In 1985, two 27-year-old friends left their suburban Detroit homes for a hunting trip in rural Michigan. When they did not return, their families and police suspected foul play. For 18 years, no one could prove a thing. Then, a relentless investigator got a witness to talk, and a horrifying story emerged. In 2003, this bizarre case hit the glare of the criminal justice system, as prosecutors charged two brothers, Raymond and Donald Duvall, with murder.

West Coast doctor Kenneth Stahl would do anything to free himself from his wife Carolyn. Then Adriana Vasco - Kenneth's former receptionist and mistress of nine years - obliged by introducing him to ex-con Dennis Earl Godley. The deal was set. Godley would murder Carolyn for thirty-thousand dollars. On the day after her 44th birthday, the trusting victim was lured to a lonely stretch of road. The deadly rendezvous took a shocking turn. Not only was Carolyn gunned down with a .357 Magnum, but Kenneth would also be killed.

In the fall of 1999, a 22-year-old woman was discovered naked and bleeding on the streets of a small New Mexico town south of Albuquerque. She was chained to a padlocked metal collar. The tale she told authorities - of being beaten, raped, and tortured with electric shock - was unthinkable. Until she led them to 59-year-old David Ray Parker, his 39-year-old fiancee Cindy Hendy, and the lakeside trailer they called their "toy box." What the FBI uncovered was unprecedented in the annals of serial crime. 

Greg DeVillers was a top biotech executive, and Kristin Rossum was embarking on a career in toxicology at the San Diego Medical Examiner's office. They seemed to be happily married, living the American dream. But only months shy of their second anniversary, Kristin found her handsome husband dead from a drug overdose - his corpse sprinkled with rose petals. By his side was their wedding photo. Authorities deemed it a suicide. Until they discovered that the rare poison found in Greg's body was the same poison missing from Kristin's office. 

All Diane Bertalan really knew of her new husband, John, was that he was a widower, he lavished her with gifts, and he preferred to keep his past a secret. What she didn't know was that the FBI had been watching him for years. In the fall of 2000, she found out why - it was a crime that had been haunting authorities for decades. They called it the mystery of the Lady in the Box.

Praying for a happy ending, friends and family stood by Laci's grieving husband Scott. Four months later, Laci's decomposed body was found in the murky waters of San Francisco Bay.

It was a sad closure to an exhaustive search, and a grim end to a marriage that by all accounts had appeared to be perfect.

Hedley Thomas takes you behind the scenes with a blow-by-blow account of one of the most intriguing and enduring murder mysteries of our time - the crime, the podcast investigation, the sexual exploitation of teenage students, the courtroom drama - and how justice was finally delivered.

On September 28, 2000, former Indiana state trooper David Camm made a frantic call to his former colleagues in the state troopers office: He had just walked into his garage and found lying on the floor the bodies of his 35-year-old wife Kim and their two children Brad and Jill, ages seven and five.

For twenty years, Ken and Kristine Fitzhugh and their two sons had lived lives of comfortable middle-class normality. Then came the shocking news that Kristine Fitzhugh was dead, the victim of a terrible accident.... By the time the Palo Alto Police Department looked closer at the death of Kristine Fitzhugh, there could be only one conclusion. Someone had murdered Kristine in her own home, inflicting a series of horrific blows to the back of her head, and then cleaned up the mess to make it look like an accident.

When the bodies of three teenagers were found on the shores of Lake Waco, Texas, in July 1982, even seasoned lawmen were taken aback by the savage mutilation and degradation to which they had been subjected. Yet only 52 days after the gruesome triple-murder was discovered, frustrated authorities suspended the case indefinitely. Patrol Sergeant Truman Simons, who had been called to the scene that night, saw the carnage firsthand - and vowed to find the ferocious killer or killers. He soon became a man with a mission, risking his career and his family's safety in search of evidence. 

He'd been shot in the head, decapitated, and set on fire. Who could have turned on the real-estate ace with such bloodthirsty fury? Even before the remains were found, circumstantial evidence was building against Rudin's 52-year-old wife, Margaret, who stood to inherit a handsome share of her husband's fortune. Rudin's friends also suspected Margaret, and the victim had thought that his wife was trying to poison him when he was alive. Then a chilling caveat was discovered in Rudin's living trust: should he die under violent circumstances, an investigation should be conducted.

Mike DeBardeleben was known as the Mall Passer for the way he passed off fake money at local shopping centers. But when US Secret Service agents finally arrested him, they were met with more than just phony bills. They found that their counterfeiter led a shocking double life.... DeBardeleben's home was littered with drugs, bondage gear, and a collection of audio tapes in which he recorded the abuse of his countless victims. 

By all accounts, Thomas Gilbert Jr. led a charmed life. The son of a wealthy hedge fund manager and a financier, he grew up surrounded by a loving family and all the luxury an Upper East Side childhood could provide: education at the elite Buckley School and Deerfield Academy, summers in a sprawling seaside mansion in the Hamptons. He was strikingly handsome, moving with ease through glittering social circles and following in his father's footsteps to Princeton. But Tommy always felt different, and the cracks in his façade began to show. 

Ten-year-old Krystal Surles watched as her best friend was murdered before the intruder slashed her throat with a 12-inch boning knife.

He slipped like a sinister shadow in the night, stalking, then savagely attacking. Most of his unsuspecting targets were shot at close range, and one woman was stabbed over one hundred times. The taunting, bizarre letters alleged killer Heriberto Seda sent to the police and the New York Post were full of strange symbols and mysterious references to the Zodiac. For six terror-filled years, the Zodiac killer ruled the night, claiming nine victims in his homicidal rage. One of the biggest manhunts in New York City's history was unleashed.
