MOAB- — The search for a Texas couple who disappeared east of Moab has turned into a recovery operation, according to the Grand County Sheriff's Office.

On Friday evening, the office said that although search and rescue crews had not yet found the bodies of Ray and Maranda Ankofski, they were now moving from search and rescue to body recovery.

“Despite extensive efforts, including the use of advanced search techniques and resources, Ray and Maranda Ankofski could not be located,” the sheriff's office said in a press release. “… based on evidence at the scene (and) during the operation … the Grand County Sheriff's Office is seeking closure for the family and friends (of the couple).”

On June 21, the Texas couple set out on the Steel Bender off-road trail, but did not return as planned and their vehicle was found abandoned.

On Wednesday, the Grand County Sheriff's Office told KSL TV that they found a pair of pants within the search radius that contained Ray Ankofski's wallet and identification.

The office reported that rescue crews believe the couple may have been caught in a flash flood and swept away.
