Utah County sheriff officials had no leads Friday morning toward finding the traveling companion of the youth who on Wednesday led officers on a one-hour chase over icy roads at speeds of up to 100 mph.

Deputies answered a call about a suspicious vehicle near the Bergin mine, west of Elberta, at 11:53 p.m. Wednesday. An adult male left the vehicle and fled on foot, but the driver rammed a sheriff's car and sped south on U.S. 6.Juab County deputy sheriffs set up a roadblock, which the driver evaded. The 46-mile chase ended in Lynndyl, Millard County, when the driver stopped just short of a tire-slashing road block.

A 17-year-old is being held in the Utah County youth home. He is wanted in Winnemucca, Nev., for vehicle theft and in San Jose, Calif., on separate charges.

Utah County sheriff's officials still are searching for the youth's traveling companion, identified as Wayne Palmer. Palmer is in his 20s and is 180 pounds, 5 feet 9 inches, blond and was last seen wearing a green baseball cap, a green shirt and black jeans.
