Five juvenile members of the LeBaron polygamist clan were to appear in U.S. District Court in Salt Lake City Wednesday prepatory to their appearance before a grand jury investigating the 1987 slaying of former LeBaron follower Daniel Ben Jordan.

The five were brought to Utah from Chicago, where they were taken into custody last month along with four adults.Some of the youngsters were in the deer-hunting camp in Sanpete County on Oct. 16, 1987, when Jordan was shot to death.

Also present was Aaron LeBaron, 20, who was in custody in Chicago on charges of transporting illegal aliens.

Aaron LeBaron led a small band of children from the LeBaron ranch in Sonora, Mexico, to Jordan's polygamist compound in Bennett, Colo., a few weeks before the slaying.

The night of Jordan's funeral, Aaron LeBaron gathered Jordan's clan and proclaimed himself their new patriarch, authorities said.

He was taken into custody after weapons were drawn, but the charges were dropped and he and the LeBaron children disappeared the same night from various Denver-area foster homes.

Federal authorities believe the youngsters may have pertinent information that could result in indictments against Jordan's killer - if the children will talk.

The five juveniles are named in grand jury material witness warrants. Testimony in U.S. District Court in Chicago indicated the Utah grand jury will convene Thursday and Friday.

Utah FBI agents, testifying Monday at the removal hearing in Chicago, said the children had been talking to authorities. Defense attorneys complained that the youngsters had not been properly informed of their rights before questioning.

On June 28, 1988, three former LeBaron clan members - Mark and Duane Chynoweth and Eddie Marston - were shot to death in Houston and Irving, Texas, along with Duane Chynoweth's 8-year-old daughter.
