It has been five days since 22-year-old Gabby Petito was reported missing after she disappeared during a cross-country road trip with her 23-year-old fiancé, Brian Laundrie.

The couple set out on a trip from Blue Point, New York, to Oregon on July 2 in a white converted camper van. They had been in Petito's hometown to celebrate her younger brother's high school graduation.

Documenting their travels on social media along the way, the couple posted photos to Instagram indicated that they made stops in Kansas, Colorado and Utah.

But somewhere along their route in Wyoming, Petito's family lost contact with her. Ten days after Laundrie returned to the couple's shared home in North Port, Florida, with the van but without Petito, her family reported Petito missing to local police.

On Wednesday, Laundrie was officially named a person of interest in his fianceé's disappearance.

Local police said he is refusing to cooperate with authorities and is "hindering this investigation."

Laundrie has not been charged with any crime. The FBI and the Suffolk County Police Department in New York are assisting North Port police in its investigation.

Petito and Laundrie were high school sweethearts in Suffolk County at Bayport-Blue Point High School in Bayport, New York. In 2019, they moved from Blue Point to North Port to live with Laundrie's parents.
