Watauga County and Avery County law enforcement officials have confirmed that they have received tips regarding Brian Laundrie's whereabouts.
It was confirmed to WSOC-TV that the North Carolina authorities had received over half a dozen tips earlier in the week about potential sightings of Laundrie, who is a person of interest in the disappearance of his fiancée Gabby Petito.
The callers suggested that Laundrie, who has been missing since September 14, was hiding out on the Appalachian Trail.
"It's a rugged trail, but it is easily accessible and you get back in there and you could pretty much hide anywhere," a local hiker named Tom Niziol told ABC 11. "So if somebody wanted to hide in this area, they might be able to."
Following the influx of tips given to authorities in North Carolina, Watauga County officials even pulled over a vehicle to investigate a potential lead in the area.
However, they found nothing relevant to the case at hand. Law enforcement said social media posts are being monitored in case anything of interest arises.
Petito and Laundrie had embarked on a cross-country road trip when the former suddenly disappeared.
On September 11, Petito's parents reported her missing after Laundrie returned to his Florida home without her less than two weeks earlier.
On September 19, the FBI confirmed in a news conference that human remains were located in a campsite in Teton County. The body was said to be "consistent with the description" of the missing 22-year-old travel blogger.
The authorities had been awaiting full forensic identification of the body and on September 21, it was confirmed that the remains belonged to Petito.
Laundrie, a person of interest in the case, has been missing himself since September 14, his parents told investigators.
Although he has not been charged in connection with the death of his fiancée, which has been ruled a homicide, he has been indicted by a federal grand jury for allegedly using a Capital One Bank card he was not authorized to use.
He has been accused of spending $1,000 on the card between August 31 and September 1, The Guardian reports.
