Any true crime junkie is going to be all over The Keepers, a seven-part Netflix series about the unsolved murder of a Baltimore nun in 1969. If they're legitimate fans, they'll revel in the appearance of forensic pathologist, Werner Spitz. Midway through the sixth episode, Spitz's assistant rattles off the cases he's worked on: the assassinations of John F. Kennedy and Martin Luther King Jr., the murder of JonBenet Ramsey, plus the trials of O.J. Simpson, Richard Ramirez, Phil Spector, Casey Anthony, Michael Petersen, the West Memphis Three, and the Norfolk Four. This who's who of true crime documentary subjects appear in a montage lumping them together as a kind of monument of murder mystery. If Spitz is involved, you know the story is significant.
