HILLSBORO – Vandals have caused an estimated $7,000 damage to signs on the farm belonging to a family of dwarfs featured on the reality TV show "Little People, Big World."
The damage occurred over the past two months at the Helvetia-area farm of the Matthew Roloff family, according to reports filed with the Washington County Sheriff's Office. The most recent incident happened last week.
The sheriff's office took reports on the incidents, but suspended their investigation because of lack of information about suspects. The Roloff family, however, has offered a reward for information leading to the arrests of the culprits.
The incidents began about two months ago, according to reports, when someone spread feces on the Roloff Farms sign on the property.
About two weeks ago, six holes were found in the sign and appeared to be caused by a hatchet or sledge hammer, wrote Washington County Sheriff's Deputy Amy Chewning. Chewning's report says the sign was also hit by two blasts from a shotgun last Wednesday.
Matthew Roloff also told deputies that 10 "Roloff pumpkin patch" signs had been taken in recent weeks.
Roloff's family is offering a $1,000 reward for information that leads to the arrest of those responsible for shooting their sign.
Roloff has dwarfism, as does his wife, Amy, and one of their children. Little People, Big World has been shown on The Learning Channel on cable television since spring of 2006. – John Snell
