Gabby Petito

Gabby Petito and her boyfriend Brian Laundrie embarked on what should have been a life-changing cross-country trip, but only one of them returned home. 

Vincent Abolafia and Kaileigh Catalano were found safe in New York City following a plea for help from Gabby Petito's father Joseph Petito.

Vincent Abolafia and his girlfriend, Kaileigh Catalano, both 15, were last seen Thursday at a train station bound for New York City.

“The Murder of Gabby Petito: Truth, Lies and Social Media” will examine "Gabby’s life through the curated lens she created and immerses the viewer in the world of social media sleuthing that was crucial to the case," according to Peacock.

Gabby Petito's father Joe had put out a plea to help find Melissa Molinari after the mother of four vanished four days before Thanksgiving.

Lateche was last spotted at a 7-Eleven after flying to California to see her boyfriend Joseph Smith, with whom she'd allegedly had several recent domestic violence altercations. 

Laundrie family lawyer Steven Bertolino told Oxygen.com that Brian Laundrie's parents noticed that a gun was missing from their possession when they reported their son missing.

Brian Laundrie was a person of interest in the disappearance and murder of his fiancée, Gabby Petito. 

“It’s about the changes we can make. We can’t change the past, but we can change the future,” Gabby Petito’s mother, Nichole Schmidt, said of the vision behind The Gabby Petito Foundation.

“Yes, we made a mistake, it was human error, but I still stand behind my team," North Port Police Chief Todd Garrison said of investigators mistaking Brian Laundrie's mother for the missing 23-year-old.
