(New Paris, OH)--Crews continued Monday to search for a missing man on a private Preble County lake.  More information released Monday indicated that the missing person is a 20-year-old male who had gotten into a kayak and gone onto the lake on Guy Murray Road in the dark early Sunday morning.  A witness saw the kayak overturn and tried for about 20 minutes to locate the person before calling for help.  Monday, crews used watercraft with sonar, drones, and K-9 units but were unsuccessful in locating the missing person.
