On May 10, 2009, attorney Rodrigo Rosenberg Marzano was cycling through Guatemala City when he was killed by a gunman on a grassy knoll. His murder touched off one of the biggest and wildest scandals in Guatemalan history, with people as high up as President Alvaro Colom implicated in the crime. Journalist David Grann told this story in his 2011 New Yorker piece “A Murder Foretold,” one of the best true-crime accounts I’ve ever read and a virtual master class in story structure. Documentary maker Justin Webster commendably tries to duplicate Grann’s narrative here, but his reenactments, featuring actors and some interview subjects, diminish the story’s power, making an otherwise strong documentary seem like an episode of America’s Most Wanted.
