LA VISTA, Neb. (KMTV) - The Papio-Missouri Natural Resources District is joining the search efforts for a missing La Vista boy last seen on May 17.
The Papio-Missouri Natural Resources District is lowering the water level at the Walnut Creek Recreation Area to try and help find Ryan Larsen, an 11-year-old with autism.
Authorities said dive teams and search units finished preliminary searches there on Saturday night after focusing on the area for several days.
By lowering the water a few feet, authorities hope it will allow search teams better physical and visual access to the water at Walnut Creek.
Authorities said on Friday that Walnut Creek was being searched because Larsen and his family have visited there, and he wandered off there before.
Police said on Saturday that a K9 picked up a scent at Walnut Creek but it was unclear what kind of scent it was.
"This scent may be animal, human, or otherwise. This is a vast park with extensive area to cover including water, vegetation, tall grasses, and miles of trails," police said in a release on Saturday afternoon.
Larsen has brown hair and hazel eyes. He is 5-foot-8 and weighs approximately 125 pounds. He was last seen leaving La Vista West Elementary around noon on May 17,
