This documentary is based almost entirely on the 2020 ruling of the Supreme Court of California, which affirmed Michael Joseph Schultz's conviction and death sentence. What comes from a single witness is attributed to that witness.
Episodes of violence described at the penalty phase were never charged as crimes; they are presented as testimony only.
Cynthia Burger's answering-machine message is quoted from the court ruling and shown as text. No synthetic voice imitates her or anyone else in the case.
Narration uses a synthetic voice. Illustrations and 3D recreations are labeled on screen and do not show real people or the real home.
