AKRON, Ohio – Federal investigators released FBI surveillance video of three men trying to blow up the Brecksville-Northfield high level bridge in April of 2012.
The bridge carries Route 82 over the Cuyahoga Valley National Park.
"Make no mistake, these individuals intended to do our community harm, and they operated as the evidence showed: in a calculated and callous manner," Stephen Anthony, FBI Special Agent in charge, said on June 14.
Douglas Wright, Brandon Baxter, Anthony Hayne, Connor Stevens and Joshua Stafford were all convicted.
At least three are self-proclaimed anarchists, who wanted to use violence to bring down the government and American financial institutions.
In the video, the men thought they were planting real bombs, but the bombs were fake explosives sold to them by an undercover FBI agent.
After the men planted the fake explosives, investigators said they repeatedly used a cellphone to call a number that they believed would detonate the bombs.
The only thing that blew up was the plot.
Four of the men plead guilty to federal charges, including conspiracy and attempted use of weapons of mass destruction, and will spend between 6 and 11 years in prison.
Stafford was convicted by a jury. He will be sentenced on September 11. He faces up to 20 years in prison.
