Summary of “The FBI of the National Park Service”

A middle-aged couple from the Denver area, Harold and Toni Henthorn had been celebrating their anniversary with a weekend trip to Estes Park when their afternoon hike turned tragic.
In Harold’s car, which had been impounded right after the accident, an investigator found a park map with the Deer Mountain trail highlighted and an X marking the spot where Toni fell.
The elite special agents assigned to the ISB-the National Park Service’s homegrown equivalent to the FBI-are charged with investigating the most complex crimes committed on the more than 85 million acres of national parks, monuments, historical sites, and preserves administered by the National Park Service, from Alaska’s Noatak National Preserve to Hawai’i Volcanoes National Park.
The baroque, headache-inducing way jurisdiction functions in the United States means that, generally speaking, when crimes are committed on Park Service land, the county sheriff or local cops may not be in charge; the park service would be.
Several people had already told Shott and Grusing that Harold loved Panera, so the sandwich chain was one of their first stops when they visited the mall.
As the investigation uncovered more about Harold’s deceptions, some friends who had initially supported him slowly began to open up to Shott.
Shott laid out various pieces of the puzzle: her assessment of the scene, the time stamps on the digital photographs Harold took, and the text messages he sent.
We picked our way through the scrub, passing the flat spot where the FBI agents had camped out, and then the lunch spot, where the views Toni and Harold had enjoyed were spectacular.
