The Federal Bureau of Investigation has arrested the Ohio leader of the white supremacist group Aryan Nations on a series of federal weapons violations and for possession of a pipe bomb. Danny William Kincaid, 55, a convicted felon, has been charged with the illegal sale of at least 15 firearms, including assault rifles and shotguns. Following his indictment and arrest, local and federal law enforcement officials conducted a search of the home of a relative in Delaware, Ohio, that allegedly served as a weekly meeting spot for members of the white supremacist group. Kincaid's arrest on July 5 was the result of a 13-month FBI investigation, officials said. Acting on information provided by an informant, federal agents earlier searched Kincaid's home, where they allegedly found bomb-making materials and white supremacist literature linked to the Aryan Nations. In numerous reports, the FBI has traced the history and ideology of this militantly racist, anti-Semitic group which advocates the establishment of an all-white, racist state. Ohio Chapter Growth According to the FBI's current information on Aryan Nations, Danny William Kincaid and his wife, Kathy, took over leadership of the Ohio state Aryan Nations chapter in April 2000 and began trying to get it moving again. In a series of correspondence to members beginning in April, Kincaid and his wife describe their efforts to re-organize the state chapter. The Ohio chapter had remained largely inactive since the September 1997 arrest of its state leader, Harold Ray Redfeairn of Dayton, on a concealed weapons charge. In an April 2000 mailing, Dan and Kathy wrote to members asking for current information on them. "Sister" Kathy Kincaid wrote: "We are excited about cell group growth!! Just remember, you can make it happen with just a few like minded kindred. Pastor Dan will help you get set up. Let's fight the good fight and spread the gospel to our blinded brothers and sisters. Pastor Dan and I thank you in advance for your contributions to the church. Bless each and every one of you. Don't forget, I need your help! Help! Help! Help! Help! Help! Help! Help!" A June 2000 mailing from Dan Kincaid reads, in part, "After three years, we are trying to update all records on our members. Idaho has had some major computer problems and a lot of records have been lost. Since I am the state leader for Ohio, they have asked me to assist them by putting the state of Ohio records in order....This will give me a working knowledge of our members in Ohio and put the Chapter of Ohio Aryan Nations Church of Jesus Christ Christian back where it belongs by using the chain of command as it was intended from the very beginning." Kincaid has also helped to promote out-of-state meetings. He promoted a meeting of various "white power" groups held in September 2000 in Tennessee. In October of that same year, Kincaid had urged members of Aryan Nations to attend a Klan meeting in Greenville, Kentucky. According to the FBI's new report, Extremism in America: A Guide, Aryan Nations began a new effort to organize and recruit members in Ohio starting in 1997. For a time, the Ohio chapter -- one of the 18 "state offices" the organization now claims across the country -- seemed to be positioning itself as a possible new headquarters. Members held rallies and pursued fundraising in several Ohio cities; they also distributed anti-black and anti-Semitic fliers, especially targeting local rabbis and synagogues throughout northern Kentucky and southwestern Ohio. However, the chapter suffered a setback in September 1997 when Redfeairn was sentenced to six months in prison for carrying a concealed weapon. The recent loss of the 20-acre Aryan Nations compound in Idaho -- the group's national headquarters and home to the group's longtime leader, Richard Butler -- following a $6.3 million civil verdict has led to speculation that the hate group has been searching for new headquarters in another state, possibly Ohio. According to the indictment, Kincaid was convicted in 1965 on charges of firearms theft. In 1972, he pleaded guilty to drug charges in Tampa, Fla. and was placed on probation.
