Between 50 and 75 Oglala Sioux marched through Whiteclay, Neb., on Saturday, continuing their protests for the fifth week in a row.

The march was "real quiet and peaceful," said a dispatcher with the Nebraska State Patrol office in Scottsbluff.

The marchers left the Pine Ridge Indian Reservation at 12:43 p.m., reached Whiteclay by 1:15 p.m. and went back across the South Dakota border by 1:30 p.m., the dispatcher said.

Sioux leaders could not be reached for comment Saturday.

The Sioux say the marches are a demonstration against the sale of beer by Whiteclay businesses, the main suppliers to the nearby reservation, where alcohol is banned. They also are to protest the unsolved killings of two Oglala men.

The Sioux have promised to demonstrate every Saturday until liquor sales cease and the slayings of Wally Black Elk Jr., 40, and Ronald Hard Heart, 39, are solved.

On June 26, a grocery store that doesn't sell beer was looted and burned by a handful of protesters when more than 1,000 people marched on the village. On July 3, nine members of a crowd of 650 people were arrested on suspicion of disobeying a police order.

The protesters Saturday again threatened that "Whiteclay will be gone in two weeks," said Tim Hotz, who operates the Whiteclay Jack & Jill, which doesn't sell beer. During the July 10 march, marchers posted "eviction notices" on the Whiteclay stores that sell beer.
