In a surprise move, Douglas Wright, of Bloomington, pleaded guilty Wednesday to conspiring to use a weapon of mass destruction, knowingly attempting to use a weapon of mass destruction and attempting to damage property with explosives.

Two other men charged in the scheme also pleaded guilty. A fourth man pleaded guilty earlier this year. That leaves one suspect facing possible trial.

The FBI has said the public was never in danger even though they say the target was a highway bridge over the Cuyahoga Valley National Park between Cleveland and Akron.
