Gabby Petito, a 22-year-old YouTuber and Instagram star, has been missing since late August, having embarked on a cross-country road trip with her fiancé Brian Laundrie, 23, that she was documenting on social media.
The couple grew up in Blue Point on Long Island in New York but lived together in North Port, Florida, setting out on a dream road trip from the Big Apple on 2 July in Ms Petito’s Ford Transit van and hoping to reach a friend’s house in Portland, Oregon, by Halloween.
However, Ms Petito’s family have not heard from their daughter since receiving text messages towards the end of last month that they have suggested may not have been written by her.
Mr Laundrie returned to North Port alone on 1 September.
Concerned for her daughter, Nicole Schmidt contacted police and a missing person’s investigation commenced on 11 September.
Here’s a timeline of everything we know about Gabby Petito’s disappearance so far:
