Dr. Jonathan Nyce, an asthma sufferer, had achieved medical breakthroughs that made him rich - and offered hope to countless people. Michelle's beauty made her an object of desire. And adultery was her husband's worst nightmare.

At first, the residents of Kauai Beach Resort took little notice of their new neighbors. The glamorous blonde and her tall husband fit the image of the ritzy gated community. The couple seemed to keep to themselves - until the police knocked on their door with a search warrant.

Inside a beautiful house in Philadelphia's ritzy Main Line section lay the body of a young mother - dead of an apparent drowning in her bathtub. With no sign of a break-in, no history of marital problems, and the naïve belief that these things sometimes just happen, Stefanie Rabinowitz's family prepared to bury the 29-year-old wife and mother. But at the 11th hour, because Stefanie was so young, and because there were no witnesses to her death, an autopsy was ordered. And what it revealed was unthinkable: Stefanie had been murdered.

Lacey Spears made international headlines in January 2015, when she was charged with the "depraved mind" murder of her five-year-old son, Garnett.

To the outside world, Lacey had seemed like the perfect mother, regularly posting dramatic updates on her son's harrowing medical problems. But in reality, Lacey was a textbook case of Munchausen Syndrome by Proxy.

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. 

Nothing could have shocked the sleepy community of Morgantown, West Virginia, more than the lurid details that surfaced after a house fire claimed the life of Shelly Michael's husband, Jimmy.

Did Shelly Michael, a respected nurse and mother, kill her second husband and torch her own home?

John Edward Robinson was a 56-year-old grandfather from rural Kansas. An entrepreneur and Eagle Scout, he was even honored as "Man of the Year" at a Kansas City charity.

On March 16, 1992, Elizabeth DeCaro, a 28 year-old mother of four, was found dead in her own home, murdered execution-style with two bullets to the head. Her husband, Rick, was immediately a suspect, having previously struck her "accidentally" with the family van after taking out a $100,000 life insurance policy on her. A Killer Among Us presents the true shocking story of Elizabeth's family and their search for justice against the man who continued to play father to the children whose mother he had killed.

On a November morning in 2015, Christopher Jackson waited for his fiancée, Angila Wilder, to pick him up from work as she always did. But this time, she didn’t show - and Christopher’s calls went unanswered. The police found what looked like a scene from a horror movie at their home. The backdoor kicked in. A bedroom splattered with blood. And a pregnant young woman violently stabbed to death.

A promising young attorney and a dedicated family man, Michael Fletcher seemed to have it all. But in the summer of 2000, Michael found himself standing trial for the murder of his pregnant wife, Leann.

The day before Halloween 2004 was the last day on Earth for respected, well-liked college professor Fred Jablin. That morning, a neighbor discovered his body lying in a pool of blood in the driveway of Jablin's Virginia home. Police immediately turned their attentions to the victim's ex-wife, Piper, a petite, pretty Texas lawyer who had lost a bitter custody battle and would do anything to get her kids back. But Piper was in Houston, 1,000 miles away, at the time of the slaying and couldn't possibly have been the killer...could she?

By all accounts, Stager seemed to lead the perfect life in her community in Durham, North Carolina. After her husband, popular high school coach Russ, died tragically, the police were inclined to believe her story - that she accidentally shot him. Suspicions rose when the police discovered that Stager's previous husband had died similarly 10 years prior.

They were a picture-perfect family - until a bitter divorce drove Darren Mack over the edge. A Reno millionaire, Mack was ordered by the court to pay his wife $10,000 a month in alimony. Instead, he stabbed her in the garage while their daughter watched TV upstairs. The only person Mack hated more than his wife was the family court judge who presided over their divorce. So, after killing his wife, he loaded his gun and went after the judge...and headed for Mexico with a stash of concealed weapons.
