Ground search for couple in WA called off

The ground search for a missing couple in remote Western Australia has been called off but police say inquiries are continuing.

Raymond and Jennie Kehlet, 47 and 49, have not been seen since they were prospecting in the Table Top area in the state's Mid West region on March 22.

The alarm was raised more than a week later when their dog wandered into the Sandstone caravan park, about 25km from their campsite.

On Monday, police said they were suspending the ground search but any relevant information about the couple's whereabouts would be thoroughly investigated.

A post mortem is also being conducted on human remains found last week during the examination of a mine shaft within the search area.
