Authorities in Jackson County say one person is dead and a second one is injured after an incident last week. Deputies responded to a Thursday night call about a man needing emergency medical treatment. Lifesaving measures were performed until Black River Falls E-M-S arrived. While deputies were trying to find out how the man got hurt, they found a woman there who also needed emergency medical treatment. No names have been released. The man was airlifted to Marshfield Hospital where he died later Thursday night. The woman was taken to Mayo Clinic Health System in Eau Claire. Her medical condition hasn’t been reported.
