10 cases reported in full
The 1998 killing of University of Wyoming student Matthew Shepard near Laramie became a national catalyst for hate-crime law, culminating in the 2009 federal Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act.
The 1964 murder of Catherine 'Kitty' Genovese in Queens and the disputed '38 witnesses' narrative that gave rise to bystander-effect research, examined against the later corrections by The New York Times and scholars.
How the 1994 murder of seven-year-old Megan Kanka in Hamilton Township, New Jersey, by a twice-convicted neighbor led to Megan's Law and nationwide sex-offender community notification.
Twelve-year-old Polly Klaas was abducted at knifepoint from a Petaluma slumber party in 1993. Her case helped pass California's Three Strikes law and reshaped how the nation searches for missing children.
How the 1983 murder of Lynda Mann and the 1986 murder of Dawn Ashworth in Leicestershire became the first case ever solved by DNA fingerprinting, clearing an innocent man and convicting Colin Pitchfork.
In December 2002, Laci Peterson, eight months pregnant, vanished from Modesto, California. The recovery of Laci and her unborn son, Conner, and the conviction of her husband helped shape the federal Unborn Victims of Violence Act, known as Laci and Conner's Law.
Brandon Swanson, a 19-year-old Minnesota college student, vanished on May 14, 2008, after his car went off a rural road and his late-night phone call to his parents cut off mid-sentence. He was never found, and his case led Minnesota to enact Brandon's Law.
In 1982, seven people in the Chicago area died after taking Extra-Strength Tylenol capsules laced with cyanide. The killer was never identified, but the case rewrote how every sealed product is sold.
Six-year-old Adam Walsh was abducted in 1981 from a Florida department store. His parents turned grief into a national missing-children movement and a federal law that still bears his name.
In 1932 the 20-month-old son of aviator Charles Lindbergh was taken from his crib near Hopewell, New Jersey. The case ended in a conviction still debated today and created federal kidnapping law.
