BURLINGTON, Iowa (AP) — Authorities expect to resume their search for a boater missing after an accident on the Mississippi River near Burlington in southeast Iowa. The Iowa Natural Resources Department says the accident occurred Sunday when a boat went over the roller dam at Lock and Dam 18. The department says one boater grabbed a log and was rescued by a department officer. The department says the search for the other boater will resume Monday. The boaters' names aren't being released until relatives have been notified about the accident.
