WICHITA, Kan. (KSNW) – Gabby Petito made a stop in Kansas while on a cross-country journey in a converted camper van with her boyfriend, Brian Laundrie, to visit national parks in the U.S. West. The trip started July 2 from New York.

One of the stops was south of Oakley at Monument Rocks, which was designated as the first National Natural Landmark in 1968. Petito was photographed under the landmark according to an Instagram post made on July 4.

On Sunday, authorities say they had discovered a body believed to be Petito’s while searching campsites on the edge of Grand Teton National Park, which the couple had visited. The FBI confirmed in a tweet on Tuesday it was Petito’s body.

During the trip, the two got into a fight along the way, and Laundrie was alone when he returned in the van to his parents’ home on Sept. 1, police said.

Laundrie has been named a person of interest in the case, but his whereabouts in recent days were unknown.

The FBI and police Monday swarmed his home.

Petito and Laundrie were childhood sweethearts who met while growing up on New York’s Long Island.
