Petito had been traveling to a variety of national parks in Colorado, Utah and Wyoming with her boyfriend Brian Laundrie, camping in their converted van along the way. Petito was reported missing by her mother who stopped receiving regular calls from her daughter, and learned Laundrie showed up September first at his home in North Port, Florida alone in Petito’s van. A search is underway for Laundrie now who left his home September 14th.
