NEW ORLEANS, La. – An Oklahoma woman who was lured over the Internet to take part in a Ku Klux Klan initiation was shot and killed after the ritual went awry, and the group tried to cover it up by dumping her body on a rural roadside and setting her belongings aflame, authorities said.

But the plan failed: By Tuesday, a local Klan leader sat in jail on a second-degree murder charge, and seven others were charged with trying to help conceal the crime.

"The IQ level of this group is not impressive, to be kind," St. Tammany Parish Sheriff Jack Strain said Tuesday.

The woman, whose identity was not released, was supposed to be initiated near the village of Sun, La. and then return to her home state to find other members for the white supremacist group, Strain said.

It wasn't clear what rites awaited her at the campsite, but authorities believe the initiation had begun by the time the shooting happened. Strain said the group's leader, Raymond "Chuck" Foster, 44, shot and killed her Sunday night after a fight broke out when she asked to be taken back to town.

Foster was charged with second-degree murder and is being held without bond. Capt. George Bonnett, a spokesman for the sheriff's department, said he doesn't know if Foster has an attorney.

Seven others — five men and two women ages 20 to 30 — were charged with obstruction of justice and were held on $500,000 bond at the St. Tammany Parish jail. All eight of the suspects live in neighboring Washington Parish, but Bonnett said he couldn't immediately identify their hometowns.

Authorities said some of the suspects tried to destroy evidence by burning the woman's belongings along with other items. At the campsite, investigators found weapons, several flags and six Klan robes, some emblazoned with patches reading "KKK LIFE MEMBER" or "KKK SECURITY Enforcement."
