The search for the missing Neenah man continues along the shoreline at Cave Point County Park.  According to a news release on Tuesday afternoon by the Door County Sheriff’s Department, heavy snow, rough waters and poor water clarity limited search efforts on Tuesday.  The missing man, 57-year-old Eric Richter, was reported missing late Sunday night after not returning home from taking photos earlier near a cliff at Cave Point.  The Door County Sheriff’s Office is asking people to avoid the shoreline at Cave Point County Park due to ice covered and slippery conditions.
