Gabby Petito Documentary Premieres 89 Days After She Was Found

Gabby Petito’s parents and step-parents are having to relive their worst nightmare.

Earlier this year, Nichole and Jim Schmidt, and Joe and Tara Petito, reported their daughter missing after she took a cross-country road trip with her fiancé, Brian Laundrie.

On September 11 Gabby was reported missing, and a week later their worst nightmare became a reality.

“The thoughts that were going through my head were something, something really bad has happened to her,” Nichole recalled.

Gabby’s remains were discovered in Bridger-Teton National Forest on September 19, two days later, the remains were identified as the 20-year-old.

Her death was ruled a homicide and the manner of death was strangulation.

A first look at the Peacock documentary, “The Murder of Gabby Petito: Truth, Lies and Social Media,” shows the Petito-Schmidt families reflecting on their daughter’s life, death and legacy.

On December 17, viewers will get to see her parents look back on her childhood memories and uncover details never seen before.

"It was like every parent’s nightmare," Gabby's stepfather, Jim, recalls in the trailer. "Just like, in a flash of second. She's gone, she's missing."

Laundrie was the only person of interest in her disappearance and death.

Unfortunately, he took his own life in October leaving this tragedy an open-ended mystery.

"It's still unbelievable," Nichole says in the trailer. "I don't understand it."

Gabby’s father has been a major advocate for finding missing persons since the disappearance and murder of his daughter.

“Everybody deserves to feel safe at home. Everybody deserves to be found that is missing. Everyone,” Joe demands.

Since their daughter’s passing, the Petito-Schmidt family started the Gabby Petito Foundation.

“No one should have to find their child on their own. We are creating this foundation to give resources and guidance on bringing their children home,” Joe wrote on Twitter when he announced the foundation.

In November, Gabby’s parents gave their first live interview with WFLA NOW and spoke about their plans for the foundation.

“For me, preventing this from happening to someone else, if we can try and make that change, that’s justice for me. It’s helping others,” Nicole said. “It’s about the changes we can make. We can’t change the past, but we can change the future.”

Gabby’s mother, father and stepmother discussed how they’re working to create a type of AMBER Alert for domestic violence victims and missing persons for people aged 18-64 years old.

Joe expressed this type of alert should be on a national level, but currently isn’t.

Nichole added that if a family knows their loved one is missing, the alert can help people start looking for them immediately.

At the end of the day, Joe, Tara and Nichole want to do right by Gabby and make her proud.

“I want to make sure Gabby is looking down and saying ‘I’m Proud,’” Joe said.
