Prime Suspect

S1 E3: Kendra interviews Madelyn who gives her an important clue. As the team gets to work identifying this new lead, a friend of Captain Donovan appears at the TSIB offices. He tells them he saw Donovan the night before Flight 716 took off, and that he was agitated and unstable. With Donovan emerging as the prime suspect, Janet arranges a search warrant for the pilot’s homes. Meanwhile AJ is nursing his own obsession with the case, as he becomes fixated on an internet conspiracy that lays the blame for the crash on a shady Russian oligarch.
