For years, Israel Keyes lived what appeared to be an ordinary life working construction, traveling across the United States, and avoiding suspicion.

Behind that façade was a calculated and methodical killer.

Keyes operated differently from most known serial offenders. He planned crimes years in advance, buried “kill kits” across the country, and chose victims at random making patterns nearly impossible to detect.

His arrest in 2012 exposed a disturbing level of premeditation and raised chilling questions: how many victims were there, and how many cases may never be linked to him?

In this episode, we examine Keyes’ methods, the investigation that led to his capture, and why his case continues to unsettle investigators and the public alike.
