AKRON, Ohio — Three self-described anarchists pleaded guilty on Wednesday in an Ohio federal court to plotting to blow up a four-lane highway bridge near Cleveland in April, authorities said.

Douglas Wright, 26, Brandon Baxter, 20, and Connor Stevens, 20, all pleaded guilty to conspiracy to use a weapon of mass destruction, attempted use of a weapon of mass destruction and attempted use of an explosive device to destroy property used in interstate commerce, authorities said in a statement.

The three guilty pleas came before U.S. District Judge David Dowd Jr., who expects to sentence the men in November. All three had been scheduled to face trial on September 17.

A fourth suspect, Anthony Hayne, 35, pleaded guilty in July to the attempted attack and agreed to testify against the others. The fifth suspect, Joshua Stafford, is undergoing competency testing.

In July, Hayne said he understood his plea meant that he would face more than 15 years in prison and possible probation for life.

On Wednesday, lawyers for Wright, Baxter and Stevens argued that their clients should not face enhanced sentences on the charges. The so-called terrorism enhancement calls for a minimum sentence of 30 years in prison and up to life.

Without the enhancement penalty, the three men face a minimum of five years in prison.

With short haircuts, and clean shaven, the men looked far different at Wednesday’s hearing than they did in the mugshot photos from their arrests.

“The bottom line was he wanted to get the least amount of time,” said Defense Attorney Terry Gilbert, of his client Connor Stevens.

“You just don’t know what a jury is going to do,” said John Pyle, who represented Brandon Baxter.

An undercover FBI agent sold the men inoperable detonators and plastic explosives and authorities arrested them on April 30 after determining that they planned to proceed with the attack.

According to an FBI affidavit, authorities paid a criminal informant more than $5,000 as part of their investigation into the group, when the informant met the five men at an anti-Wall Street Occupy Cleveland rally in October 2011.

U.S. Attorney Steven Dettelbach told reporters after the hearings on Wednesday that his office was not spying on protest groups such as Occupy and did not entrap the five men.

“Make no mistake; it was their plot,” Dettelbach said.

Defense attorneys had questioned the role of the paid informant and plan to raise those questions again at sentencing.

Speaking to NBC station WKYC, Stevens’ mother Gail Stevens described the FBI’s involvement in the case as “freaking evil.”

Supporters say they want to hear how these “kids” got in over their heads, and what role the FBI played in this plot.

“We very much want this story to be told,” Gail Stevens added.
