The Cass County Sheriff’s Department K-9 Nellie is the hero of a 70-year-old Cassopolis man. Michael Cox got lost Sunday night in a wooded area near his home, and his caretaker called police when he went for a walk around 7:45 pm and hadn’t come back by 9. The sheriff’s department says Nellie led handler Deputy Graves to Cox, who was found laying behind some thick bush shortly before midnight. He was cleared by medics with Life Care Ambulance and went home. His caretaker had called police due to concerns over the man’s medical issues. The discovery by Nellie followed several hours of searching by friends and deputies.
