The family of a clerk who mysteriously disappeared along with his car and about $4,000 from a Salt Lake County gas station say they "have total faith" in the man's safe return.

Robert E. Lindsay, 28, was discovered missing from a Taylorsville Phillips 66 gas and convenience store early Thursday morning."This is the hardest thing we've gone through," Lindsay's stepmother, Bonnie, said. "We love him and want him back; we're praying for his safe return as soon as possible."

A deputy's report said the manager found the store locked, all the lights turned off, and a note on each door saying it was closed but would open again at 6 a.m.

About $90 from a cash register and more than $3,000 from two combination safes were missing, according to the report. Store shelves were freshly stocked and there were no signs of a struggle.

The police report classifies the incident as a "theft/possible embezzlement or abduction."

However, detectives continued Saturday to treat the disappearance as a robbery-kidnapping and have issued a nationwide all-points bulletin with a description of Lindsay and his car.

Locally, deputies and detectives scoured the airport, train station and bus stations for Lindsay's car.

"We still haven't located the car. We're searching again, and trying to piece together what happened between 2 a.m. and 5:30 a.m.," Detective Daryle Ondrak said.

A newspaper delivery driver, who asked not to be identified, said Lindsay waved at her between 1:45 a.m. and 2:15 a.m. when she stopped to fill newspaper stands at the store.

Lindsay worked at American Express during the day and had recently received a promotion and pay raise, according to the report.

A secretary at American Express said she had not heard from or seen Lindsay Friday morning, the report said. He usually arrived at work about 8 a.m.

Lindsay's wife told deputies she talked with him about midnight and "everything appeared to be fine."

Lindsay is a nephew of Richard P. Lindsay, a member of the Second Quorum of the Seventy of The Church of Jesus Christ of Latter-day Saints.

He is described as white, 5 feet 9 inches, 200 pounds, with a very heavy build and brown hair parted on the right side.

The car is a 1986 burgundy Toyota Corolla, bearing Utah license 751BVW.
