SMYTH COUNTY, Va. -

More than a hundred mailboxes have been vandalized in Smyth County, Virginia. Vandalizing mailboxes is a federal offense and the Smyth County Sheriff's Office is asking the public for help locating who may have done this.

Residents told us the vandalism has been going on for years. There are mailboxes smashed in and torn off their posts on Riverside Rd. and Scratch Gravel Rd. The Sherriff's Office said the damage also extends down Old Airport Rd., Southfork Rd., Hiler Bridge Rd., Red Stone Rd., Adwolfe Rd., and Stoney Battery Rd.

Lonnie Dunavan has lived on Scratch Gravel Rd. for 35 years and told us this is something he's come to expect.

"It could be a month or two and then they may come through again pretty quick," he said. "You never know when they're going to hit next."

Dunavan told us he's been a victim of the vandalism a couple of times before.

"It's sort of discouraging and everything because you pretty much know what's happened," he said.

Dunavan told us the vandals strike at night. Tuesday and Wednesday nights were no different with 116 people calling to report mailbox vandalism, according to the Sheriff's Office.

"They got my neighbors down here and on the other side of the hill," Dunavan said.    

Across the county, new posts are going in as residents try to keep this from happening again.

Dunavan said, however, after years of spending 40 to 60 dollars for each new mailbox, he's learned to leave his old one up in an effort to discourage the vandals as much as they've discouraged him.

"They just think, I guess, it's funny," Dunavan said. "They get a kick out of it and everything, which it's not funny to everybody else."

The Smyth County Sheriff's Office asks that you call at (276)-783-7204 if you have any information about the vandalism.
