The documentary includes interviews with Randolph, witnesses and victims’ family members.
“Normally, the more you investigate, the closer you get to an answer,” Slepian told TIME. “This investigation did the exact opposite. Every answer widened the frame. Another marriage, another state, another death, another witness. And that’s when I realized that what we were covering wasn’t just a single murder case, but a pattern that had been unfolding over decades.”
The 1.5-hour documentary unfolds in real time, unraveling the disturbing case and excavating Randolph’s past. At the end of the trailer, he exclaims, “In the end…I’m gonna win!” Talk about something that’ll keep you up at night.
