Paramount+ aims to (posthumously) unmask the Monster of Green Hollow, a rumored serial killer believed by many to have murdered dozens of people decades ago.

In new documentary series My Killer Father: The Green Hollow Murders, Lucy Studey, one of Donald Studeys daughters, claims she knows where the bodies are buried. Like, literally theyre in that stone water well right over there, she says. Lucy says she was there when Don dumped bodies and covered them in lye to expedite the decomposition.

Another of Dons daughters says he was a good guy and this is all a big, fat lie (the kind that doesnt eat away human flesh and bone). Don is dead now himself as of 2013, actually and the only bones recovered from his alleged mass-burial site thus far have been from animals. So who is the crazy one? No, seriously, were asking because the answer remains a mystery. Perhaps not for long. The Hollywood Reporter can exclusively reveal the trailer (below) for My Killer Father: The Green Hollow Murders, a three-part series that premieres in full on Paramount+ on Tuesday, April 28.

At best, Don Studey was suspiciously surrounded by death. Three of his five wives apparently killed themselves, officially, a 60 percent suicide rate. In the 1970s, when the murders allegedly began, the suicide rate in Iowa was like 12 in every 100,000 people, or about 0.00012 percent. So, statistically, being married to Don was, at best, a severe mental-crisis hazard.

The trailer opens and closes with what appears to a human-shaped stuffed tarp being dragged off the property where the bodies are supposedly buried. So thats not a great sign for Dons innocence.

Nor are these quotes:

He loves you or he hates you, one of filmmaker Aengus James interview subjects says in the trailer. And if he hates you, youre dead.

Theres no question in my mind that Don was a killer, says another. Hes the personification of evil.
