Joyce Aparo seemed to be the perfect single mother. She doted on her sixteen-year-old daughter, Karin, encouraging her musical ability and lavishing affection on her.

When Karin met the troubled yet brilliant Dennis Coleman, the two fell head-over-heels. But Joyce disapproved—so she had to die.

Verteran investigative journalist Stevie Cameron first began following the story of missing women in 1998, when the odd newspaper piece appeared chronicling the disappearances of drug-addicted sex trade workers from Vancouver's notorious Downtown Eastside. It was not until February 2002 that pig farmer Robert William Pickton would be arrested, and 2008 before he was found guilty, on six counts of second-degree murder. These counts were appealed and in 2010, the Supreme Court of Canada rendered its conclusion.

On February 13, 2017, two Indiana teenagers, Abigail Williams, 13, and Liberty German, 14, went for a walk in the woods near the abandoned Monon High Bridge. They never returned home.

For years, Eddie Lee Sexton ruled his large family like Charles Manson. The depraved patriarch dominated his ragged brood of twelve children mentally, physically, and sexually, and enforced every cruelty imaginable, from vicious beatings to raping his daughters and fathering their children. Finally, in 1992, Sexton's eighteen-year-old daughter Machelle, seeking refuge in a women's shelter, revealed the shocking, sordid details of her father's abuse to authorities. As the law attempted to catch up to Eddie Lee Sexton, he moved his family to a mobile home in western Florida.

Ann Rule was working on the biggest story of her career, tracking the trail of victims left by a brutal serial killer. Little did this future best-selling author know that the savage slayer she was hunting was the young man she counted among her closest friends. Everyone's picture of a natural winner, Ted Bundy was a bright, charming, and handsome man with a promising future as an attorney. But on January 24, 1989 Bundy was executed for the murders of three young women - and had confessed to taking the lives of at least thirty-five more women from coast to coast.

On May 31, 2014, in the Milwaukee suburb of Waukesha, Wisconsin, two 12-year-old girls attempted to stab their classmate to death. Morgan Geyser and Anissa Weier’s violence was extreme, but what seemed even more frightening was that they committed their crime under the influence of a figure born by the internet: the so-called “Slenderman”. Yet the even more urgent aspect of the story, that the children involved suffered from undiagnosed mental illnesses, often went overlooked in coverage of the case.

After his December 2003 arrest, registered nurse Charlie Cullen was quickly dubbed "The Angel of Death" by the media. But Cullen was no mercy killer, nor was he a simple monster. He was a favorite son, husband, beloved father, best friend, and celebrated caregiver. Implicated in the deaths of as many as 300 patients, he was also perhaps the most prolific serial killer in American history.

This is the full true story of what happened.

Bryan Stevenson was a young lawyer when he founded the Equal Justice Initiative, a legal practice dedicated to defending those most desperate and in need: the poor, the wrongly condemned, and women and children trapped in the farthest reaches of our criminal justice system. One of his first cases was that of Walter McMillian, a young man who was sentenced to die for a notorious murder he insisted he didn’t commit. The case drew Bryan into a tangle of conspiracy, political machination, and legal brinksmanship—and transformed his understanding of mercy and justice forever.

Two days after Christmas, 2011, Russel Faria returned to his Troy, Missouri, home to find his wife, Betsy, dead, a knife still lodged in her neck.
