Darrell Garland told KXXV-TV his wife called saying she was going to the store to buy a cell phone battery. Then she asked what he wanted for supper. Garland said he didn't know but that he'd call back in a minute.
He says he tried calling her back but never got her again.
Garland says he's not sure his wife made it to the store.
Law enforcement officials have searched by helicopter while others have driven along the route she could have taken. Authorities also have checked credit card transactions and will watch store surveillance video.
