Agent Clay says this case is FBI jurisdiction because it occurred on the Appalachian Trail, the 2,200 mile long trail is managed by the National Park Service, about 60% of the trail is on land managed by federal agencies like the U.S. Forrest Service and Bureau of Land Management. Which means serious crimes committed on the trail fall under either full or at least joint federal jurisdiction, if a violent crime is committed on a part of the trail that isn't on federal land then the crime is jointly investigated by the FBI and the local state or county law enforcement.

Detective Silva says she did an NCIC offline search of police dispatch logs and found out that Chris' van was pulled over in Georgia the day prior to the attack, but that kind of information would not be available through the NCIC. The FBI's National Crime Information Center maintains a database of national crime statistics and information, an offline search is when law enforcement needs information that can't be acquired by using their online search engine, the information is manually searched for by an NCIC agent. However police departments do not upload their dispatch logs to the NCIC, nor would there be any information in the database about a traffic stop that didn't even result in a ticket. Only information about actual crimes is uploaded to the NCIC and unless it's a major crime like rape or murder there is often a delay of weeks or months between a crime being reported to local police and them uploading the information to the database, most law enforcement agencies simply don't have the time or manpower to upload non-urgent crime reports right away.
