COUNCIL BLUFFS, Iowa – Officials with the Iowa Dept. of Natural Resources said Tuesday, that at around 7:40-p.m. Saturday, the Iowa DNR was dispatched to the west side of Lake Manawa near the entrance to the West Lake Village for a man that had been brought to shore by an individual on a personal watercraft after he was found in the lake.

Through the investigation, it has been determined that 54-year old Lawrence Wieneke, of Omaha, had somehow fallen into the lake from a personal watercraft operated by his wife, 59-year old Geralyn Wieneke, of Omaha, prior to a good Samaritan spotting Lawrence and bringing him to shore.

Lawrence Wieneke was transported to a Council Bluffs hospital in critical condition, but is expected to survive. Investigators believe alcohol may have been involved with this incident and toxicology results are pending. An investigation by the Iowa DNR Law Enforcement Bureau and the DNR State Parks Bureau continues, with assistance from the Council Bluffs Fire and Rescue and Council Bluffs Police Department.
