The last of five suspects in a failed plot to bomb a highway bridge near Cleveland was convicted Thursday on all counts.
The verdict followed a three-day trial in which Joshua Stafford of Cleveland acted as his own attorney.
Stafford, 24, was convicted of two counts of using weapons of mass destruction and one count of explosive materials. He is to be sentenced Sept. 11. Under federal guidelines, he could get a prison term between 30 years and life.
Earlier Thursday, Stafford posed questions to himself and testified he was unaware friends from the anti-corporation Occupy Cleveland movement planned to blow up the bridge between Cleveland and Akron.
Prosecutors said Stafford tried to use his cellphone to detonate the explosives, not knowing they were fake.
No bomb went off and no one was injured in the plot. The intended target was a highway bridge over the Cuyahoga Valley National Park between Cleveland and Akron.
U.S. Attorney Steven Dettelbach praised FBI investigators who broke up the plot. The government described the suspects as self-proclaimed anarchists who acted out of anger against corporate America and the government.
