Here's everything you need to know about the documentary.

What happened to Gabby Petito?

In September 2021, 22-year-old Gabby Petito was reported missing by her family in September after she embarked on a "dream" cross-country trip with her fiancé Brian Laundrie back in June.

Laundrie had returned to the couple's North Port, Florida, home in early September, however, he wasn't with Petito, and roughly two weeks later, he disappeared, sparking a weeks-long search for him.

Days into the search for Laundrie, authorities discovered Petito's remains in Wyoming and a coroner ruled her cause of death to be strangulation.

Local and federal authorities later revealed they'd found Laundrie's remains after searching through a 25,000-acre reserve in Florida. A medical examiner ruled he died by suicide. According to the FBI, authorities found a notebook near the scene, in which Laundrie claimed responsibility for Petito's death.
