorney series.
