Divers were not searching again Sunday, according to the Utah Department of Public Safety.
DPS divers worked with a Grand County team to search the Colorado River below Dewey Bridge on State Road 128, about 32 miles northeast of Moab.
Utah Highway Patrol Capt. Doug McCleve, the dive team's commander, on Sunday said the river was not deep, but the current and what he called "pitch dark" visibility made the search difficult. The dive team used sonar to identify objects that could be the footprint and then directed a diver crawling on his hands and knees to those objects.
"There are, as you can imagine, a lot of rocks down in the river bed," McCleve said.
McCleve said the dive team searched the area that was requested and there are no plans for the team to return.
The search commenced after a break in the case. Law enforcement found a suspect and discovered the footprint had been dumped below the bridge.
Law enforcement has not disclosed the name of the suspect. Rydalch, in an email, said no charges had been filed.
The footprint was one of about 20 in slickrock in the Hell's Revenge jeeping area near Sand Flats Recreation Area, just east of Moab. An off-road tour operator took visitors to see the print on Feb. 18, only to find it was gone.
