Prosecutors say Dibee was a member of the Earth Liberation Front and Animal Liberation Front, which the U.S. Department of Justice has held responsible for acts of domestic terrorism.
An environmental and animal rights activist pleaded guilty Thursday to decades-old federal arson charges, including involvement in a 1997 central Oregon fire that destroyed a slaughterhouse.
Prosecutors say Joseph Mahmoud Dibee, 54, was a member of the Earth Liberation Front and Animal Liberation Front, which the U.S. Department of Justice has held responsible for acts of domestic terrorism.
Dibee pleaded guilty to arson and conspiracy to commit arson for his role in the fire that destroyed Cavel West, a slaughterhouse that processed and sold horse meat in Europe.
