The Iowa Division of Criminal Investigation will join the search for a boat involved in a fatal crash two weeks ago today (Friday) on the Iowa Great Lakes. Jim Saunders, spokesman for the Public Safety Division, says they’re hoping to hear from anyone who was on the lake that night, or around its boat ramps. He says they’re also hoping to see anybody’s photographs or videos from that time frame, and are checking any local surveillance cameras that may have shown a lake view. He says they’ve gotten an average of about 30 calls a day from people trying to help. West Okoboji’s a big lake with many boats in the summertime, and Saunders says that’s part of the difficulty of investigating the case. He says they’re doing a forensic examination of the vessel that was hit and hope to be able to figure out from that where the boats were and which direction they were traveling when they collided. Then they’ll decide if it would help to have divers come in and search the area. The only description of the boat that left the scene of the collision is that it’s white, probably an inboard-outboard, and possibly had red stripes. Saunders says it looks to him like the impact was severe enough that there’s visible damage to the suspect’s boat, and that whoever was in that boat may have suffered some injuries themselves. Authorities are asking anyone to tell them what they know about people who were boating that night on the lake, especially if their boat’s suffered damage or they turn up with unexplained injuries. For now, the reward will remain at 25-thousand dollars. 51-year-old Michael Brosnahan of Perry was killed in the crash, and his wife was seriously injured.
