Events of Criminal Case
Agent Riordan came to Chief Ripley and demanded that the Bureau give the right to investigate Jonathan Stafford's murder to the FBI. However, Ripley said that the Bureau is allowed 24 hours to investigate, and only 12 hours have passed. Agent Riordan said that he would be waiting for the 24-hour mark to pass.
Agent Riordan first came along with his partner to arrest Marina Romanova, suspecting her of conspiring with her mother, Natasha Romanova, in the kidnapping of President James Hewett. They said that they had orders (which turned out to have come from Vice President Sarah Bennett) to do so and threatened Jonah with arrest as well after he tried to break Marina out.
Later, while Jack and the player were talking to Sarah, he approached her and told her that the van used to take the President away from Air Force One was tracked to the New York cloisters. Overhearing this debriefing, Jack and the player left to the cloisters.
Even later, while Sarah was being arrested after the evidence pointed to her, Riordan and his partner protected the vice president after she told them to take Jack and the player away. The two forced the Bureau cops to either stand down or get arrested. The cops then left the vice president's office after she had escaped.
