Rice County Sheriff Troy Dunn joined us on the KDHL Newsline during the 8:05am report this morning and re-iterated his office's hopes that people could assist in locating a man who's picture people couldn't identify.   Sheriff Dunn told us later in the day the man came forward and is cooperating with his office and is not a suspect in the case. On July 23 the Sheriff says his office received a call from woman who had been drugged with Rohypnol at a gathering in Northfield.  Rohypnol is also referred to as a date rape drug.  The incident happened on July 16 at the Red Barn Farm during a large get-together.  A number of women involved in a book club were there and an Owatonna woman suddenly appeared to be very intoxicated.  She became unresponsive on the way home and the ladies with her immediately phoned 911.  They were instructed to take her to District One Hospital in Faribault and she was then airlifted to St. Mary's Hospital in Rochester where she remained unresponsive until late the next morning.  Doctors there were reportedly baffled after running many tests to determine what happened and then the drug results came back July 23 confirming she had ingested a potentially lethal dose of Rohypnol.  There was no indication of any type of physical assault.  Authorities are still hoping anyone with information will call the Rice County Sheriff's Office Investigations Division at 507-334-4391 or use the Tip411 information on the Sheriff's Office website to report anonymously.
