FBI agents arrested Michael Conrade Sibley, 67, of Marietta, Ga., after he allegedly confessed to leaving two homemade pipe bombs in a backpack at Vickery Creek Park in Roswell in November 2014, and charged him with attempting to damage federal property. Sibley, who described himself as a “patriot,” is said to have also put in the backpack a Koran, a book about Kuwait and a map with a Jewish center in Atlanta circled, along with writing a Muslim-sounding name on its label — an apparent attempt to frame Muslims for an attempted terrorist attack.
Steven Timothy Snyder, a 38-year-old Michigan man believed to have been a member of a violent skinhead gang called the Fond du Lac Boot Boys in his teens, robbed a bank in Wausaukee, Wis., apparently killed a 59-year-old man he encountered while fleeing, and then died in a shootout in Fond du Lac with Trevor Casper, a 21-year-old state trooper who was also killed. A man with the same name and birth date as Snyder was arrested in March 1996 after attacking a Fond du Lac home. He was tattooed with the words “White Power” and was carrying literature from the National Alliance, the leading neo-Nazi group of the period.
Genesee County, Mich., officials announced the arrest of a couple, both of them local school bus drivers, for embezzling at least $50,000 from the woman’s mother and using it to amass an arsenal of 30 weapons, including a .50-caliber machine gun and 17,000 rounds of ammunition, hidden in a secret basement bunker. Steven and Sarah Nick of Davison Township were tied to the Southeast Michigan Volunteer Militia and had marked a bulletproof vest with the words “We Kill For Peace.”
Two men who worked for the Florida Department of Corrections in Lake Butler and were also members of the Traditionalist American Knights of the Ku Klux Klan pleaded not guilty to conspiring to murder a black former inmate with whom they had quarreled. Charles Newcomb was a dismissed corrections trainee and David Moran was a correctional officer before their arrests. A third man, a guard and Klan member named Thomas Driver who had worked with Moran at the DOC’s Reception and Medical Center, was arraigned earlier on the same charges.
Rejecting arguments that he had been led astray by his older brother, a federal jury sentenced Dzhokhar Tsarnaev, 21, to death in the Boston Marathon bombing. The attack, which left three dead and more than 260 wounded in April 2013, was meant as retaliation for what Tsarnaev reportedly called “U.S. crimes” in Muslim countries like Iraq and Afghanistan. His older brother, Tamerlan, died during the attack.
Two members of the St. Louis chapter of the New Black Panther Party pleaded guilty to conspiring to use bombs to attack the police chief of Ferguson, Mo., the St. Louis County prosecuting attorney, and a local police station during protests over the August 2014 shooting of Michael Brown by a Ferguson police officer. Brandon Orlando Baldwin, 24, and Olajuwon Davis, 23, were each expected to be sentenced to seven years in prison after agreeing to plead guilty to four felony counts.
A man with an 18-year history of hating the government killed his wife, three small children and himself in their remote cabin in Montana’s Beaverhead-Deerlodge National Forest.

A father and son, described by the local sheriff as “anti-police, antigovernment, radical extremists,” allegedly lured a 70-year-old, armed Yavapai County, Ariz., Sheriff’s Office volunteer to their home and shot him three times.

The motive was unclear, but officials found a marijuana farm at the Niedermeyer home.
The FBI arrested three men in Phoenix who allegedly were planning to steal drugs and money from cartel members trafficking across the Mexican border.
