Paradise isn’t your regular old murder mystery series. By the time the end credits roll on the premiere of Hulu’s gripping political thriller from This Is Us creator Dan Fogelman, a number of burning questions will be swirling around in your head.

Why the heck is the Paradise community living in a bunker?! Where is secret service agent Xavier Collins’ (Sterling K. Brown) wife?! How did President Cal Bradford (James Marsden) betray Xavier?! And crucially, who killed Cal?! And what was their motive?

Though Fogelman promises viewers willhave the answers they crave by the time Paradise‘s Season 1 finale concludes, after the three-episode premiere on January 28, our minds are considering all sorts of possibilities.

While we’ll ultimately have to wait to see how this compelling, twisty series unfolds, we’re here to break down the suspects in the president’s murder in hopes of figuring out who killed Cal. For context, critics have yet to see the finale of the eight-episode limited series, so rest assured, there will be no finale spoilers here until the finale airs. All we know is that Cal’s autopsy showed evidence of blunt-force trauma to the head — potentially from a large rock — that the first hit came on right side while standing, and that there were signs of struggle.

So who did it? Here’s what we know about the Paradise suspects three episodes in. We’ll be sure to update the list with new theories and revelations each Tuesday as the series continues.

Curious who killed Cal on Paradise? Three episodes deep, here are the people who may have taken the president’s life.
