What would you do if you discovered that a relative had been executed for murder?

When forensic mental health clinician Austyn Castelli received a text message about an executed family member, she expected to find a straightforward true crime story. Instead, she uncovered a tangled history and a death penalty case that raised more questions than answers.

Threat to Society follows one woman's attempt to understand the life, crime, and execution of Joseph Savino—and what that journey reveals about crime, punishment, and human behavior.

This is where the investigation begins.
