On July 4, 2021, Gabby and Brian embarked on a cross-country exploration that consisted of visiting various National Parks. However, the concern began when Laundrie arrived back to his home in North Port, Florida on September 1, 2021, more than a month sooner than anticipated. However, Gabby was not with him. It was ten days after that, on September 11, 2021, when Petito's family realized that Gabby was officially missing. When the police arrived to the house of the Laundrie family, they were greeted with a piece of paper that had the phone number of their family lawyer. They immediately were uncooperative, Brian included.
