Oxygen in the US has recommissioned Dorsey Pictures to produce a second season of true-crime show Accident, Suicide or Murder.

The series, which unravels the truth behind mysterious deaths, premieres Saturday May 9 at 6pm ET/PT.

Each hour-long episode takes a deep dive into suspicious deaths that were initially suspected as accidents, suicides or murders. With the families fighting for justice and the detectives on the case determined to find the truth, motives will be exposed, and justice will be served as the families finally find out what caused the death of their loved ones.

In the premiere episode, Ellen Greenberg was found dead in her locked apartment with over 20 stab wounds. But with no signs of an intruder or a struggle, detectives search for evidence and dig into Ellen’s mental health to determine her cause of death. After an initial ruling of her death, months later, a medical examiner stunned family members with a rare reversal, launching her parents into their own investigation to fight for justice for their daughter.

From twin sisters with a violent past with each other whose relationship is questioned when one sister is found dead in a car wreck in Maui, to a wife of an adulterous cop found mysteriously deceased, Accident, Suicide or Murder retraces an investigation from start to finish, taking viewers through the twists and turns of these shocking cases, from dissecting the red flags to the undeniable evidence, and strange behavior that put the tragedy in question.  Viewers hear from first responders, law enforcement, family members and those closest to the victims.

On the search for truth, not all cases end with the same determination, with many cases ending with controversial decisions. Many cases can be ongoing for months, years or even decades but with advances in technology, additional witnesses, exhumations, and newly discovered evidence, law enforcement are able to bring closure to the victim’s surviving family members and friends.

Accident, Suicide or Murder is produced by Dorsey Pictures,  with Chris Dorsey, Katie Hash and Betsy Rott serving as Executive Producers.
