LA PORTE CITY, Iowa (KCRG-TV9) -- La Porte City police say large equipment has now broken up log jams on half of Wolf Creek. But they haven't released any new details in the case.___PREVIOUS STORY:Authorities were out Wednesday using some large equipment and an Iowa National Guard helicopter to search the Cedar River for a missing La Porte City teenager.
16-year-old Jake Wilson disappeared on April 7 when he left his family’s home to walk down to Wolf Creek in La Porte City. He has autism.
Black Hawk County Sheriff Tony Thompson said the weather and water levels were cooperating Wednesday. Workers used heavy equipment to break up log jams in Wolf Creek and the Cedar River.
Thompson said they also used a CS 47 helicopter to hover over the water, using the down draft to disturb the water in Wolf Creek, in the hopes it free an object trapped under the water. Two teams in kayaks made their way down the creek to see if it did.
The sheriff said he hopes by Monday the water level in Wolf Creek will have lowered enough to make sure things aren't being missed. He said because many areas are still flooded they will not be doing foot searches with volunteers yet.
