Car Bomb Killer: The Strangest Murder-for-Hire Scheme in FBI History

A respected dentist. A city on edge. And a trail of bodies stretching across decades. This chilling FBI investigation peels back the mask of Glennon Engelman, the St. Louis “deadly dentist” tied to car bombs, staged accidents, and cold-blooded executions for cash. From a Madison County farmhouse massacre to a body staged at a seedy motel, investigators chase a phantom who always seems one step ahead. A car bomb shatters the quiet south side, but a misfired device from months earlier reveals an unexpected link. An ex-wife’s terrified testimony opens locked doors: an alleged quarry “accident,” a drag-strip blast, and a suspicious 1958 killing that never sat right. Insurance windfalls, forged signatures, a bogus confession, and a killer’s arrogance converge as agents connect dots others missed. How did a mediocre dentist outmaneuver cops for years? What tiny forensic match finally cracks the case? And why did so many people closest to him keep paying with their lives? Watch the full story to see how investigators exposed the method behind the murders and the motive that never changes. #TrueCrime #FBIFiles #GlennonEngelman #StLouis #ColdCase #Documentary
