The Greene County Sheriff's Department says Ronald Lehman, 50, and Rennae Lehman, 43, were riding a motorcycle on State Road 157 near Worthington Monday evening July 21, 2014.
When Ronald applied his breaks to avoid hitting a deer both he and Rennae were thrown from the bike.
Ronald refused treatment for minor injuries.
But Rennae suffered a severe head injury and later died at an Indianapolis hospital.
Police say neither of them were wearing a helmet.
