He was portrayed by Kyle Gatehouse.
Conrad Cern was under government surveillance for his radical hate blog against the president, James Sawyer. Disguised as a Janitor, Cern placed a bomb into a bin trolley, blowing up the Capital Rotunda, which destroyed it. Despite the fact that Captain Hutton brings him up on his intelligence report and Capitol Police officer Kellerman recognized the picture of when he saw him as a janitor before the Capitol bombing, Cern is not seen being captured or killed.
