Meanwhile, the FBI in Denver said Saturday that agents were conducting ground surveys at Grand Teton National Park in Wyoming, with help from the National Park Service and local law enforcement agencies, seeking clues to Petito's disappearance. Her last known contact with family members was from the national park known for its mountainous terrain. Police said Laundrie was alone when he drove the van back to his parents’ home in North Port, Florida, on Sept. 1. Earlier in the week, Petito's family pleaded for the Laundrie family to tell them where their son last saw her. His parents later moved to North Port, about 35 miles (55 kilometers) south of Sarasota.
