Presumed Innocent may be a new legal thriller on Apple TV+, but the story of chief deputy prosecutor Rusty Sabich being investigated for the murder of his colleague and mistress Carolyn Polhemus is decades old.

The limited series starring and executive produced by Jake Gyllenhaal is the latest adaptation of Scott Turow’s bestselling 1987 novel of the same name. In 1990, the text inspired a film starring Harrison Ford, Brian Dennehy, Bonnie Bedelia, and Greta Scacchi. And though fans of the book or movie may think they have the ending of the Apple TV+ series all figured out, with some major changes already introduced in the first three episodes, it’s clear that creator that David E. Kelley and executive producer J.J. Abrams aren’t afraid to switch things up. So who’s to say the ending or the killer can’t change?

Critics have yet to see the finale of the eight-episode limited series, so even I don’t know who’s responsible for Carolyn Polhemus’ (Renate Reinsve) death. What I do know is that Carolyn likely knew her killer based on the team’s findings. So we’re here to assemble the suspects of the Apple TV+ series three episodes in and will update the list as the series progresses.

Curious who killed Carolyn Polhemus on Presumed Innocent the Apple TV+ series? Let’s meet the suspects so far. (FYI: If you haven’t seen Presumed Innocent the movie, spoilers do lie ahead at the very end. Be warned, but don’t be mad at us, because — again! — it came out in 1990!)
