Former FBI agent says Brian Laundrie will likely be found in his 'comfort zone'

Former FBI agent Terry Turchie says fugitives like Brian Laundrie "tend to try to figure out" how they can reach their "comfort zone" while on the run and are often located in those places.

"People don't change because they become a fugitive," Turchie, who spent a year in the North Carolina mountains between 1998 and 1999 leading the fugitive case against Olympic bomber Eric Robert Rudolph, told Fox News Digital. "They tend to try to figure out how they can land in the comfort zone."

Laundrie enjoyed hiking and traveling, so some experts have suggested he may be in the wilderness or on the road, and several potential sightings have added some credibility to those theories. Others have suggested the fugitive may be closer to home and could be getting help from another person.

Laundrie's sister Cassandra Laundrie described her brother in an interview with media as a "mediocre" survivalist.
