When the crusading human-rights attorney Digna Ochoa was found dead of a gunshot wound in October 2001, her death was ruled a suicide even though she’d been repeatedly threatened, harassed, and kidnapped because of her work. Video maker Felipe Cazals tries to do right by her in his 2004 documentary, whose talking-head interviews are intercut with chilling dramatizations of the young woman being stalked, tortured, and killed. But instead of uniting these disparate elements with a narration that parses the facts, he dices Ochoa’s story into a series of inquiries, revisiting the same events from different angles and killing any momentum.
