Robert Eugene Bennett, who has been questioned in the grisly disappearance of an acquaintance, was ordered held without bail Tuesday on a felony charge relating to fraudulent use of a Social Security number.

U.S. Magistrate Ronald Boyce said if the federal grand jury does not indict Bennett on the Social Security charge when it meets next week, Bennett will go free.Bennett, 51, of Kalamath Falls, Ore. - also known as Roy William Anderson - was questioned about the disappearance of Larry Duane White, 52. White is believed to be the person whose legs were discovered Feb. 22 in a trash bin behind Smith's Food King, 851 E. 45th South.

Boyce said Bennett was not to be released on bail because he has used aliases, has "traveled around" and the $1,000 in cash Bennett has is not enough to ensure his appearance for trial.

"Of major importance is the fact that there is an outstanding warrant . . . on a charge of bigamy," Boyce said. The warrant was issued in the Northwest.

Robert Van Sciver, Bennett's lawyer in the federal case, told reporters after the hearing that sheriff's detective Capt. Bob Jack questioned his client recently about White, but Bennett did not make a statement.

Bennett was arrested April 6 in Las Vegas and extradited to Utah.

The federal charge accuses him of fraudulently using a Social Security number in an attempt to obtain employment, said Assistant U.S. Attorney Bruce Lubeck.
