Ms Petito, 22, set off from her home in Long Island, New York, with boyfriend Brian Laundrie on 2 July for the adventure of a lifetime, taking in national parks and camping grounds across the United States.
The couple were seasoned travellers, and spent months preparing for the trip, converting a Ford Transit van and researching campsites and routes.
They documented the trip on their YouTube account Nomadic Statik, and on Instagram accounts.
But behind their seemingly picture-perfect lives, their relationship was under immense strain.
On 12 August, a witness called 911 to say he had seen Mr Laundrie hitting and slapping Ms Petito in Moab, Utah.
The couple were separated for the night, but police say they didn’t have enough evidence to press domestic violence charges.
Ms Petito suddenly stop communicating with her parents in late August. Her remains were located in the Bridger-Teton National Forest on 19 September after the case received enormous interest from media and online.
Mr Laundrie returned to his parent’s home in North Port, Florida, on 1 September, and ignored the desperate attempts from Ms Petito’s parents to make contact with their daughter.
He left his parent’s home on 14 September and is currently the subject of a nationwide manhunt.
Many questions are left unanswered by the case and what really happened between the pair before Ms Petito’s death.
