ROCKPORT, Summit County — A man reported missing on Sunday showed up at home Thursday, not even realizing that he was "missing."

Halden Efren, 20, originally from Micronesia, was camping in Rockport State Park when he walked away from the area Sunday after getting into an argument with his girlfriend, said Summit County Sheriff's Sgt. Ron Bridge. Because he had only been in the country a month, friends were concerned that he did not know the area well or speak English well.

About 20 Summit County search and rescue workers and a Utah Department of Public Safety helicopter looked for the man on Sunday. The search extended into Evanston, Wyoming, after an eyewitness reportedly saw a man matching Efren's description walking along I-80.

But on Thursday, Bridge said family members called the sheriff's office to tell them Efren had returned home after simply staying with friends for a few days, completely unaware of the search effort.

"He's just been walking around, hanging out with other friends, didn't know he was missing," Bridge said.

Efren was captured on surveillance video from a 7-Eleven store near Rice-Eccles Stadium about three hours after he walked away, he said. The report of him being in Wyoming turned out to be false.
