Deer park &8212; Search and rescue efforts to find the missing body of Jeffery D. Hauer are still underway, causing family members to join the force.

Hauer, 35, of Natchez was last seen by residents of Deer Park in Old River yelling for help. The Concordia Parish Sheriff&8217;s department received the call at 2:15 p.m., May 30, reporting Hauer was thrown from his boat and now was nowhere to be seen.

Efforts including dragging the lake, visual inspection and the use of cadaver dogs have been unsuccessful. Weekend helicopter flights searching for the body have also seen nothing. Crews drug the river bottom again Monday, along with helicopter flights, revealing nothing.

Hauer&8217;s brother, Travis Bacon, returned home from Iraq Friday night and joined the search and rescue efforts. Bacon, currently working in Iraq as a contractor, was a search and rescue worker for the Navy. Sunday Bacon dove down deep into the waters of Old River in hopes of finding his brother.

Equipped with diving gear, Bacon said the visibility was minimal once in the water. He said depths reached 52 feet where the water temperature is around 65 degrees, 15 degrees cooler than surface temperature and a surface current and a under current were a factor.

Search and rescue efforts reach the one-week mark Tuesday and search and rescue officials say the search will continue.
