A federal grand jury indicted the men on two counts -- conspiracy and interstate travel to damage and interfere with the operations of an animal enterprise. If convicted, prosecutors said, they face a maximum of five years in prison and a $250,000 fine for each count.
The indictment, which was unsealed after Lang's arrest, accused the pair of driving through Iowa, Wisconsin and Illinois in August 2013, with plans to damage animal farms. Prosecutors said that on Aug. 14, they stopped at a mink farm in Morris, Ill., that "was in the business of breeding, raising and selling mink to fur manufacturers."
There, prosecutors allege, the men released 2,000 minks from their cages and took down part of the fence surrounding the farm so the animals could escape. Officials also accused the pair of damaging the paint of two farm vehicles and painting "Liberation is Love" on a barn.
Prosecutors said the pair also had plans to hit a nearby fox farm located about an hour's drive away.
