S19, E17: While investigating the murder of television reporter Dawn Prescott (Guest Star Audra Blaser), detectives Lupo (Jeremy Sisto) and Bernard (Anthony Anderson) discover that she was involved in a love triangle involving another reporter at the station. This leads them to another suspect, veteran anchor Joe Delaney (Guest Star David Rasche), who was threatened by the success of his younger co-workers and may have hacked into their email to gain an advantage. As they search for the killer, the detectives uncover that Dawn was working on a major story surrounding a huge hedge fund fraud and there may be a connection with the recent murder of Fred Decker, a whistle-blower who filed an SEC suit against hedge fund owner, Fredric Matson (Guest Star Edward Hermann) and his wife Irene (Guest Star Jill Eikenberry). Also stars S. Epatha Merkerson, Sam Waterston, Linus Roache and Alana de la Garza.
