Son of Sam: The Story of America's Most Dangerous Serial Killer

David Berkowitz is rightly considered one of the most dangerous serial killers living today. In 1976, the 23-year-old turned shootings into a hobby. Every month David Berkowitz went for a walk in a park to find a couple of teenagers secluded in some car—and shoot them. For a long time, his crimes simply weren’t being noticed. And then David had to write several letters—whose contents literally paralyzed New York. The messages were sent in the name of a certain Son of Sam. The sender was identified only after a year and a half.
Who is David Berkowitz? What made him kill, and who is this mysterious Sam? Was Berkowitz insane, or do we need to acknowledge that killing for fun can also be done by ordinary people? How did a serial killer become a preacher with a multi-thousand-strong army of fans—and what made him cooperate with the FBI? Read the true-crime investigation by criminal psychologist Mickey Knox, based on letters, interviews, and conversations with psychiatrists.
