All her life, Astrid Holleeder knew that her older brother Willem was involved in crime; in their tough Amsterdam neighborhood, and as children of an abusive father, it wasn’t a shocking development. But she was stunned when, in 1983, Willem and his best friend, Cornelius van Hout, were revealed to be the masterminds behind the audacious kidnapping of the beer magnate Alfred Heineken. Although he served some time for the crime, it was only the beginning of the successful career of Holleeder. He became a celebrity criminal; he had a newspaper column, appeared on talk shows, and took selfies with admirers in Amsterdam. He got rich off of his investments in the sex trade and other businesses, but kept them well hidden. But when van Hout was assassinated and other of Holleeder’s associates started turning up dead, Astrid suspected that her brother had committed the murders. She decided to wear a wire and gather the evidence to put him away. If that didn't work, she told the New Yorker staff writer Patrick Radden Keefe, she would have to kill Willem herself. Willem is on trial now for multiple murders, and Astrid is testifying against him. Living in hiding, travelling in disguise, she tells Keefe the story of her complicity and its consequences. Keefe’s story about Astrid Holleeder, “Crime Family,” appeared in the magazine in 2018.
