Watauga County deputies even pulled over a car to investigate a possible lead, but it turned out to be nothing.
Investigators said they are monitoring postings online and staying in close contact with federal authorities.
Laundrie has no known connections to western North Carolina. Still, hikers know the Appalachian Trail provides a good hiding spot.
Laundrie has not yet been charged in connection to Petito’s murder, but a federal grand jury indictment filed in U.S. District Court in Wyoming alleges Brian Laundrie used a Capital One Bank card and someone’s personal identification number to make unauthorized withdrawals or charges worth more than $1,000 during the period in which Petito went missing.
It does not say who the card belonged to.
The reward for information that leads to his arrest has ballooned to more than $100,000.
