A documentary about Gabby Petito’s killing is coming this month

A heartbreaking case.

A new documentary is coming to TVs this month and is set to explore Gabby Petito's homicide case, with her family opening up about her tragic death. Coming to Peacock on 17 December, the trailer for The Murder of Gabby Petito: Truth, Lies and Social Media has just been released, showing her parents speaking out publicly about her death. "It was like every parent's nightmare in just a flash of a second," Gabby's stepdad Jim said in the preview. "She's gone, she's missing." "The thoughts that were going through my head were that something really bad has happened to her," her mother Nichole added. "It's still unbelievable. I don't understand it." Gabby was reported missing on 11 September, ten days after her fiance Brian Laundrie returned to Florida alone after the pair had embarked on a summer cross country road trip, starting in New York. Her body was found on 21 September at Grand Teton National Park. Her death was later ruled a homicide by the FBI, revealing she had died as a result of strangulation manually. Brian himself then went missing, telling his parents that he was going for a hike in the Carlton Reserve in Florida but never came home, despite then being a person of interest in the missing persons case. His body was then found on 20 October and it was later announced that he died of a self-inflicted gunshot wound. The TV special is not the first time the family has opened up about Gabby's passing, with her mother Nichole telling Dr. Oz that despite alleged domestic violence, they never saw anything suspicious with Brian. "I don’t know why Gabby didn’t open up to me about certain things," Nichole said. "We just didn’t see any red flags."
