TAMPA, Fla. (WFLA) — This past Monday, Netflix released a new documentary detailing the events leading up to and during the investigation of Gabby Petito’s murder at the hands of her fiancé, Brian Laundrie.

“American Murder: Gabby Petito” features testimonies from people who knew the young couple before their deaths in 2021 — including Gabby’s parents, Joe Petito and Nichole Schmidt.

Throughout the investigation, 8 On Your Side followed every step as investigators across the country worked to find the 22-year-old vlogger and, later on, her fiancé-turned-killer. We’ve compiled a list of stories to review before watching the documentary.

The police encounter before Gabby’s Disappearance

A month before Gabby Petito was reported missing, she and Laundrie were spotted in Moab, Utah, when police responded to a domestic incident between the couple.

At the time, police stated that the couple argued and hit each other. When officers arrived, they found Gabby in tears, as seen in body cam video.

“Yeah, I don’t know, it’s just some days, I have really bad OCD, and I was just cleaning and straightening up and I was apologizing to him saying that I’m so mean because sometimes I have OCD and get frustrated,” she said.

“I’m not going to pursue anything [criminal charges] because she is my fiancé and I love her. It was just a squabble. Sorry it had to get so public,” Laundrie told police later in the video.

A report filed by another police agency alleged that Moab police missed red flags in the incident, and while Gabby Petito was the predominant aggressor in the argument, she was “very likely” a victim of long-term domestic violence.

Gabby’s disappearance and death

Questions about Gabby’s safety arose when Brian Laundrie returned home to his parents’ house in North Port from the couple’s cross-country trip — this time without Gabby.

Gabby’s family reported her missing on Sept. 11, 2021, but on Sept, 19, 2021, her body was found in the Wyoming wildnerness.

About a month later, Teton County Coroner Dr. Brent Blue confirmed that Gabby was strangled to death and left at a campground in Grand Teton National Park. According to Blue, she was left there for three to four weeks before authorities found her.

Brian Laundrie’s suicide confession

Shortly after Gabby was reported missing, her fiancé followed suit — leaving the home of his parents, Christopher and Robert Laundrie, and fleeing to the Carlton Reserve in Sarasota County.

At the time, Brian Laundrie was not considered a suspect in Gabby’s murder, but a federal arrest warrant was issued for him after he illegally used her Capital One Bank card.

Laundrie would remain missing for weeks until his skeletal remains were in the Carlton Reserve. The FBI used dental records to confirm the remains belonged to Laundrie, who killed himself with a gunshot to the head.

When his remains were found, investigators also found a backpack and notebook that contained a confession.

In it, Brian admitted to killing Gabby and that he couldn’t live without her.

“I ended her life,” Laundrie wrote in the notebook. “I thought it was merciful, that it is what she wanted, but I see now all the mistakes I made. I panicked. I was in shock. But from the moment I decided, took away her pain, I knew I couldn’t go on without her.”
