PINE RIDGE, S.D. (AP) — An annual Justice March from Pine Ridge to Whiteclay, Neb., to honor and remember two men found dead is slated for Saturday.

The bodies of Wally Black Elk Jr., and Ron Hard Heart were discovered June 8, 1999, near Whiteclay. Their deaths are unresolved.

Oglala Sioux Vice President Tom Poor Bear is Black Elk’s brother and Hard Heart’s cousin. Poor Bear has organized a march every year since 1999 to bring awareness to their unresolved deaths.

Saturday’s march will start at 12 p.m. at Billy Mills Hall in the village of Pine Ridge. Supporters will then trek two miles to cross into Whiteclay.
