Snapped

Who are these women and what drives them to kill? Oxygen's hit true crime series, Snapped, profiles fascinating cases of women accused of murder. Did they really do it? And if they did, why? Whether the motivation is revenge against a cheating husband, the promise of a hefty insurance payoff, or putting an end to years of abuse, the reasons are as varied as the women themselves. From socialites to secretaries, female killers share one thing in common: at some point, they all snapped. Each episode of Snapped chronicles the life of a woman who has been charged with murder. These shocking but true stories turn common assumptions about crime and criminals upside down, and prove that even the most unlikely suspects can be capable of murder.

Buried in the Backyard

Buried in the Backyard examines true-crime stories of victims found buried in the most unsuspecting of places. While most people enjoy their backyard as a safe haven, others are not so lucky when they discover the horrors lurking beneath well-trimmed hedges and manicured fences. Uncovering the remains is only the beginning, however, as each hour-long episode follows a unique police investigation to identify the body, determine a cause of death and find the person responsible. Captivating recreations, along with first-hand accounts from those closest to the victims and law enforcement agents involved in the case, bring each shocking tale to life. As investigators dig into the "how" and "why" surrounding each crime, viewers are taken on an unpredictable journey and reminded that this could happen to anyone - in any home, in any neighborhood.

The Twelve

Twelve citizens are called for jury duty on a high-profile murder trial as traumatizing as it is controversial, in which a woman stands accused of killing her sister's child.

As time goes by, the murder trial becomes a trial, not only for the accused, but for the jury members themselves.

Behind the façade of their anonymity, these twelve ordinary people bring with them their own histories. Lives that are as complex as the trial, full of fractured dreams, shameful secrets, hope, fears, personal trauma and prejudice.
