The Monroe County Sheriff’s Office is investigating a Sunday incident in Sparta that left one person dead and two others suffering serious injuries. A 9-1-1 call brought deputies to the home shortly before noon. Two of the victims were taken to a hospital and the third was dead by the time deputies arrived. They had all been injured with what authorities are calling “an edged weapon.” The suspect was outside the home with a rifle and he had shot himself. Deputies say he was taken into custody. No names have been released. The sheriff’s office says the homicide case is under investigation.
