What Happened to Polly in Riverdale? (Quick Scoop)

Polly’s Final Storyline in Season 5

Polly’s disappearance becomes a major mystery in Riverdale season 5, especially for Betty and Alice Cooper. She has been struggling for years – losing Jason, joining a cult, dealing with trauma, and doing survival sex work along the Lonely Highway to get by.

One night, Polly is chased on the Lonely Highway by a trucker, and later her blood (a rare type) is found at a smashed payphone, strongly hinting something terrible happened. Eventually, it’s revealed that she was kidnapped and murdered, with her remains left in the trunk of an old car in a junkyard.

Betty and Alice finally find Polly’s body in “Chapter Ninety-Three: Dance of Death,” which confirms she has been dead “pretty much this whole time.”

The Starkweather family, distant relatives tied to the trucker killings on the Lonely Highway, are held responsible for what happened, though it’s not fully clear which member actually killed her. Polly is later laid to rest, and Alice’s intense grief is explored in the musical episode “Next to Normal.”

Commentators point out her arc: secret pregnancy, cult involvement, exploitation, survival sex work, and then a brutal off‑screen murder that’s only confirmed late in season 5.
