James Louis Holland, already on death row in Utah for the murder of a man who picked him up hitchhiking, is scheduled to be sentenced Nov. 10 in an Idaho highway rest-stop slaying, officials said Friday.

Holland pleaded guilty earlier this week to first-degree murder in the July 4, 1987, slaying of Army National Guardsman Karl Behm. Under terms of a plea-bargain arrangement, prosecutors agreed not to seek the death penalty.Behm, 24, Highland Heights, Ohio, was shot twice and dumped at the so-called Juniper rest stop on I-84, about 10 miles northwest of Snowville, Utah, just north of the Idaho-Utah state line.

Florida police said Holland, Orlando, Fla., confessed to the Idaho killing and another death in Utah after he was arrested July 13, 1987, in Bonifay, Fla., for investigation of robbery.

Holland then was transferred to Utah, where he pleaded guilty Aug. 31, 1987, to capital murder charges in the July 5, 1986, shooting death of labor contractor Samuel Frank Patt, 70, Winter Haven, Fla., near Echo Junction, Utah.

Holland was sentenced to die by lethal injection in the Patt killing.
