Dave Kroupa thought his relationship with Cari Farver was low-key, but Cari began sending threatening texts and emails. She even targeted Dave’s old girlfriend, Liz Goylar. The stalking persisted for years, and while the trauma drew Dave and Liz closer, authorities could never track down Cari for an arrest. But investigators tracing Cari’s digital footprint uncovered evidence that upended the case.

The Netflix documentary Lover Stalker Killer looks into this bizarre tale of obsession and violence. Among the women in Dave’s life, who could get away with years of online harassment? And who was willing to turn a romantic rivalry into murder?

In this episode of You Can't Make This Up, host Rebecca Lavoie interviews director Sam Hobkinson.
